From 3105836c9e5d7c2823dc5817b60d6940bb1b817f Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Tue, 29 Jun 2021 12:04:22 +0200 Subject: [PATCH] clk: stm32mp1: add support of SYSCFG clock Add the support of SYSCFG clock used by syscon driver to prepare the clock management of STM32MP_SYSCON_SYSCFG. This clock is already defined in kernel device tree, stm32mp151.dtsi but not yet supported in the syscon driver: syscfg: syscon@50020000 { compatible = "st,stm32mp157-syscfg", "syscon"; reg = <0x50020000 0x400>; clocks = <&rcc SYSCFG>; }; It is safe to support this clock in U-Boot driver with RCC_MC_APB3ENSETR, Bit 11 SYSCFGEN: SYSCFG peripheral clocks enable.
