Since the st,sf-tc240t-9370-t dts binding already exist in stm32f429-disco.dts but, the panel driver didn't get accepted from mainline. it's time to submit patch fot it.
This driver can support two different interface by different dts bindings:
- spi+dpi, use spi to configure register, dpi for graphic data. st,sf-tc240t-9370-t
- only spi, just like tiny/ili9341.c (actually, this part is copy from tiny) adafruit,yx240qv29
I was submited the first patch last year, you can find it at [1]. this patch has one major difference from that one, which is replace the low level communication way, from spi_sync() to mipi_dbi_{command, command_stackbuf}() interface, referred from Linus's patch [2].
both the two dpi/dbi interface was tested on stm32f429-disco board, if anyone want to verify this patch, you need apply the clk patch for this board first, you can get it from [3].

v4:
- fix m68k-allmodconfig build error which reported by lkp, thanks.
- add Copyright 2018 David Lechner david@lechnology.com.
v3 link: https://lore.kernel.org/lkml/1627013203-23099-1-git-send-email-dillon.minfei...
v3:
- add Fixes tags.
- collect reviewed-by tags from linus and jagan.
- replace DRM_ERROR() with dev_err() or drm_err().
- remove kernel-doc markers from struct ili9341_config{}.
- reorder include headers.
- remove the struct device *dev from struct ili9341{}.
- restructure the ili9341_probe() function, add two ili9341_{dbi,dpi)_probe() to make it more readable according to jagan's suggestion, thanks.
for the full drm driver exist in drm/panel need Sam and Laurent's feedback. so, not cover this part at this time, will be update later.

v2:
- replace vcc regulator to bulk regulators in driver, from linus suggestion.
- fix dtbs_check warnings on ili9341 dts binding check.
- add bulk regulation node in ilitek,ili9341.yaml.
