firmware: imx: Add i.MX95 MISC driver

2024-08-28T20:54:21+00:00

The i.MX95 System manager exports SCMI MISC protocol for linux to do
various settings, such as set board gpio expander as wakeup source.

The driver is to add the support.

firmware: imx-dsp: Convert to platform remove callback returning void

2024-01-04T16:01:14+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

firmware/imx-dsp: Fix use_after_free in imx_dsp_setup_channels()

2023-10-10T02:30:29+00:00

dsp_chan->name and chan_name points to same block of memory,
because dev_err still needs to be used it,so we need free
it's memory after use to avoid use_after_free.

The Kconfig options belongs closer to the corresponding implementations,
hence let's move them from the soc- and firmware subsystem to the pmdomain
subsystem.

Pull ARM SoC driver updates from Arnd Bergmann:
 "The main change this time was the introduction of the drivers/genpd
  subsystem that gets split out from drivers/soc to keep common
  functionality together.

  The SCMI driver subsystem gets an update to version 3.2 of the
  specification. There are also updates to memory, reset and other
  firmware drivers.

  On the soc driver side, the updates are mostly cleanups across a
  number of Arm platforms. On driver for loongarch adds power management
  for DT based systems, another driver is for HiSilicon's Arm server
  chips with their HCCS system health interface.

  The remaining updates for the most part add support for additional
  hardware in existing drivers or contain minor cleanups. Most of these
  are for the Qualcomm Snapdragon platform"

firmware: Explicitly include correct DT includes

2023-08-12T08:31:01+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.
