Input: tegra-kbc - revise device tree support
This is an incremental patch updating to the revised bindings for matrix keyboards. This includes an optional "linux,fn-keymap" binding that is not yet implemented, that will be used to specify the Fn-key modifier layout if needed.

Required properties:
- compatible: "nvidia,tegra20-kbc"
-Optional properties:
-- debounce-delay: delay in milliseconds per row scan for debouncing
-- repeat-delay: delay in milliseconds before repeat starts
-- ghost-filter: enable ghost filtering for this device
-- wakeup-source: configure keyboard as a wakeup source for suspend/resume
+Optional properties, in addition to those specified by the shared
+matrix-keyboard bindings:
+
+- linux,fn-keymap: a second keymap, same specification as the
+ matrix-keyboard-controller spec but to be used when the KEY_FN modifier
+ key is pressed.
+- nvidia,debounce-delay-ms: delay in milliseconds per row scan for debouncing
+- nvidia,repeat-delay-ms: delay in milliseconds before repeat starts
+- nvidia,ghost-filter: enable ghost filtering for this device
+- nvidia,wakeup-source: configure keyboard as a wakeup source for suspend/resume
Example:
keyboard: keyboard {
compatible = "nvidia,tegra20-kbc";
reg = <0x7000e200 0x100>;
- ghost-filter;
+ nvidia,ghost-filter;
};
