From fcba0f6ab1e2c71bf051557384db48839737407b Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sat, 26 Dec 2020 13:15:54 +0100 Subject: clk: meson: clk-pll: fix initializing the old rate (fallback) for a PLL [ Upstream commit 2f290b7c67adf6459a17a4c978102af35cd62e4a ] The "rate" parameter in meson_clk_pll_set_rate() contains the new rate. Retrieve the old rate with clk_hw_get_rate() so we don't inifinitely try to switch from the new rate to the same rate again.
