[PATCH 07/11] sdhci: Add quirk to suppress PIO interrupts during DMA transfers

2009-02-06 Thread Anton Vorontsov
Some hosts (that is, FSL eSDHC) throw PIO interrupts during DMA transfers, this causes tons of unneeded interrupts, and thus highly degraded speed. This patch adds SDHCI_QUIRK_PIO_IRQS_DURING_DMA quirk. When specified, the sdhci driver will disable PIO interrupts during DMA transfers. Signed-off-
