Subject: [PATCH V2 04/10] clk: imx8mp: Define gates for pll1/2 fixed dividers
From: Peng Fan <peng.fan@....com>
Inspried from
commit e8688fe8df7d ("clk: imx8mn: Define gates for pll1/2 fixed dividers")
On imx8mp there are 9 fixed-factor dividers for SYS_PLL1 and SYS_PLL2
each with their own gate. Only one of these gates (the one "dividing" by
one) is currently defined and it's incorrectly set as the parent of all
the fixed-factor dividers.
Add the other 8 gates to the clock tree between sys_pll1/2_bypass and
the fixed dividers.
