Good morning, > - Requesting a test of this on i.MX. (Sorry Benjamin.) No worries. I did another test with your v5 patch, but it doesn't work. Here is the kernel log: sdhci: Secure Digital Host Controller Interface driver sdhci: Copyright(c) Pierre Ossman sdhci-pltfm: SDHCI platform and OF driver helper sdhci-esdhc-imx 53fb4000.esdhc: host only supports SDMA, activate bounce buffer sdhci-esdhc-imx 53fb4000.esdhc: bounce buffer: bounce up to 128 segments into one, max segment size 65536 bytes mmc0: SDHCI controller on 53fb4000.esdhc [53fb4000.esdhc] using DMA sdhci-esdhc-imx 53fb8000.esdhc: Got CD GPIO sdhci-esdhc-imx 53fb8000.esdhc: Got WP GPIO sdhci-esdhc-imx 53fb8000.esdhc: host only supports SDMA, activate bounce buffer sdhci-esdhc-imx 53fb8000.esdhc: bounce buffer: bounce up to 128 segments into one, max segment size 65536 bytes mmc1: SDHCI controller on 53fb8000.esdhc [53fb8000.esdhc] using DMA mmc0: new high speed MMC card at address 0001 oprofile: no performance counters oprofile: using timer interrupt. mmcblk0: mmc0:0001 002G00 1.83 GiB mmcblk0boot0: mmc0:0001 002G00 partition 1 512 KiB NET: Registered protocol family 10 mmcblk0boot1: mmc0:0001 002G00 partition 2 512 KiB Segment Routing with IPv6 sit: IPv6, IPv4 and MPLS over IPv4 tunneling driver NET: Registered protocol family 17 can: controller area network core (rev 20170425 abi 9) NET: Registered protocol family 29 can: raw protocol (rev 20170425) can: broadcast manager protocol (rev 20170425 t) can: netlink gateway (rev 20170425) max_hops=1 input: gpio-keys as /devices/platform/gpio-keys/input/input1 mmcblk0rpmb: mmc0:0001 002G00 partition 3 128 KiB imxdi_rtc 53ffc000.dryice: setting system clock to 1970-01-05 20:50:24 UTC (420624) mmcblk0: p1 p2 p3 p4 < p5 p6 p7 p8 p9 p10 > EXT4-fs (mmcblk0p8): couldn't mount as ext3 due to feature incompatibilities EXT4-fs (mmcblk0p8): couldn't mount as ext2 due to feature incompatibilities EXT4-fs (mmcblk0p8): INFO: recovery required on readonly filesystem EXT4-fs (mmcblk0p8): write access will be enabled during recovery EXT4-fs (mmcblk0p8): recovery complete EXT4-fs (mmcblk0p8): mounted filesystem with ordered data mode.
