[U-Boot] [PATCH v1 0/6] arm: imx: cx9020: Migrate to DM_VIDEO and DM_GPIO

[U-Boot] [PATCH v1 0/6] arm: imx: cx9020: Migrate to DM_VIDEO and DM_GPIO

[linux-kernel-dev at beckhoff.com]

From: Steffen Dirkwinkel <s.dirkwinkel@beckhoff.com>


This series migrates mx53cx9020 to DM_VIDEO and DM_GPIO.
The first patch allows the board to boot again by enabling DM_GPIO.
This was broken due to card detect not working with a combination
of previous commits.
Patches 2-4 add ipu device tree nodes for mx53, enable them in the video
driver and migrate the board to using DM_VIDEO.
The last patches remove functions which were used before DM_MMC and
uneccessary includes.


Steffen Dirkwinkel (6):
  dm: arm: imx: cx9020: enable DM_GPIO
  dm: arm: imx: video: add compatible for imx53-ipu
  arm: imx: add ipu to imx53.dts and set dm-pre-reloc
  dm: arm: imx: cx9020: migrate to dm_video
  dm: arm: imx: cx9020: remove unused mmc functions
  arm: imx: cx9020: remove unnecessary includes

[U-Boot] [PATCH v1 1/6] dm: arm: imx: cx9020: enable DM_GPIO

[linux-kernel-dev at beckhoff.com]

From: Steffen Dirkwinkel <s.dirkwinkel@beckhoff.com>

Switch to DM_GPIO and add gpio_request where necessary.
This is needed for DM_VIDEO and fixes an issue with sd card detection
which was introduced by the combination of these commits:

commit 7a0425dd969c ("mmc: fsl_esdhc: make get_cd work well in dm_mmc_ops")
commit 7e04b4c751a1 ("dm: arm: imx: migrate cx9020 to CONFIG_DM_MMC")
