Please discard this series. I want to upport another BSP fix, but I need
all patches in a specific order to ease backporting. I'll send a new
series on Monday latest.
This small series upports a BSP improvement in a refactored way. The original patch 15d7abbfc3f0 ("mmc: renesas_sdhi: reset calibration register") added a new quirk for devices which always should disable HS400 adjustment. This was only applicable for SoCs which either had bad_taps or needed a calibration table. So, I simply used this logic directly. This is patch 2. To achieve this in a readable way, I finally did something I wanted to do for some time now. Having a helper to check for SDHI quirks. This is patch 1. The series has been tested on a Salvator-XS (R-Car M3-N). The patches are based on mmc/next as of today as they depend on d901e2ba566 ("mmc: renesas_sdhi: take DMA end interrupts into account"). Let me know what you think!
