From 5e15dcb4cbc7906690a759554be082b025d2aa52 Mon Sep 17 00:00:00 2001 From: Alexander Kochetkov Date: Mon, 22 Jun 2020 16:17:09 +0300 Subject: [PATCH] rockchip: clk: rk3188: change APLL to safe 600MHz The commit 84a6a27ae3ff ("rockchip: rk3188: init CPU freq in clock driver") changed ARM clock from 600MHz to 1600MHz. It made boot unstable due to the fact that PMIC at the start generates insufficient voltage for operation. See also: commit f4f57c58b589 ("rockchip: rk3188: Setup the armclk in spl"). Fixes commit 84a6a27ae3ff ("rockchip: rk3188: init CPU freq in clock driver").
