Subject: [PATCH] clk: rockchip: fix rk3568 cpll clk gate bits
Date: Wed, 19 May 2021 13:41:49 -0400	[thread overview]
Message-ID: <20210519174149.3691335-1-pgwipeout@gmail.com> (raw)

The cpll clk gate bits had an ordering issue. This led to the loss of
the boot sdmmc controller when the gmac was shut down with:
`ip link set eth0 down`
as the cpll_100m was shut off instead of the cpll_62p5.
cpll_62p5, cpll_50m, cpll_25m were all off by one with cpll_100m
misplaced.

Fixes: cf911d89c4c5 ("clk: rockchip: add clock controller for rk3568")
