Subject: [PATCH V4 5/6] dts: arm64: Enable onboard SDHCI on msm8992
Date: Fri, 27 Jan 2017 01:10:04 -0800 [thread overview]
Message-ID: <1485508205-1904-6-git-send-email-jeremymc@redhat.com> (raw)
In-Reply-To: <1485508205-1904-1-git-send-email-jeremymc@redhat.com>
This enables SDHCI on the Nexus 5X as well creates common smd_rpm node
which can be shared between both 5X and 6P as per HW design.
Given the lack of documentation, only downstream code was used as a reference
and it eludes to the fact that 8994-rpm-regulator is common between both msm8992
& msm8994. [ see msm.git branch: msm-angler-3.10-marshmallow-mr1, msm8992.dtsi]
At this early stage of development it makes sense for the 8994-rpm-regulator
to be common until data / documentation suggests otherwise.
