From afec1aba08607b18cfd00fdcd6525aeca0e187bf Mon Sep 17 00:00:00 2001 From: Lad Prabhakar Date: Mon, 29 Jul 2024 21:26:43 +0100 Subject: dt-bindings: clock: renesas: Document RZ/V2H(P) SoC CPG Document the device tree bindings for the Renesas RZ/V2H(P) SoC Clock Pulse Generator (CPG). CPG block handles the below operations: - Generation and control of clock signals for the IP modules - Generation and control of resets - Control over booting - Low power consumption and power supply domains Also define constants for the core clocks of the RZ/V2H(P) SoC. Note the core clocks are a subset of the ones which are listed as part of section 4.4.2 of HW manual Rev.1.01 which cannot be controlled by CLKON register.
