[PATCH] clk: imx8mn: Fix imx8mn_clko1_sels
From: Adam Ford <hidden>
Date: 2021-11-17 13:32:14
When attempting to use sys_pll1_80m as the parent for clko1, the
system hangs. This is due to the fact that the source select
for sys_pll1_80m was incorrectly pointing to m7_alt_pll_clk, which
doesn't yet exist.
According to Rev 3 of the TRM, The imx8mn_clko1_sels also incorrectly
references an osc_27m which does not exist, nor does an entry for
source select bits 010b. Fix both by inserting a dummy clock into
the missing space in the table and renaming the incorrectly name clock
with dummy.
