From: Aapo Vienamo Date: Thu, 30 Aug 2018 15:06:25 +0000 (+0300) Subject: mmc: tegra: Remove tegra_sdhci_writew() from tegra210_sdhci_ops X-Git-Tag: v5.15~7810^2~82 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f6a447fafa39c9a25c83c5dafae499e08be2eb51;p=platform%2Fkernel%2Flinux-starfive.git mmc: tegra: Remove tegra_sdhci_writew() from tegra210_sdhci_ops tegra_sdhci_writew() defers the write to SDHCI_TRANSFER_MODE until SDHCI_COMMAND is written. This is not necessary on Tegra210 and Tegra186 and it breaks read-modify-write operations on SDHCI_TRANSFER_MODE because writes to SDHCI_TRANSFER_MODE aren't visible until SDHCI_COMMAND has been written to. This results in tuning failures on Tegra210.
