This avoids the need to look up the masks each time an interrupt
is handled.

Provide separate interrupt handlers which may be used by platforms where
SDHI has three interrupt sources.
This patch also removes the commented-out handling of CRC and other errors.

Make use of per-source irq handles if the

The SDHI driver already supports making use of up to three interrupt

This series breaks up the existing interrupt handler into three handlers,
one for card access, one for card detect interrupts, and one for SDIO
interrupts. A cover-all handler, which makes use of these new broken-out

Hi
In eMMC spec, if set BKOPS_SUPPORT bit in ext_csd,
BKOPS_EN, BKOPS_STATUS, BKOPS_START and URGENT_BKOPS are supported for default.
So need not to send switch-command for BKOPS_EN when set BKOPS_SUPPORT bit.
Thanks,
