    Subject[PATCH 5.10 245/563] clk: imx8mn: Fix imx8mn_clko1_sels
    From: Adam Ford <>

    [ Upstream commit 570727e9acfac1c2330a01dd5e1272e9c3acec08 ]

    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.

    Fixes: 96d6392b54db ("clk: imx: Add support for i.MX8MN clock driver")
