Pull clk updates from Stephen Boyd:
 "It looks like a smaller batch of clk updates this time around.

  In the core framework we just have some minor tweaks and a debugfs
  feature, so not much to see there. The driver updates are fairly well
  split between AT91 and Qualcomm clk support. Adding those two drivers
  together equals about 50% of the diffstat.

  Otherwise, the big amount of work this time was on supporting
  Broadcom's Raspberry Pi firmware clks.

  Highlights:

  Core:
   - Document clk_hw_round_rate() so it gets some more use
   - Remove unused __clk_get_flags()
   - Add a prepare/enable debugfs feature similar to rate setting

  New Drivers:
   - Add support for SAMA7G5 SoC clks
   - Enable CPU clks on Qualcomm IPQ6018 SoCs
   - Enable CPU clks on Qualcomm MSM8996 SoCs
   - GPU clk support for Qualcomm SM8150 and SM8250 SoCs
   - Audio clks on Qualcomm SC7180 SoCs
   - Microchip Sparx5 DPLL clk
   - Add support for the new Renesas RZ/G2H (R8A774E1) SoC

  Updates:
   - Make defines for bcm63xx-gate clks to use in DT
   - Support BCM2711 SoC firmware clks
   - Add HDMI clks for BCM2711 SoCs
   - Add RTC related clks on Ingenic SoCs
   - Support USB PHY clks on Ingenic SoCs
   - Support gate clks on BCM6318 SoCs
   - RMU and DMAC/GPIO clock support for Actions Semi S500 SoCs
   - Use poll_timeout functions in Rockchip clk driver
   - Support Rockchip rk3288w SoC variant
   - Mark mac_lbtest critical on Rockchip rk3188
   - Add CAAM clock support for i.MX vf610 driver
   - Add MU root clock support for i.MX imx8mp driver
   - Amlogic g12: add neural network accelerator clock sources
   - Amlogic meson8: remove critical flag for main PLL divider
   - Amlogic meson8: add video decoder clock gates
   - Convert one more Renesas DT binding to json-schema
   - Enhance critical clock handling on Renesas platforms to only
     consider clocks that were enabled at boot time"

2020-07-28T06:09:25+00:00

The Protection Domains (PD) have a mechanism to keep its resources
enabled until the PD down indication is acked. Reorder the PD state
indication ack so that clients get to release the relevant resources
before the PD goes down.

soc: qcom: geni: Fix NULL pointer dereference

2020-07-20T20:11:15+00:00

pdev struct doesn't exits for the devices whose status are disabled
from DT node, in such cases NULL is returned from 'of_find_device_by_node'
Later when we try to get drvdata from pdev struct NULL pointer dereference
is triggered.

Add a NULL check for return values to fix the issue.

We were hitting this issue when one of QUP is disabled.

tty: serial: qcom-geni-serial: Drop the icc bw votes in suspend for console

2020-07-14T05:43:43+00:00

When using the geni-serial as console, its important to be
able to hit the lowest possible power state in suspend,
even with no_console_suspend.
The only thing that prevents it today on platforms like the sc7180
is the interconnect BW votes, which we certainly don't need when
the system is in suspend. So in the suspend handler mark them as
ACTIVE_ONLY (0x3) and on resume switch them back to the ALWAYS tag (0x7)

making it public to allow other drivers use it.
The accesses must be separated with a single spinlock,

iov_iter: Move unnecessary inclusion of crypto/hash.h

2020-06-30T13:34:23+00:00

The header file linux/uio.h includes crypto/hash.h which pulls in
most of the Crypto API.  Since linux/uio.h is used throughout the
kernel this means that every tiny bit of change to the Crypto API
causes the entire kernel to get rebuilt.

This patch fixes this by moving it into lib/iov_iter.c instead
where it is actually used.

This patch also fixes the ifdef to use CRYPTO_HASH instead of just
CRYPTO which does not guarantee the existence of ahash.

Unfortunately a number of drivers were relying on linux/uio.h to
provide access to linux/slab.h.  This patch adds inclusions of
linux/slab.h as detected by build failures.

Also skbuff.h was relying on this to provide a declaration for
ahash_request.  This patch adds a forward declaration instead.
