Pull spi updates from Mark Brown:
"This has been quite a busy release, mainly due to the subsystem wide
work Johan Hovold has done to modernise resource allocation for the
subsystem on probe, the subsystem did some very clever allocation
management pre devm which didn't quite mesh comfortably with managed
allocations and made it far too easy to introduce error handling and
removal bugs.
- Cleanup and simplification of controller struct allocation, moving
everything over to devm and making the devm APIs more robust, from
Johan Hovold
- Support for spi-mem devices that don't assert chip select and
support for a secondary read command for memory mapped flashes,
some commits for this are shared with mtd.

- Move the handling of an OF quirk from ASoC to gpiolib-of.c where
other such quirks live
- Use handle_bad_irq() in gpio-ep93xx
- Some other minor tweaks and refactorings
Devicetree bindings:
- Document the Waveshare GPIO controller for DSI TOUCH panels

The number of times that link has gone down at the port level is tracked
by the firmware and sent to the driver via regular DMA writes to an
instance of struct ionic_port_status in the driver's memory.
This statistic was never reported in favor of a driver-derived stat, but
doing it in the driver was never necessary since firmware had been
reporting it the whole time. Since it would be more accurate and true to
the description of the statistic to get this count at the PHY level,
replace the driver-calculated statistic with one derived from the
firmware one and remove the driver-calculated one entirely.
The stat reported by the ethtool .get_link_ext_stats() handler is
normalized to 0 on driver load and any device resets that require the
driver to rebuild state while also handling overflows.

This stat contains the number of total bits that the PHY has received;
it's useful for BER calculations. Add it to the ethtool stats output.
However, since this is one of the new "extra port stats", it's reported
in a different manner than the existing port stats and only
conditionally added to the ethtool stats output list: both the
DEV_CAP_EXTRA_STATS capability must be supported by the firmware, and
the firmware must set the value of the statistic to something other than
IONIC_STAT_INVALID.
To help support this scheme, the extra port stats region is initialized to
0xff's/IONIC_STAT_INVALID by the driver, to ensure the statistics that
the driver knows about but the firmware does not are still invalid
to the driver.

Add a new structure to report additional statistics from the firmware to
struct ionic_port_info. This new struct currently only contains FEC
related statistics, but any new port-level statistics collected by the
firmware would go into it.
The new structure is located in the same area as the unused
ionic_port_pb_stats structure, so this patch also removes that and its
supporting enumerations since they was never used in this driver.
Finally, to indicate firmware support for the new structure, introduce a
new device capability that the driver can use to see if the attached
device supports reporting these extra stats.

The current check will fail if SR-IOV is not initialized for the
physical function; this is because is_physfn is 0 if sriov_init() isn't
run or fails. Change the check that prevents getting the link down count
to use is_virtfn instead so that VFs don't get this functionality, which
was the original intent.

The MxL862xx has two XPCS/SerDes interfaces (XPCS0 for ports 9-12,
XPCS1 for ports 13-16). Each can operate in various single-lane modes
(SGMII, 1000Base-X, 2500Base-X, 10GBase-R, 10GBase-KR, USXGMII) or as
QSGMII or 10G_QXGMII providing four sub-ports per interface.
Implement phylink PCS operations using the firmware's XPCS API:
- pcs_enable/pcs_disable: refcount the sub-ports sharing an XPCS
and power it down once the last sub-port is released.
- pcs_config: configure negotiation mode and CL37/SGMII advertising.
- pcs_get_state: read link state and the link-partner ability word
from firmware and decode using phylink's standard CL37, SGMII, and
USXGMII decoders.
- pcs_an_restart: restart CL37 or CL73 auto-negotiation.
- pcs_link_up: force speed/duplex for SGMII.
- pcs_inband_caps: report per-mode in-band status capabilities.
Register a PCS instance for each SerDes interface and
QSGMII/10G_QXGMII sub-ports during setup. Advertise the supported
interface modes in phylink_get_caps based on port number.
Firmware older than 1.0.84 lacks the XPCS API and instead configures
the SerDes itself, using defaults stored in flash. mac_select_pcs()
returns NULL in that case while the single-lane interface modes stay
advertised, so a CPU port keeps working in the firmware-configured
mode.
Lacking support for expressing PHY-side role modes in Linux only the
MAC-side of SGMII, QSGMII, USXGMII and 10G_QXGMII are implemented for
now.

