Subject: [PATCH 3/3] arm64: dts: rockchip: fix RockPro64 sdmmc settings
Date: Thu, 3 Oct 2019 23:50:36 +0200 [thread overview]
Message-ID: <20191003215036.15023-3-smoch@web.de> (raw)
In-Reply-To: <20191003215036.15023-1-smoch@web.de>
According to the RockPro64 schematic [1] the rk3399 sdmmc controller is
connected to a microSD (TF card) slot, which cannot be switched to 1.8V.
So also configure the vcc_sdio regulator, which drives the i/o voltage
of the sdmmc controller, accordingly.
While at it, also remove the cap-mmc-highspeed property of the sdmmc
controller, since no mmc card can be connected here.
