mmc: cavium: Add core MMC driver for Cavium SOCs2017-04-24T19:42:09ZJan Glauberjglauber@cavium.com2017-03-30T15:31:24Zurn:sha1:ba3869ff32e4a671b0f9baa73900f9e2bfeb0414
This core driver will be used by a MIPS platform driver
or by an ARM64 PCI driver. The core driver implements the
mmc_host_ops and slot probe & remove functions.
Callbacks are provided to allow platform specific interrupt
enable and bus locking.
The host controller supports:
- up to 4 slots that can contain sd-cards or eMMC chips
- 1, 4 and 8 bit bus width
- SDR and DDR
- transfers up to 52 Mhz (might be less when multiple slots are used)
- DMA read/write
- multi-block read/write (but not stream mode)
Voltage is limited to 3.3v and shared for all slots (vmmc and vmmcq).
A global lock for all MMC devices is required because the host
controller is shared.