OA TC6 MAC-PHY appends FCS to the incoming frame. It must be
removed from the frame before being passed to the stack.
With FCS in the frame, many applications, like ping or any
application that uses IP layer may work as they may
carry the packet size information in the protocol.
Application like ptp4l, particularly if it uses layer 2
for its communication, it will fail with "bad message" due to
the extra 4 bytes added by the presence of FCS.

According OPEN Alliance 10BASET1x MAC-PHY Serial Interface
specification, interrupt is active low, level triggered.
Code used edge triggered interrupt which has the risk of losing an
interrupt on instances like when interrupt is disabled. Level
triggered interrupt won't be deasserted unless handler runs and
clear the interrupting conditions.
Interrupt handler mechanism is changed to threaded irq from
interrupt handler and kernel thread waiting on work queue.
Threaded irq mechanism is best suited for level triggered interrupt
as it disables the interrupt until handler is run in thread level,
while giving us an ability to have interrupt context handler to
signal the threaded irq handler.
Introduced a logic to disable the device interrupt on error. Error
could be due in data chunk's header and footer or SPI interface itself.
This will avoid having repeated interrupts, in case the driver couldn't
recover from the error condition with the available recovery mechanism.

emac_xsk_xmit_zc() has the same issue as the fixed emac_xmit_xdp_frame():
it always sets the CPPI5 descriptor destination tag to emac->port_id,
which directs the PRU firmware to transmit on only one slave port in HSR
mode, breaking redundancy.
Apply the same fix: in HSR offload mode when NETIF_F_HW_HSR_DUP is set,
use PRUETH_UNDIRECTED_PKT_DST_TAG (port 0) so the PRU duplicates frames
to both ports. Also set PRUETH_UNDIRECTED_PKT_TAG_INS when
NETIF_F_HW_HSR_TAG_INS is set so the PRU re-inserts the HSR sequence tag
that was stripped by the PRU on RX before the XDP program saw the frame.
This ensures XSK XDP_TX frames in HSR mode are treated identically to
skb TX via hsr0.

emac_xmit_xdp_frame() always sets the CPPI5 descriptor destination
tag to emac->port_id, which directs the PRU firmware to transmit
the frame on that specific slave port only. In HSR offload mode
this bypasses the firmware's HSR duplication logic: the frame goes
out on one ring leg and never appears on the other, breaking HSR
redundancy for XDP_TX paths.
icssg_ndo_start_xmit() already handles this correctly: when HSR
offload mode is active and NETIF_F_HW_HSR_DUP is set it substitutes
PRUETH_UNDIRECTED_PKT_DST_TAG (port 0) so the PRU duplicates the
frame to both slave ports. It also sets PRUETH_UNDIRECTED_PKT_TAG_INS
in epib[1] when NETIF_F_HW_HSR_TAG_INS is set so the PRU inserts the
HSR sequence tag, which XDP_TX frames lack (the tag is stripped by
the PRU on RX before the frame reaches the XDP program).
Apply the same logic in emac_xmit_xdp_frame() so XDP_TX frames in
HSR mode are treated identically to skb TX via hsr0.

emac_rx_packet_zc() calls prueth_rx_alloc_zc() with count (frames
received in the current NAPI poll) as the allocation budget. Two
problems arise from this:
1. When the CPPI5 descriptor pool is exhausted (avail_desc == 0,
FDQ already holds the maximum number of descriptors), count > 0
still triggers allocation attempts that all fail, spamming the
kernel log with "rx push: failed to allocate descriptor" at
high packet rates.
2. The XSK wakeup condition "ret < count" is wrong when avail_desc
is zero: ret == 0 and count can be up to 64, so the condition is
always true. This causes ~200 spurious ndo_xsk_wakeup() calls
per second even when the FDQ is already full, wasting CPU cycles
in repeated NAPI invocations that process zero frames.
Fix both by introducing alloc_budget = min(budget, avail_desc):
- When avail_desc == 0 no allocation is attempted, avoiding pool
exhaustion errors. The wakeup condition "ret < alloc_budget"
evaluates to 0 < 0 == false, correctly clearing the wakeup flag
so the hardware IRQ re-arms NAPI without spurious kicks.
- In steady state avail_desc == count <= budget, so alloc_budget
== count and behaviour is unchanged.
- After a dry-ring stall (count == 0, avail_desc > 0), alloc_budget
> 0 causes new descriptors to be posted to the FDQ so the hardware
can resume receiving immediately.

