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 [thread overview]
Message-ID: <20210524134517.687089-1-martin.blumenstingl@googlemail.com> (raw)
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.
Suggested-by: Jerome Brunet <jbrunet@baylibre.com>
