Subject: [PATCH v5 0/8] Enable ili9341 and l3gd20 on stm32f429-disco

From: dillon min <dillon.minfei@...il.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
