^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) This binding is based on the matrix-keymap binding with the following

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) Required Properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) - compatible: Should be "nxp,lpc3220-key"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) - reg: Physical base address of the controller and length of memory mapped
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9)   region.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) - interrupts: The interrupt number to the cpu.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) - clocks: phandle to clock controller plus clock-specifier pair
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) - nxp,debounce-delay-ms: Debounce delay in ms
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) - nxp,scan-delay-ms: Repeated scan period in ms
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) - linux,keymap: the key-code to be reported when the key is pressed

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) Note: keypad,num-rows and keypad,num-columns are required, and must be equal
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) since LPC32xx only supports square matrices
