I have queued up the following, And I will push it either in the next half hour or some time next week - I have to jump on a plane shortly. Guennadi, it seems that SDHI (and MMCIF) support form armadillo800eva-reference never made it into my tree. And I have dropped r8a7740.dtsi changes from the patch below accordingly. Would you care to repost that series with the compatibility string updated? From: Guennadi Liakhovetski [PATCH] ARM: shmobile: update SDHI DT compatibility string to the - format Currently DT compatibility strings of both types can be found in the kernel sources: - and -, whereas a unique format should be followed and the former one is preferred. This patch converts the SDHI MMC driver and its users to the common standard. This is safe for now, since ATM no real products are using this driver with DT.
