Optional properties for main touchpad device:
-- linux,gpio-keymap: An array of up to 4 entries indicating the Linux
- keycode generated by each GPIO. Linux keycodes are defined in
- <dt-bindings/input/input.h>.
-
- linux,gpio-keymap: When enabled, the SPT_GPIOPWN_T19 object sends messages
on GPIO bit changes. An array of up to 8 entries can be provided
indicating the Linux keycode mapped to each bit of the status byte,
#address-cells = <1>;
#size-cells = <0>;
dmas = <&pdma1 0>, <&pdma1 1>;
- dma-names = "rx", "tx";
+ dma-names = "tx", "rx";
clock-names = "i2s_hclk", "i2s_clk";
clocks = <&cru HCLK_I2S0>, <&cru SCLK_I2S0>;
};
- clocks: Must contain an entry for each entry in clock-names.
- clock-names: Shall be "spiclk" for the transfer-clock, and "apb_pclk" for
the peripheral clock.
+- #address-cells: should be 1.
+- #size-cells: should be 0.
+
+Optional Properties:
+
- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
Documentation/devicetree/bindings/dma/dma.txt
- dma-names: DMA request names should include "tx" and "rx" if present.
-- #address-cells: should be 1.
-- #size-cells: should be 0.
