2023-02-27T18:04:49+00:00

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"

irqchip/irq-imx-gpcv2: Mark fwnode device as not initialized

2023-02-08T12:37:55+00:00

Since this device is only partially initialized by the irqchip driver,
we need to mark the fwnode device as not initialized. This is to let
fw_devlink know that the device will be completely initialized at a
later point. That way, fw_devlink will continue to defer the probe of
the power domain consumers till the power domain driver successfully
binds to the struct device and completes the initialization of the
device.

soc: imx: imx8mp-blk-ctrl: set HDMI LCDIF panic read hurry level

2023-01-30T00:48:19+00:00

Same as done for both LCDIF interfaces in the MEDIA domain, set
the panic priority of the LCDIF instance in the HDMI domain to
the maximium NoC priority of 7 to minimize chances of display
underflows.

soc: imx: imx93-src: No need to set device_driver owner

2023-01-01T05:29:14+00:00

There is no need to exclusively set the .owner member of the struct
device_driver when defining the platform_driver struct. The Linux core
takes care of setting the .owner member as part of the call to
module_platform_driver() helper function.

Issue identified using the platform_no_drv_owner.cocci Coccinelle
semantic patch.

soc: imx: imx8m-blk-ctrl: set LCDIF panic read hurry level

2023-01-01T05:25:38+00:00

When the LCDIF block signals a panic condition due to the display FIFO
falling below the threshold, the priority at the NoC level is boosted
to the value set in the LCDIF_ARCACHE_CTRL register of i.MX8MP mediamix
blk-ctrl. Same as all other blk-ctrl registers this register is reset
when the domain is powered down. Initialize the panic hurry levels for
both LCIF interfaces to the maximium priority (same as downstream TF-A
and proven to work with the other priorities set in the interconnect
driver) when coming back from power down.

Setting the device name after it has been registered confuses the sysfs
cleanup paths. This has already been fixed for the imx8m-blk-ctrl driver in
b64b46fbaa1d ("Revert "soc: imx: imx8m-blk-ctrl: set power device name""),
but the same problem exists in imx8mp-blk-ctrl.
