The patch adds display support on the stm32f769-disco board. Signed-off-by: Dario Binacchi <dario.binacchi@amarulasolutions.com> --- Changes in v10: - Drop backlight. From a closer analysis of the schematics en.MB1225-F769I-B01_Schematic.pdf and en.mb1166-default-a09-schematic.pdf, it is noticed that the GPIO I14 is connected to an unmounted resistor (n/a), making the backlight functionality via GPIO unusable. Changes in v9: - Rename panel-dsi@0 to panel@0 to fix yaml warnings Changes in v8: - Remove unit name from 'ltdc/port/endpoint@0' to fix the compiling warning: ../arch/arm/boot/dts/st/stm32f769-disco.dts:189.28-191.5: Warning (unit_address_vs_reg): /soc/display-controller@40016800/port/endpoint@0: node has a unit name, but no reg or ranges property arch/arm/boot/dts/st/stm32f769-disco.dts | 64 +++++++++++++++++++++++- 1 file changed, 63 insertions(+), 1 deletion(-)