In airoha_fe_pse_ports_init(), the inner condition for PPE1 queue
reservation is identical to the for-loop bound, making it always true
and the else branch dead code:
for (q = 0; q < pse_port_num_queues[FE_PSE_PORT_PPE1]; q++) {
if (q < pse_port_num_queues[FE_PSE_PORT_PPE1]) /* always true */
set RSV_PAGES;
else
set 0; /* unreachable */
}
The intended behavior is to reserve pages only for the first half of
the queues, matching the PPE2 implementation on line 334 which
correctly uses the /2 divisor. Fix the PPE1 condition accordingly.

aq_ptp.c / aq_ptp.h:
- Add aq_ptp_state enum (AQ_PTP_FIRST_INIT, AQ_PTP_LINK_UP,
AQ_PTP_NO_LINK) to distinguish first init from link-change events;
on AQC113 only reset the TSG clock on first init to avoid disrupting
ongoing synchronization.
- Add aq_ptp_dpath_enable() for comprehensive L3/L4 PTP filter
setup/teardown, replacing the previous single-filter approach with
an array of 4 slots for IPv4 and IPv6 PTP multicast addresses
(224.0.1.129, 224.0.0.107, ff0e::181, ff02::6b).
- Add aq_ptp_parse_rx_filters() to map hwtstamp_rx_filters to L2/L4
enable flags and call aq_ptp_dpath_enable().
- Re-apply RX filters on link change (hardware state lost after reset).
- Extend PTP ring alloc/init/start/stop to handle AQC113 PTP ring ops.
- Add per-instance PTP offset table for AQC113 with empirically measured
values at 100M/1G/2.5G/5G/10G link speeds.
- Export aq_ptp_dpath_enable() and updated ring helpers in aq_ptp.h.
aq_hw.h:
- Include hw_atl2/hw_atl2.h for AQC113 PTP type definitions.
aq_nic.c:
- Account for PTP IRQ vector (AQ_HW_PTP_IRQS) in vector count math.
- Call hw_atl2 PTP re-enable hook after hardware reset in
aq_nic_update_link_status().
aq_pci_func.c:
- Pass PTP IRQ index to aq_ptp_irq_alloc() in probe path.

aq_ring.h / aq_ring.c:
- Add ptp_ts_deadline field to aq_ring_s to track TX timestamp timeout.
- In aq_ring_tx_clean(): when hw_ring_tx_ptp_get_ts() returns 0 (HW not
yet written back the timestamp), clear buff->is_mapped and buff->pa
before breaking to prevent double dma_unmap on retry. When
ptp_ts_deadline expires, dequeue and drop the head of skb_ring to keep
it in lockstep with buff_ring, then clear request_ts and free the skb
via dev_kfree_skb_any() to unblock the ring.
aq_main.c:
- Add IPv6 PTP packet detection in aq_ndev_start_xmit() using
ipv6_hdr()->nexthdr for ETH_P_IPV6 frames, steering them through
aq_ptp_xmit() alongside the existing IPv4 path.
- Use PTP_EV_PORT/PTP_GEN_PORT constants instead of magic numbers 319/320.
- Remove duplicate aq_reapply_rxnfc_all_rules() and
aq_filters_vlans_update()
calls from aq_ndev_open() - now covered by aq_nic_start(), which also
ensures filters are restored correctly after PM resume.
aq_nic.c:
- Move aq_reapply_rxnfc_all_rules() and aq_filters_vlans_update() into
aq_nic_start() after hardware init, replacing the duplicate calls that
were removed from aq_ndev_open().

