-* Tegra keyboard controller
-The key controller has maximum 24 pins to make matrix keypad. Any pin
-can be configured as row or column. The maximum column pin can be 8
-and maximum row pins can be 16 for Tegra20/Tegra30.
-
-Required properties:
-- compatible: "nvidia,tegra20-kbc"
-- reg: Register base address of KBC.
-- interrupts: Interrupt number for the KBC.
-- nvidia,kbc-row-pins: The KBC pins which are configured as row. This is an
- array of pin numbers which is used as rows.
-- nvidia,kbc-col-pins: The KBC pins which are configured as column. This is an
- array of pin numbers which is used as column.
-- linux,keymap: The keymap for keys as described in the binding document
- devicetree/bindings/input/matrix-keymap.txt.
-- clocks: Must contain one entry, for the module clock.
- See ../clocks/clock-bindings.txt for details.
-- resets: Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names: Must include the following entries:
- - kbc
-
-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
-- wakeup-source: configure keyboard as a wakeup source for suspend/resume
- (Legacy property supported: "nvidia,wakeup-source")
-
-Example:
-
-keyboard: keyboard {
- compatible = "nvidia,tegra20-kbc";
- reg = <0x7000e200 0x100>;
- interrupts = <0 85 0x04>;
