Subject: [PATCH] cpufreq: fix compile-test defaults
Date: Wed, 16 Apr 2025 15:43:31 +0200	[thread overview]
Message-ID: <20250416134331.7604-1-johan+linaro@kernel.org> (raw)

Commit 3f66425a4fc8 ("cpufreq: Enable COMPILE_TEST on Arm drivers")
enabled compile testing of most Arm CPUFreq drivers but left the
existing default values unchanged so that many drivers are enabled by
default whenever COMPILE_TEST is selected.

This specifically results in the S3C64XX CPUFreq driver being enabled
and initialised during boot of non-S3C64XX platforms with the following
error logged:

	cpufreq: Unable to obtain ARMCLK: -2

Fix the default values for drivers that can be compile tested and that
should be enabled by default when not compile testing.

Fixes: 3f66425a4fc8 ("cpufreq: Enable COMPILE_TEST on Arm drivers")
