Pull ARM SoC driver updates from Arnd Bergmann:
 "As usual, there are lots of minor driver changes across SoC platforms
  from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
  These usually add support for additional chip variations in existing
  drivers, but also add features or bugfixes.

  The SCMI firmware subsystem gains a unified raw userspace interface
  through debugfs, which can be used for validation purposes.

  Newly added drivers include:

   - New power management drivers for StarFive JH7110, Allwinner D1 and
     Renesas RZ/V2M

   - A driver for Qualcomm battery and power supply status

   - A SoC device driver for identifying Nuvoton WPCM450 chips

   - A regulator coupler driver for Mediatek MT81xxv"

More Qualcomm driver updates for 6.3

The qcom_scm.h file is moved into firmware/qcom, to avoid having any
Qualcomm-specific files directly in include/linux.

Support for PMIC GLINK is introduced, which on newer Qualcomm platforms
provides an interface to the firmware implementing battery management
and USB Type-C handling. Together with the base driver comes the custom
altmode support driver.

SMD RPM gains support for IPQ9574, and socinfo is extended with support
for revision 17 of the information format and soc_id for IPQ5332 and
IPQ8064 are added.

The qcom_stats  is changes not to fail when not all parts are
initialized.

firmware: xilinx: Clear IOCTL_SET_SD_TAPDELAY using PM_MMIO_WRITE

2023-01-05T09:18:07+00:00

In case the tap delay required by Arasan SDHCI is set to 0, the current
embeddedsw firmware unconditionally writes IOU_SLCR SD_ITAPDLY to 0x100
(SD0_ITAPDLYENA=1, SD0_ITAPDLYSEL=0). Previous behavior was to keep the
IOU_SLCR SD_ITAPDLY set to 0x0. There is some sort of difference in the
behavior between SD0_ITAPDLYENA=1/0 with the same SD0_ITAPDLYSEL=0, even
though the behavior should be identical -- zero delay added to rxclk_in
line. The former breaks HS200 training in low temperature conditions.

Write IOU_SLCR SD_ITAPDLY register to 0 using PM_MMIO_WRITE which seem
to allow unrestricted WRITE access (and PM_MMIO_READ which allows read
access) to the entire address space. This way, it is possible to work
around the defect in IOCTL_SET_SD_TAPDELAY design which does not permit
clearing SDx_ITAPDLYENA bit.

Note that the embeddedsw firmware does not permit clearing the SD_ITAPDLY
SD0_ITAPDLYENA bit, this bit can only ever be set by the firmware and it
is often impossible to update the possibly broken firmware.

Merge tag 'rproc-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

2022-12-21T17:37:14+00:00

Pull remoteproc updates from Bjorn Andersson:
 "rproc-virtio device names are now auto generated, to avoid conflicts
  between remoteproc instances.

  The imx_rproc driver is extended with support for communicating with
  and attaching to a running M4 on i.MX8QXP, as well as support for
  attaching to the M4 after self-recovering from a crash. Support is
  added for i.MX8QM and mailbox channels are reconnected during the
  recovery process, in order to avoid data corruption.

  The Xilinx Zynqmp firmware interface is extended and support for the
  Xilinx R5 RPU is introduced.

  Various resources leaks, primarily in error paths, throughout the
  Qualcomm drivers are corrected.

  Lastly a fix to ensure that pm_relax is invoked even if the remoteproc
  instance is stopped between a crash is being reported and the recovery
  handler is scheduled"

firmware: xilinx: Add RPU configuration APIs

2022-11-25T16:11:47+00:00

This patch adds APIs to access to configure RPU and its
processor-specific memory.

That is query the run-time mode of RPU as either split or lockstep as well
as API to set this mode. In addition add APIs to access configuration of
the RPUs' tightly coupled memory (TCM).

Add shutdown/wakeup a resource eemi operations to shutdown

Note alignment of args matches convention of other fn's in this file.
The reason being that the long fn name results in aligned args that
otherwise go over 80 chars so shift right to avoid this
