Hi, I am having issues with this patch (commit id:-785b215250310c690142abb1bdbb0767b8487c49 " mmc: sdhi: use maximum width for the sdbuf register") I am testing SDHI1 against linux-next-20170727 tag with iWave RZ/G1M board which is identical to R-Car M2. Getting below SDHI1 errors during boot. This issue is fixed by reverting this patch.
