Subject: [PATCH 5/8] soc: qcom: geni: Add support for ACPI
Date: Tue, 4 Jun 2019 11:44:52 +0100 [thread overview]
Message-ID: <20190604104455.8877-5-lee.jones@linaro.org> (raw)
In-Reply-To: <20190604104455.8877-1-lee.jones@linaro.org>
When booting with ACPI as the active set of configuration tables,
all; clocks, regulators, pin functions ect are expected to be at
their ideal values/levels/rates, thus the associated frameworks
are unavailable. Ensure calls to these APIs are shielded when
ACPI is enabled.
