sdhci-of: Fix the wrong accessor to HOSTVER register

2009-06-03T19:56:22Z

Freescale eSDHC controller has the special order for the HOST version register. that is not same as the other's registers. The address of HOSTVER in spec is 0xFE, and we need use the in_be16(0xFE) to access it, not in_be16(0xFC). Signed-off-by: Dave Liu Acked-by: Anton Vorontsov Signed-off-by: Pierre Ossman

mvsdio: fix config failure with some high speed SDHC cards

2009-06-03T19:51:00Z

Especially with Sandisk SDHC cards, the second SWITCH command was failing with a timeout and the card was not recognized at all. However if the system was busy, or debugging was enabled, or a udelay(100) was inserted before the second SWITCH command in the core code, then the timing was so that the card started to work. With some unusual block sizes, the data FIFO status doesn't indicate a "empty" state right away when the data transfer is done. Queuing another data transfer in that condition results in a transfer timeout. The empty FIFO bit eventually get set by itself in less than 50 usecs when it is not set right away. So let's just poll for that bit before configuring the controller with a new data transfer. Signed-off-by: Nicolas Pitre Signed-off-by: Pierre Ossman

mvsdio: ignore high speed timing requests from the core

2009-06-03T19:50:33Z

Empirical evidences show that this is causing far more problems than it solves when this mode is enabled in the host hardware. Amongst those cards that are known to be non functional when this bit is set are: A-Data "Speedy" 2GB SD card Kodak 512MB SD card Ativa 1GB MicroSD card Marvell 8688 (WIFI/Bluetooth) SDIO card Since those cards do work on other host controllers which do honnor the hs timing, the issue must be with this particular host hardware.

mmc/omap: Use disable_irq_nosync() from within irq handlers.

2009-06-03T19:50:23Z

disable_irq() should wait for all running handlers to complete before returning. As such, if it's used to disable an interrupt from that interrupt's handler it will deadlock. This replaces the dangerous instances with the _nosync() variant which doesn't have this problem. Signed-off-by: Ben Nizette Acked-by: Tony Lindgren Signed-off-by: Pierre Ossman

sdhci-of: Add fsl,esdhc as a valid compatible to bind against

2009-06-03T19:49:55Z

We plan to use fsl,esdhc going forward as the base compatible so update the driver to bind against it. Signed-off-by: Kumar Gala Signed-off-by: Pierre Ossman

mxcmmc : Reset the SDHC hardware if software timeout occurs.

2009-06-03T19:48:17Z

When a software timeout occurs in polling mode hardware was left in an indeterminate state causing subsequent operations to block. Signed-off-by: Martin Fuzzey
