^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4) Required properties :
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) - compatible : shall contain only one of the following:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) "rockchip,hwspinlock"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) - reg : the register address of hwspinlock
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) - #hwlock-cells : hwlock users only use the hwlock id to represent a specific
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) hwlock, so the number of cells should be <1> here.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) Please look at the generic hwlock binding for usage information for consumers,
