Subject: [PATCH 6/6] mmc: core: with mmc-hs400-1_8(2)v not add MMC_CAP2_HS200* to host->caps2
Date: Tue, 8 Dec 2020 14:18:39 +0800 [thread overview]
Message-ID: <20201208061839.21163-7-chris.ruehl@gtsys.com.hk> (raw)
In-Reply-To: <20201208061839.21163-1-chris.ruehl@gtsys.com.hk>
When set mmc-hs400-1_8(2)v in dts, hs200 capabilities are not checked
in the mmc logic. Thus cleanup and remove MMC_CAP2_HS200_1_8V_SDR /
MMC_CAP2_HS200_1_2V_SDR from host->caps2.
