[PATCH v4 0/3] Add ilitek ili9341 panel driver
by dillon.minfei＠gmail.com
From: Dillon Min <dillon.minfei(a)gmail.com>
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].

https://lore.kernel.org/lkml/1590378348-8115-6-git-send-email-dillon.minf...
v4:
- fix m68k-allmodconfig build error which reported by lkp, thanks.
- add Copyright 2018 David Lechner <david(a)lechnology.com>.
v3 link:
https://lore.kernel.org/lkml/1627013203-23099-1-git-send-email-dillon.min...
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 link:
https://lore.kernel.org/lkml/1626853288-31223-1-git-send-email-dillon.min...
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.
