ARM: Orion: fix driver probe error handling with respect to clk

2012-07-25T15:06:21Z

The clk patches added code to get and enable clocks in the respective driver probe functions. If the probe function failed for some reason after enabling the clock, the clock was not disabled again in many cases. Signed-off-by: Simon Baatz Signed-off-by: Andrew Lumm

ARM: Orion: SDIO: Add support for clk.

2012-05-08T23:34:00Z

Some orion devices can gate the SDIO clock. If the clock exists, enable/disable it as appropriate. Signed-off-by: Andrew Lunn Tested-by: Jamie Lentin Signed-off-by: Mike Turquette

ARM: Orion: Get address map from plat-orion instead of via platform_data

2011-12-13T23:46:55Z

Use an getter function in plat-orion/addr-map.c to get the address map structure, rather than pass it to drivers in the platform_data structures. When the drivers are built for none orion platforms, a dummy function is provided instead which returns NULL.

mmc: replace printk with appropriate display macro

2011-10-26T20:32:22Z

All the files using printk function for displaying kernel messages in the mmc driver have been replaced with corresponding macro. Signed-off-by: Girish K S Signed-off-by: Chris Ball

mmc: Remove distinction between hw and phys segments

2010-10-23T13:11:11Z

We have deprecated the distinction between hardware and physical segments in the block layer. Consolidate the two limits into one in drivers/mmc/. Signed-off-by: Martin K. Petersen Signed-off-by: Chris Ball

mmc: remove the "state" argument to mmc_suspend_host()

2010-05-27T16:12:40Z

Even though many mmc host drivers pass a pm_message_t argument to mmc_suspend_host() that argument isn't used the by MMC core. As host drivers are converted to dev_pm_ops they'll have to construct pm_message_t's (as they won't be passed by the PM subsystem any more) just to appease the mmc suspend interface. We might as well just delete the unused paramter.

mvsdio: fix handling of partial word at the end of PIO transfer

2009-07-20T23:46:34Z

Standard data flow for MMC/SD/SDIO cards requires that the mvsdio controller be set for big endian operation. This is causing problems with buffers which length is not a multiple of 4 bytes as the last partial word doesn't get shifted all the way and stored properly in memory. Let's compensate for this.

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.
