From: Karel Balej Date: Mon, 10 Mar 2025 14:07:04 +0000 (+0100) Subject: mmc: sdhci-pxav3: set NEED_RSP_BUSY capability X-Git-Tag: v6.15-rc1~178^2~6 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a41fcca4b342811b473bbaa4b44f1d34d87fcce6;p=thirdparty%2Fkernel%2Flinux.git mmc: sdhci-pxav3: set NEED_RSP_BUSY capability Set the MMC_CAP_NEED_RSP_BUSY capability for the sdhci-pxav3 host to prevent conversion of R1B responses to R1. Without this, the eMMC card in the samsung,coreprimevelte smartphone using the Marvell PXA1908 SoC with this mmc host doesn't probe with the ETIMEDOUT error originating in __mmc_poll_for_busy. Note that the other issues reported for this phone and host, namely floods of "Tuning failed, falling back to fixed sampling clock" dmesg messages for the eMMC and unstable SDIO are not mitigated by this change.
