From: Manivannan Sadhasivam Date: Thu, 28 Feb 2019 15:45:11 +0000 (+0530) Subject: arm64: dts: hisilicon: hikey970: Add SD and WiFi support X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1761101048a3144bf141359b15a6132c3d3cc001;p=linux.git arm64: dts: hisilicon: hikey970: Add SD and WiFi support Add SD and WiFi support for HiKey970 board based on HI3670 SoC. Due to the absence of the PMIC driver, fixed regulators are sourced to make the driver working.
