Subject: [PATCH v3 0/2] mmc: sdhci-pxav3: pinctrl setting for fast bus
 clocks

Hello,

This small series adds a pinctrl setting for fast MMC bus clocks to the
pxav3 driver. On bus clocks above 100 MHz, driving the data pins at a
higher current helps maintain signal quality.

This series is related to Marvell PXA1908 SoC support; the latest
version of that patchset (v16 as of now) can be found at
https://lore.kernel.org/20250708-pxa1908-lkml-v16-0-b4392c484180@dujemihanovic.xyz
