sdhci: Add NO_BUSY_IRQ quirk for Marvell CAFE host chip

2009-03-17T00:32:29+00:00

commit a0874897b1ba106298e4303a25456a473fc40f3d upstream.

As described here: http://lkml.org/lkml/2009/2/20/265

The CAFE chip is broken due to commit e809517f6fa5803a5a1cd5602.
Anton added a quirk here: http://lkml.org/lkml/2009/2/20/279 that fixes
CAFE's problem.  This adds the quirk for CAFE.

sdhci: Add quirk for controllers with no end-of-busy IRQ

2009-03-17T00:32:28+00:00

commit f945405cdecd9e0ae3e58ff84cabd19b4522965e upstream.

The Samsung SDHCI (and FSL eSDHC) controller block seems to fail
to generate an INT_DATA_END after the transfer has completed and
the bus busy state finished.

Changes in e809517f6fa5803a5a1cd56026f0e2190fc13d5c to use the
new busy method are the cause of the behaviour change.

mmc_test: fix basic read test

2009-03-17T00:32:20+00:00

commit 58a5dd3e0e77029d3db1f8fa75d0b54b38169d5d upstream.

Due to a typo in the Basic Read test, it's currently identical to the
Basic Write test.  Fix this.

mmc: s3cmci: fix s3c2410_dma_config() arguments.

2009-03-17T00:32:20+00:00

commit 7c48ed3383bfb2106694807361ec187fe8a4333d upstream.

The s3cmci driver is calling s3c2410_dma_config with incorrect data for
the DCON register.  The S3C2410_DCON_HWTRIG is implicit in the channel
configuration and the device selection of S3C2410_DCON_CH0_SDI is
incorrect as the DMA system may not select channel 0.

s3cmci: Fix hangup in do_pio_write()

2009-03-17T00:32:20+00:00

commit 994244883739e4044bef76d4e5d7a9b66dc6c7b6 upstream.

This commit fixes the regression what was added by commit
088a78af978d0c8e339071a9b2bca1f4cb368f30 "s3cmci: Support transfers
which are not multiple of 32 bits."

fifo_free() now returns amount of available space in FIFO buffer in
bytes.  But do_pio_write() writes to FIFO 32-bit words.  Condition for
return from cycle is (fifo_free() == 0), but when fifo has 1..3 bytes
of free space then this condition will never be true and system hangs.

This patch changes condition in the while() to (fifo_free() > 3).

mmc: fix data timeout for SEND_EXT_CSD

2009-03-17T00:32:19+00:00

commit cda56ac29f2d8288d62978272856884d26e0b47b upstream.

Commit 0d3e0460f307e84904968aad6cff97bd688583d8
"MMC: CSD and CID timeout values" inadvertently broke
the timeout for the MMC command SEND_EXT_CSD.

This patch puts it back again.

Depending on the characteristics of the controller,
this bug may prevent the use of MMC cards.

sdhci: fix led naming

2009-03-17T00:32:17+00:00

commit 5dbace0c9ba110c1a3810a89fa6bf12b7574b5a3 upstream.

Fix the led device naming for the sdhci driver.

The led class documentation defines the led name to have the
form "devicename:colour:function" while not applicable sections
should be left blank.

To comply with the documentation the led device name is changed
from "mmc*" to "mmc*::".

mmc: increase SD write timeout for crappy cards

2008-11-08T20:36:59+00:00

It seems that some cards are slightly out of spec and occasionally
will not be able to complete a write in the alloted 250 ms [1].
Incease the timeout slightly to allow even these cards to function
properly.
