clk: imx: imx8mp: fix a53 cpu clock
The A53 CCM clk root only accepts input up to 1GHz, CCM A53 root signoff timing is 1Ghz, however the A53 core which sources from CCM root could run above 1GHz which voilates the CCM. There is a CORE_SEL slice before A53 core, we need configure the CORE_SEL slice source from ARM PLL, not A53 CCM clk root. The A53 CCM clk root should only be used when need to change ARM PLL frequency. Add arm_a53_core clk that could source from arm_a53_div and arm_pll_out. Configure a53 ccm root sources from 800MHz sys pll Configure a53 core sources from arm_pll_out Mark arm_a53_core as critical clk Reviewed-by: Jacky Bai <ping.bai@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
