[PATCH 3/5] clk: qcom: dispcc-milos: Fix DSI byte clock rate setting
From: Konrad Dybcio
Date: Wed Mar 04 2026 - 08:55:45 EST
From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>
The clock tree for byte_clk_src is as follows:
┌──────byte0_clk_src─────┐
│ │
byte0_clk byte0_div_clk_src
│
byte0_intf_clk
If both of its direct children have CLK_SET_RATE_PARENT with different
requests, byte0_clk_src (and its parent) will be reconfigured. In this
case, byte0_intf should strictly follow the rate of byte0_clk (with
some adjustments based on PHY mode).
Remove CLK_SET_RATE_PARENT from byte0_div_clk_src to avoid this issue.
Fixes: f40b5217dce1 ("clk: qcom: Add Display Clock controller (DISPCC) driver for Milos")
