Subject: [PATCH AUTOSEL 5.4 02/19] arm64: dts: qcom: sdm845: Reserve LPASS clocks in gcc
Date: Mon, 8 Feb 2021 12:58:41 -0500 [thread overview]
Message-ID: <20210208175858.2092008-2-sashal@kernel.org> (raw)
In-Reply-To: <20210208175858.2092008-1-sashal@kernel.org>
From: Bjorn Andersson <bjorn.andersson@linaro.org>
[ Upstream commit 93f2a11580a9732c1d90f9e01a7e9facc825658f ]
The GCC_LPASS_Q6_AXI_CLK and GCC_LPASS_SWAY_CLK clocks may not be
touched on a typical UEFI based SDM845 device, but when the kernel is
built with CONFIG_SDM_LPASSCC_845 this happens, unless they are marked
as protected-clocks in the DT.
This was done for the MTP and the Pocophone, but not for DB845c and the
Lenovo Yoga C630 - causing these to fail to boot if the LPASS clock
controller is enabled (which it typically isn't).
