Subject: [PATCH 03/14] dt-bindings: nvmem: rockchip,otp: Add compatible for RK3576

From: Heiko Stuebner <heiko@...ech.de>

Document the OTP memory found on Rockchip RK3576 SoC.

The RK3576 uses the same set of clocks as the px30/rk3308
but has one reset more, so adapt the binding to handle this
variant as well.
