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.

From: dillon min <dillon.minfei@gmail.com> V5's update based on Mark Brown's suggestion, use 'SPI_MASTER_MUST_RX' for SPI_SIMPLEX_RX mode on stm32 spi controller. V5: 1 instead of add send dummy data out under SIMPLEX_RX mode, add flags 'SPI_CONTROLLER_MUST_TX' for stm32 spi driver 2 bypass 'SPI_CONTROLLER_MUST_TX' and 'SPI_CONTROLLER_MUST_RX' under 'SPI_3WIRE' mode V4: According to alexandre torgue's suggestion, combine ili9341 and l3gd20's modification on stm32f429-disco board to one patchset. Changes: ili9341: 1 update ili9341 panel driver according to Linus's suggestion 2 drop V1's No.5 patch, sumbit new changes for clk-stm32f4 3 merge l3gd20's change to this patchset V3: 1 merge original tiny/ili9341.c driver to panel/panel-ilitek-ili9341.c to support serial spi & parallel rgb interface in one driver. 2 update ilitek,ili9341.yaml dts binding documentation. 3 update stm32f429-disco dts binding V2: 1 verify ilitek,ili9341.yaml with make O=../linux-stm32 dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/panel/ ilitek,ili9341.yaml V1: 1 add ili9341 drm panel driver 2 add ltdc, spi5 controller for stm32f429-disco 3 add ltdc, spi5 pin map for stm32f429-disco 4 add docs about ili9341 5 fix ltdc driver loading hang in clk set rate bug L3gd20: V3: 1 merge stm32f429-disco dtbs binding with ili9341 part V2: 1 insert blank line at stm32f420-disco.dts line 143 2 add more description for l3gd20 in commit message V1: 1 enable spi5 controller on stm32f429-disco (dts) 2 add spi5 pinmap for stm32f429-disco (dts) 3 add SPI_SIMPLEX_RX, SPI_3WIRE_RX support for stm32f4 dillon min (8): 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 dt-bindings: display: panel: Add ilitek ili9341 panel bindings 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: Add ilitek ili9341 panel driver 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 be coexit with 'SPI_3WIRE' mode .../bindings/display/panel/ilitek,ili9341.yaml | 69 ++ arch/arm/boot/dts/stm32f4-pinctrl.dtsi | 67 + arch/arm/boot/dts/stm32f429-disco.dts | 48 + arch/arm/boot/dts/stm32f429.dtsi | 3 + drivers/clk/clk-stm32f4.c | 7 +- drivers/gpu/drm/panel/Kconfig | 12 + drivers/gpu/drm/panel/Makefile | 1 + drivers/gpu/drm/panel/panel-ilitek-ili9341.c | 1301 ++++++++++++++++++++ drivers/spi/spi-stm32.c | 19 +- drivers/spi/spi.c | 3 +- 10 files changed, 1521 insertions(+), 9 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/panel/ilitek,ili9341.yaml create mode 100644 drivers/gpu/drm/panel/panel-ilitek-ili9341.c
