scsi: ufs: rockchip,rk3576-ufshc: dt-bindings: Add new mphy reset item

2026-05-23T11:06:56+00:00

[ Upstream commit bdce3a69c578090dd5e3c77bcdaaca10c3a41e34 ]

Add the mphy reset property to the devicetree bindings for the Rockchip
RK3576 UFS host controller. The mphy reset signal is used to reset the
physical adapter. Resetting other components while leaving the mphy unreset
may occasionally prevent the UFS controller from successfully linking up
with the device.

This addresses an intermittent hardware bug where the UFS link fails to
establish under specific timing conditions with certain chips. While
difficult to reproduce initially, this issue was consistently observed in
downstream testing and requires explicit mphy reset control for full
stability.

Although this change increases the maxItems for resets and adds a new entry
(which technically alters the binding ABI), it does not break compatibility
for existing Linux systems. The driver uses
devm_reset_control_array_get_exclusive() to manage resets, allowing it to
function correctly with both older Device Trees (without the mphy entry)
and newer ones.

dt-bindings: net: dsa: nxp,sja1105: make spi-cpol optional for sja1110

2026-05-23T11:06:32+00:00

[ Upstream commit 600f01dc4bd0c736b3ffea9f7976136d8bf1b136 ]

Currently, the binding requires 'spi-cpha' for SJA1105 and 'spi-cpol'
for SJA1110.

However, the SJA1110 supports both SPI modes 0 and 2. Mode 2
(cpha=0, cpol=1) is used by the NXP LX2160 Bluebox 3.

On the SolidRun i.MX8DXL HummingBoard Telematics, mode 0 is stable,
while forcing mode 2 introduces CRC errors especially during bursts.

Drop the requirement on spi-cpol for SJA1110.

media: dt-bindings: rockchip,vdec: Mark reg-names required for RK35{76,88}

2026-05-17T15:15:27+00:00

commit a11db8d8b403eba1f82728f440727128e9997edd upstream.

The Rockchip Video Decoder driver expects reg-names to be mandatory for
RK3576 and RK3588 SoCs, however the binding does not currently require
the use of them.

As a consequence, driver would fail to probe with a hypothetical
devicetree that doesn't provide the reg-names for these SoCs, but which
is otherwise a perfectly valid DT from the binding perspective.

Update the binding and make reg-names required for the aforementioned
SoCs.  While this change introduces an ABI break, the expected impact on
potential users would be minimal, if any, since the old SoCs are
unaffected, while the video decoder support for these newer variants in
mainline driver and devicetrees hasn't been released yet.

Moreover, this is also a prerequisite for a subsequent binding update
introducing an alternative reg-names order, according to the
address-based listing in the vendor's datasheet.

media: dt-bindings: rockchip,vdec: Add alternative reg-names order for RK35{76,88}

2026-05-17T15:15:26+00:00

commit 35c8178ed2bd9821a75a406d762b2f2e161f9c70 upstream.

With the introduction of the RK3588 SoC, and RK3576 afterwards, three
register blocks have been provided for the video decoder unit instead of
just one, which are further referenced in vendor's datasheet by 'link
table', 'function' and 'cache'.  The former is present at the top of the
listing, starting at video decoder unit base address.

However, while documenting RK3588, the binding broke the convention
expecting the unit address to indicate the start of the primary register
range, i.e. the 'function' block got listed before the 'link' one.

Since the binding changes have been already released and a fix would
bring up an ABI break, mark the current 'reg-names' ordering as
deprecated and introduce an alternative 'link,function,cache' listing
which follows the address-based ordering according to the TRM.

Additionally, drop the 'reg' description items as the order is not fixed
anymore, while the information they offer is not very relevant anyway.

It's worth noting there are currently no (known) users impacted by these
binding changes, since the video decoder support for the aforementioned
SoCs in mainline driver and devicetrees hasn't been released yet - it
landed in v7.0-rc1 while all DTS updates resulting from this will be
handled before v7.0 is out.

dt-bindings: display: ti, am65x-dss: Fix AM62L DSS reg and clock constraints

2026-05-07T04:11:35+00:00

commit 9c469240997584449cfac51a75d1d3d71968c76f upstream.

The AM62L DSS [1] support incorrectly used the same register and
clock constraints as AM65x, but AM62L has a single video port

Fix this by adding conditional constraints that properly define the
register regions and clocks for AM62L DSS (single video port) versus
other AM65x variants (dual video port).

dt-bindings: net: Fix Tegra234 MGBE PTP clock

2026-04-22T11:22:20+00:00

[ Upstream commit fb22b1fc5bca3c0aad95388933497ceb30f1fb26 ]

The PTP clock for the Tegra234 MGBE device is incorrectly named
'ptp-ref' and should be 'ptp_ref'. This is causing the following
warning to be observed on Tegra234 platforms that use this device:

 ERR KERN tegra-mgbe 6800000.ethernet eth0: Invalid PTP clock rate
 WARNING KERN tegra-mgbe 6800000.ethernet eth0: PTP init failed

Although this constitutes an ABI breakage in the binding for this
device, PTP support has clearly never worked and so fix this now
so we can correct the device-tree for this device. Note that the
MGBE driver still supports the legacy 'ptp-ref' clock name and so
older/existing device-trees will still work, but given that this
is not the correct name, there is no point to advertise this in the
binding.
