From: yangbo lu yangbo.lu@freescale.com
commit 1ef5e49e46b919052474d9b54a15debc79ff0133 upstream.
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.
