Subject: [PATCH 2/4] soc: qcom: rpmpd: Add corner power-domains states
Date: Fri,  5 Aug 2022 15:49:33 +0800	[thread overview]
Message-ID: <20220805074935.1158098-3-jun.nie@linaro.org> (raw)
In-Reply-To: <20220805074935.1158098-1-jun.nie@linaro.org>

Some SoCs use corner instead of level in rpm regulator, such as
MSM8916 and MSM8939. Add these power-domains states value so that
devices can vote them.

Note that there is a shift with 1 when converting the value from
regulator usage in Qualcomm Linux 3.18 to power domain usage here.
Because corner is not well hacked in regulator framework in 3.18.
For example, RPM_REGULATOR_CORNER_RETENTION is 2 in 3.18 while
RPM_SMD_CORNER_RETENTION is 1.
