Subject: [PATCH 0/2] clk: qcom: gcc-sm8550: Fix shared clk parking breakage
Date: Mon, 19 Aug 2024 16:36:25 -0700	[thread overview]
Message-ID: <20240819233628.2074654-1-swboyd@chromium.org> (raw)

Amit Pundir reported[1] that a recent commit 01a0a6cc8cfd ("clk: qcom:
Park shared RCGs upon registration") broke USB and audio on sm8550-hdk.
These two patches fix the issue by skipping the parking bit of the
shared RCGs for devices that can't run so slow.

  clk: qcom: gcc-sm8550: Don't use parking clk_ops for QUPs
  clk: qcom: gcc-sm8550: Don't park the USB RCG at registration time
