Currently targeted at +defining the keys in the scope of linux key codes since that is a stable and +standardized interface at this time. + +Required properties: +- linux,keymap: an array of packed 1-cell entries containing the equivalent + of row, column and linux key-code. The 32-bit big endian cell is packed + as: + row << 24 | column << 16 | key-code + +Optional properties: +Some users of this binding might choose to specify secondary keymaps for +cases where there is a modifier key such as a Fn key. Proposed names +for said properties are "linux,fn-keymap" or with another descriptive +word for the modifier other from "Fn". + +Example: + linux,keymap = < 0x00030012 + 0x0102003a >; |
