Merge tag 'davinci-for-v5.4/fbdev' of git://git.kernel.org/pub/scm/linux/kernel/git...

This converts the da8xx fbdev driver to use GPIO backlight device
and regulator devices. This will finally help get rid of legacy
GPIO API calls and simplify DaVinci GPIO driver.

* tag 'davinci-for-v5.4/fbdev' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci:
  fbdev: da8xx: use resource management for dma
  fbdev: da8xx-fb: drop a redundant if
  fbdev: da8xx-fb: use devm_platform_ioremap_resource()
  fbdev: da8xx: remove panel_power_ctrl() callback from platform data
  ARM: davinci: da850-evm: switch to using a fixed regulator for lcdc
  fbdev: da8xx: add support for a regulator
  ARM: davinci: da850-evm: model the backlight GPIO as an actual device
