Subject: [PATCH V2 4/6] regulator: qcom_smd: Add MP5496 regulators
Date: Tue, 23 Jun 2020 10:47:50 +0530	[thread overview]
Message-ID: <1592889472-6843-5-git-send-email-kathirav@codeaurora.org> (raw)
In-Reply-To: <1592889472-6843-1-git-send-email-kathirav@codeaurora.org>

IPQ6018 SoC uses the PMIC MP5496. SMPA2 and LDOA2 regulator controls the
APSS and SDCC voltage scaling respectively. Add support for the same.
