From 81bbd2bd24a9ebac3871b293060df50445458c79 Mon Sep 17 00:00:00 2001 From: Vyacheslav Bocharov Date: Sat, 26 Mar 2022 10:51:09 +0300 Subject: [PATCH] arm64: meson: update SDIO voltage in dts for JetHub D1 Fix the dts to match board's reference design: - update vddio_boot regulator to 3.3v (Wi-Fi SDIO module) - add vccq_1v8 regulator with 1.8v for eMMC SDIO In the first revision of JetHub D1 the vccq_1v8 regulator was 3.3v. All installed eMMC modules were tested to work in HS200 mode at 3.3v supply voltage. In the next revisions of the board eMMC will be powered with 1.8v according to the standard.
