Subject: [PATCH v2 1/9] clk: qcom: gcc-sdm660: Mark MMSS NoC CFG AHB clock as critical
Date: Wed, 13 Jan 2021 19:38:09 +0100 [thread overview]
Message-ID: <20210113183817.447866-2-angelogioacchino.delregno@somainline.org> (raw)
In-Reply-To: <20210113183817.447866-1-angelogioacchino.delregno@somainline.org>
Similarly to MSM8998, any access to the MMSS depends on this clock.
Gating it will crash the system when RPMCC inits mmssnoc_axi_rpm_clk.