- enable_ptp: enable/disable PTP counter with clock selection
- hw_ring_tx_ptp_get_ts: read TX timestamp from descriptor writeback
- hw_tx_ptp_ring_init/hw_rx_ptp_ring_init: per-ring PTP initialization
- hw_get_clk_sel: query active TSG clock selection
Update existing hw_ops signatures to support AQC113 dual-clock
architecture:
- hw_gpio_pulse: add clk_sel and hightime parameters
- hw_extts_gpio_enable: add channel parameter
Add PTP-related hardware defines:
- AQ_HW_TXD_CTL_TS_EN/TS_TSG0 for TX descriptor timestamp control
- AQ2_HW_PTP_COUNTER_HZ for AQC113 TSG clock frequency
- AQ_HW_PTP_IRQS for PTP interrupt vector accounting
- PTP enable flags (L2/L4) and TSG clock selection constants
Add request_ts and clk_sel bitfields to aq_ring_buff_s for per-packet
TX timestamp request tracking.
Update hw_atl_b0.c (AQC107) implementations:
- Adapt gpio_pulse and extts_gpio_enable to new signatures
- Add TX descriptor timestamp bits for AQC113 when ANTIGUA chip
feature is detected

Add PTP traffic class (TC) buffer reservation and TX path
improvements for AQC113:
- Reserve dedicated TX and RX buffer space for PTP TC when PTP is
enabled, reducing user TC buffers accordingly (TX: 8KB, RX: 16KB).
- Configure PTP TC with no flow control and highest priority
scheduling to ensure timely PTP packet transmission.
TX path improvements:
- Increase TX data and descriptor read-request limits when firmware
has already enabled extended PCIe tag mode.
Also simplify RSS queue calculation in hw_atl2_hw_rss_set() by
extracting to a local variable and use unsigned types for loop
variables to match their usage.

Implement complete RX filter management for AQC113 hardware:
- Add tag-based ethertype filter policy (hw_atl2_filter_tag_get/put)
that allocates and releases ART tags for L2 ethertype filters.
- Add L3/L4 filter sharing via serialized usage counters in
hw_atl2_l3_filter/hw_atl2_l4_filter, managed through
hw_atl2_rxf_l3_get/put and hw_atl2_rxf_l4_get/put.
- Implement L3 (IPv4/IPv6 source/destination address and protocol)
filter find, get (program HW and increment refcount), and put
(decrement refcount and clear HW when last user releases).
- Implement L4 (TCP/UDP/SCTP source/destination port) filter management
with the same find/get/put pattern.
- Add combined L3L4 filter configuration (hw_atl2_new_fl3l4_configure)
that translates legacy aq_rx_filter_l3l4 commands into AQC113 separate
L3+L4 filter programming with Action Resolver Table (ART) entries.
- Add L2 ethertype filter set/clear (hw_atl2_hw_fl2_set/clear) with
tag-based ART integration.
- Wire .hw_filter_l2_set, .hw_filter_l2_clear, .hw_filter_l3l4_set
into hw_atl2_ops.

Fix initialization issues in hw_atl2 to correctly support AQC113:
- hw_atl2_hw_reset: replace unconditional priv memset with selective
field clears so that l3l4_filters[].l3_index and l4_index can be
initialized to -1 (not allocated) rather than 0; 0 is a valid filter
index and would incorrectly appear as an occupied slot after a reset.
- hw_atl2_hw_init_new_rx_filters: use firmware-reported ART section
base and count (clamped to 16) instead of hardcoded 0xFFFF mask;
enable simultaneous IPv4/IPv6 L3 filter mode (rpf_l3_v6_v4_select);
tag the UC MAC slot using firmware-supplied l2_filters_base_index
instead of hardcoded HW_ATL2_MAC_UC.
- hw_atl2_hw_init_rx_path: enable only the firmware-assigned MAC slot
(priv->l2_filters_base_index) instead of always slot 0.
- Add hw_atl2_hw_mac_addr_set() that programs the MAC address into
the firmware-assigned L2 filter slot. Wire into hw_atl2_ops
replacing the A1 hw_atl_b0_hw_mac_addr_set; call it from hw_init.
- Wire .hw_get_regs into hw_atl2_ops.
