Subject: [PATCH 48/70] mmc: sdhci-of-esdhc: add/remove some quirks according
to vendor version
commit 6c42cb309fee2e126beed6b96a986dc7d85a033d
[context adjustment]
A previous patch had removed esdhc_of_platform_init() by mistake.
static void esdhc_of_platform_init(struct sdhci_host *host)
{
u32 vvn;
vvn = in_be32(host->ioaddr + SDHCI_SLOT_INT_STATUS);
vvn = (vvn & SDHCI_VENDOR_VER_MASK) >> SDHCI_VENDOR_VER_SHIFT;
if (vvn == VENDOR_V_22)
host->quirks2 |= SDHCI_QUIRK2_HOST_NO_CMD23;
if (vvn > VENDOR_V_22)
host->quirks &= ~SDHCI_QUIRK_NO_BUSY_IRQ;
}
This patch is used to fix it by add/remove some quirks according to
verdor version in probe.
