soc: imx: gpcv2: Assert reset before ungating clock

2022-09-15T08:47:12+00:00

[ Upstream commit df88005bd81b80c944d185554e264a4b0f993c37 ]

In case the power domain clock are ungated before the reset is asserted,
the system might freeze completely. This is likely due to a device is an
undefined state being attached to bus, which sporadically leads to a bus
hang. Assert the reset before the clock are enabled to assure the device
is in defined state before being attached to bus.

Revert "soc: imx: imx8m-blk-ctrl: set power device name"

[ Upstream commit b64b46fbaa1da626324f304bcb5fe0662f28b6ce ]

This reverts commit 8239d67f59cf522dd4f7135392a2f9a3a25f9cff.

This change confuses the sysfs cleanup path since the rename is done
after the device registration.

Merge tag 'arm-drivers-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2022-05-26T17:32:47+00:00

Pull ARM driver updates from Arnd Bergmann:
 "There are minor updates to SoC specific drivers for chips by Rockchip,
  Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom.

  Noteworthy driver changes include:

   - Several conversions of DT bindings to yaml format.

   - Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.

   - Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
     and support for more chips in the RPMh power domains and the
     soc-id.

   - NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.

   - Apple M1 gains support for the on-chip NVMe controller, making it
     possible to finally use the internal disks. This also includes SoC
     drivers for their RTKit IPC and for the SART DMA address filter.

  For other subsystems that merge their drivers through the SoC tree, we
  have

   - Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
     SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
     now has a cache for firmware argument structures as an
     optimization, and SCMI now supports the 3.1 version of the
     specification.

   - Reset controller updates to Amlogic, ASpeed, Renesas and ACPI
     drivers

   - Memory controller updates for Tegra, and a few updates for other
     platforms"
