mmc: sdhci: Wait for SDHCI_INT_DATA_END when transferring.

2017-04-14T06:23:14+00:00

sdhci_transfer_data() function transfers the blocks passed up to the
number of blocks defined in mmc_data, but returns immediately once all
the blocks are transferred, even if the loop exit condition is not met
(bit SDHCI_INT_DATA_END set in the STATUS word).

When doing multiple writes to mmc, returning right after the last block
is transferred can cause the write to fail when sending the
MMC_CMD_STOP_TRANSMISSION command right after the
MMC_CMD_WRITE_MULTIPLE_BLOCK command, leaving the mmc driver in an
unconsistent state until reboot. This error was observed in the rpi3
board.

This patch waits for the SDHCI_INT_DATA_END bit to be set even after
sending all the blocks.

Test: Reliably wrote 2GiB of data to mmc in a rpi3.

mmc: bcm2835_sdhci: Speed up mmc writes.

2017-04-14T06:23:03+00:00

The linux kernel driver for this module does not use a delay when
writing to the SDHCI_BUFFER register. This patch mimics that behavior
in order to speed up the mmc writes on the Raspberry Pi.

dm: core: Add flags parameter to device_remove()

2017-04-05T02:15:10+00:00

This patch adds the flags parameter to device_remove() and changes all
calls to this function to provide the default value of DM_REMOVE_NORMAL
for "normal" device removal.

This is in preparation for the driver specific pre-OS (e.g. DMA
cancelling) remove support.
