Subject: [PATCH 2/4] cpuidle: big.LITTLE: enable driver only on Peach-Pit/Pi Chromebooks
Date: Tue, 16 Jun 2020 10:12:28 +0200 [thread overview]
Message-ID: <20200616081230.31198-3-m.szyprowski@samsung.com> (raw)
In-Reply-To: <20200616081230.31198-1-m.szyprowski@samsung.com>
This driver always worked properly only on the Exynos 5420/5800 based
Chromebooks (Peach-Pit/Pi), so change the required compatible string to
the 'google,peach', to avoid enabling it on the other Exynos 542x/5800
boards, which hangs in such case. The main difference between Peach-Pit/Pi
and other Exynos 542x/5800 boards is the firmware - Peach platform doesn't
use secure firmware at all.
