| LT9611 DSI to HDMI bridge |
| |
| |
| Required properties: |
| - compatible: Must be "lt,lt9611" |
| - reg: Main I2C slave ID (for I2C host driver) |
| - lt,irq-gpio: Main IRQ gpio mapping |
| - lt,reset-gpio Main reset gpio mapping |
| |
| |
| Optional properties: |
| - lt,hdmi-ps-gpio: gpio mapping for HDMI PS |
| - lt,hdmi-en-gpio: gpio mapping for HDMI EN |
| |
| - lt,supply-entries: A node that lists the elements of the supply used to |
| power the bridge. There can be more than one instance |
| of this binding, in which case the entry would be |
| appended with the supply entry index. |
| e.g. lt,supply-entry@0 |
| -- lt,supply-name: name of the supply (vdd/vcc) |
| -- lt,supply-min-voltage: minimum voltage level (uV) |
| -- lt,supply-max-voltage: maximum voltage level (uV) |
| -- lt,supply-enable-load: load drawn (uA) from enabled supply |
| -- lt,supply-disable-load: load drawn (uA) from disabled supply |
| -- lt,supply-ulp-load: load drawn (uA) from supply in ultra-low power mode |
| -- lt,supply-pre-on-sleep: time to sleep (ms) before turning on |
| -- lt,supply-post-on-sleep: time to sleep (ms) after turning on |
| -- lt,supply-pre-off-sleep: time to sleep (ms) before turning off |
| -- lt,supply-post-off-sleep: time to sleep (ms) after turning off |
| |
| - lt,non-pluggable: Boolean to indicate if display is non pluggable. |
| - lt,preferred-mode: Preferred display mode. |
| - lt,customize-modes: Customized modes when it's non-pluggable display. |
| e.g. lt,customize-mode-id@0 |
| -- lt,mode-h-active: Horizontal active pixels for this mode. |
| -- lt,mode-h-front-porch: Horizontal front porch in pixels for this mode. |
| -- lt,mode-h-pulse-width: Horizontal sync width in pixels for this mode. |
| -- lt,mode-h-back-porch: Horizontal back porch in pixels for this mode. |
| -- lt,mode-h-active-high: Boolean to indicate if mode horizontal polarity is active high. |
| -- lt,mode-v-active: Vertical active lines for this mode. |
| -- lt,mode-v-front-porch: Vertical front porch in lines for this mode. |
| -- lt,mode-v-pulse-width: Vertical sync width in lines for this mode. |
| -- lt,mode-v-back-porch: Vertical back porch in lines for this mode. |
| -- lt,mode-v-active-high: Boolean to indicate if mode vertical polarity is active high. |
| -- lt,mode-refersh-rate: Mode refresh rate in hertz. |
| -- lt,mode-clock-in-khz: Mode pclk in KHz. |
| |
| Required nodes: |
| |
| The LT9611 has one video port. Its connection is modelled using the OF |
| graph bindings specified in Documentation/devicetree/bindings/graph.txt. |
| Video port 0 is for the DSI input. The remote endpoint phandle should |
| be a reference to a valid mipi_dsi_host device node. |
