Subject: [PATCH v2 1/5] cpuidle: psci: Split into two separate build objects
Date: Tue,  7 Jul 2020 14:58:00 +0200	[thread overview]
Message-ID: <20200707125804.13030-2-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20200707125804.13030-1-ulf.hansson@linaro.org>

The combined build object for the PSCI cpuidle driver and the PSCI PM
domain, is a bit messy. Therefore let's split it up by adding a new Kconfig
ARM_PSCI_CPUIDLE_DOMAIN and convert into two separate objects.
