Subject: [PATCH v4 2/9] soc: qcom: rpmpd: Add support to set rpmpd state to max
Date: Mon, 13 May 2019 15:50:08 +0530
Message-ID: <20190513102015.26551-3-sibis@codeaurora.org> (raw)
In-Reply-To: <20190513102015.26551-1-sibis@codeaurora.org>

rpmpd max state varies across SoCs and SoC families, add support
in the driver to make it SoC/SoC family specific
