From 6fffe52fb336ec2063270a7305652a93ea677ca1 Mon Sep 17 00:00:00 2001 From: Peter Geis Date: Wed, 28 Jul 2021 14:00:28 -0400 Subject: [PATCH] clk: rockchip: drop GRF dependency for rk3328/rk3036 pll types The rk3036/rk3328 pll types were converted to checking the lock status via the internal register in january 2020, so don't need the grf reference since then. But it was forgotten to remove grf check when deciding between the pll rate ops (read-only vs. read-write), so a clock driver without the needed grf reference might've been put into the read-only mode just because the grf reference was missing. This affected the rk356x that needs to reclock certain plls at boot. Fix this by removing the check for the grf for selecting the utilized operations.
