This patchset status is :
dts:
ARM: dts: stm32: Add dma config for spi5
ARM: dts: stm32: Add pin map for ltdc & spi5 on stm32f429-disco board
ARM: dts: stm32: enable ltdc binding with ili9341, gyro l3gd20 on
stm32429-disco board
panel-bindings: Reviewed-by: Rob Herring， need more reviewing to merge
dt-bindings: display: panel: Add ilitek ili9341 panel bindings
clk: Acked-by: Stephen Boyd , need more reviewing to merge
clk: stm32: Fix stm32f429's ltdc driver hang in set clock rate,
fix duplicated ltdc clock register to 'clk_core' case ltdc's clock
turn off by clk_disable_unused()
drm-panel: Reviewed-by: Linus Walleij . need more reviewing to merge
drm/panel: Add ilitek ili9341 panel driver
spi-driver: Acked-by: Mark Brown ，merged into mainline
spi: stm32: Add 'SPI_SIMPLEX_RX', 'SPI_3WIRE_RX' support for stm32f4
spi: flags 'SPI_CONTROLLER_MUST_RX' and 'SPI_CONTROLLER_MUST_TX' can't
becoexit with 'SPI_3WIRE' mode
For ili9341 drivers, it seems to need more time to review, or might be dropped.
since the drm maintainer might create a new interface to support
DPI,DBI,DSI in one driver.
Currently it's under discussion. I will rework the ili9341 driver after that.
But, we can use the existing "drivers/gpu/drm/tiny/ili9341.c" driver to support
ili9341 on stm32f429-disco board only using the spi bus. except the
display refresh performance is not as good as the ltdc interface.
I can submit a new patch just with dts changed this week for it, if you need.
Thanks,
Dillon.
