[PATCH 10/48] clk: qcom: dispcc-sm8250: Use common probe handling for always-on clocks

From: Abel Vesa

Date: Wed Sep 16 2026 - 07:03:10 EST


Describe the always-on branches in a critical_cbcrs array and reference
it through qcom_cc_driver_data. Let qcom_cc_really_probe() enable these
branches instead of programming them directly in the driver's probe.
