Subject: clk: imx: clk-imx8mn Fix nand and spi clock parent
X-Git-Url: http://git.dujemihanovic.xyz/html/%7B%7B%20%28.OutputFormats.Get?a=commitdiff_plain;h=50cdd3f74af330c56713f7758d4ff1af9f3b7e72;p=u-boot.git

clk: imx: clk-imx8mn Fix nand and spi clock parent

The osc_24m is the clock-output-name and not the one that
is used as internal name reference from the strcmp. The clock
that use osc_24m, will not be able to reparent it as they should.
We need anyway register the osc_24m clock fixed factor in the clock
tree.

Fixes: 710c4ffb890 ("clk: imx: clk-imx8mn add gpmi nand clocks")
Fixes: 85b1c11989c ("clk: imx: Add ECSPI to iMX8MN")
