Subject: [PATCH] ARM: dts: qcom: ipq8064: disable mmc-ddr-1_8v for sdcc1
Date: Tue, 25 Oct 2022 01:38:17 +0200 [thread overview]
Message-ID: <20221024233817.27410-1-ansuelsmth@gmail.com> (raw)
It was reported non working mmc with this option enabled.
Both mmc for ipq8064 are supplied by a fixed 3.3v regulator so mmc can't
be run at 1.8v.
Disable it to restore correct functionality of this SoC feature.
Tested-by: Hendrik Koerner <koerhen@web.de>
