#1240094 — [PATCH 1/8] mmc: sdhci-pxav3: remove broken clock base quirk for Armada 38x sdhci driver

From: Nadav Haklai <nadavh@marvell.com>

shci-pxav3 driver is enabling by default the
SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN quirk. However this quirk is not
required for Armada 38x and leads to wrong clock setting in the divider.
