[PATCH] clk: qcom: gcc-ipq6018: mark gcc_xo_clk_src as critical

From: Christian Marangi

Date: Wed Mar 11 2026 - 14:22:01 EST


From: John Crispin <john@xxxxxxxxxxx>

The XO clock source is always-on in hardware and cannot be gated.
Without CLK_IS_CRITICAL, runtime PM of downstream consumers (such as
the CMN PLL driver) cascades a disable up to gcc_xo_clk_src, causing
a branch status timeout warning.

The IPQ8074 GCC driver already marks this clock as CLK_IS_CRITICAL.
Apply the same fix to IPQ6018.
