Subject: [PATCH v2] clk: meson: meson8b: Use CLK_SET_RATE_NO_REPARENT for vclk{,2}_in_sel
Date:   Mon, 24 May 2021 15:45:17 +0200

Precedence: bulk

Use CLK_SET_RATE_NO_REPARENT for the vclk{,2}_in_sel clocks. The only
parent which is actually used is vid_pll_final_div. This should be set
using assigned-clock-parents in the .dts rather than removing some
"unwanted" clock parents from the clock driver.

After a hint from Jerome (thanks) this is the improved version of
"clk: meson: meson8b: Don't use MPLL1 as parent of vclk_in_sel" from [0]
