Subject: [PATCH 8/8] dts: hisilicon: add support for the PMIC found on Hikey 970
Date: Mon, 16 Nov 2020 13:59:34 +0100 [thread overview]
Message-ID: <eb5250f1bb0d19efe2d3e48ba08f5f1a6613e175.1605530560.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1605530560.git.mchehab+huawei@kernel.org>
Add a device tree for the HiSilicon 6421v600 SPMI PMIC, used
on HiKey970 board.
As we now have support for it, change the fixed regulators
used by the SD I/O to use the proper LDO supplies.
