* STMicroelectronics STM32 lcd-tft display controller
|
||
|
|
|
||
|
|
- ltdc: lcd-tft display controller host
|
||
|
|
must be a sub-node of st-display-subsystem
|
||
|
|
Required properties:
|
||
|
|
- compatible: "st,stm32-ltdc"
|
||
|
|
- reg: Physical base address of the IP registers and length of memory mapped region.
|
||
|
|
- clocks: A list of phandle + clock-specifier pairs, one for each
|
||
|
|
entry in 'clock-names'.
|
||
|
|
- clock-names: A list of clock names. For ltdc it should contain:
|
||
|
|
- "lcd" for the clock feeding the output pixel clock & IP clock.
|
||
|
|
- resets: reset to be used by the device (defined by use of RCC macro).
|
||
|
|
Required nodes:
|
||
|
|
- Video port for RGB output.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
/ {
|
||
|
|
...
|
||
|
|
soc {
|
||
|
|
...
|
||
|
|
ltdc: display-controller@40016800 {
|
||
|
|
compatible = "st,stm32-ltdc";
|
||
|
|
reg = <0x40016800 0x200>;
|
||
|
|
interrupts = <88>, <89>;
|
||
|
|
resets = <&rcc STM32F4_APB2_RESET(LTDC)>;
|
||
|
|
clocks = <&rcc 1 CLK_LCD>;
|
||
|
|
clock-names = "lcd";
|
