Subject: [PATCH v2 01/11] clk: qcom: ipq8074: drop the CLK_SET_RATE_PARENT flag from PLL clocks
Date: Thu, 14 Sep 2023 12:29:51 +0530 [thread overview]
Message-ID: <20230913-gpll_cleanup-v2-1-c8ceb1a37680@quicinc.com> (raw)
In-Reply-To: <20230913-gpll_cleanup-v2-0-c8ceb1a37680@quicinc.com>
GPLL, NSS crypto PLL clock rates are fixed and shouldn't be scaled based
on the request from dependent clocks. Doing so will result in the
unexpected behaviour. So drop the CLK_SET_RATE_PARENT flag from the PLL
clocks.
Cc: stable@vger.kernel.org
Fixes: b8e7e519625f ("clk: qcom: ipq8074: add remaining PLL’s")
Signed-off-by: Kathiravan Thirumoorthy <quic_kathirav@quicinc.com>

Changes in V2:
- Include the stable mailing list
- Keep the CLK_SET_RATE_PARENT in UBI32 PLL, looks like these
PLL rates can be changed. So don't drop the flag.
