2010-02-15omap_hsmmc: allow compile without regulator frameworkAdrian Hunter1-54/+79
It is still possible to use the omap_hsmmc module without the regulator framework. Accordingly, ifdef out regulator-specific functions. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2010-02-15omap_hsmmc: Allow for a shared VccQAdrian Hunter1-1/+15
EMMC can have two voltage supplies, Vcc and VccQ which are implemented in the code as consumer supplies vmmc and vmmc_aux. If the regulator that supplies vmmc_aux is shared with other consumers, then sending it to sleep will disrupt those consumers. However, the TWL4030-family regulators may have OFF remapped to SLEEP, in which case 'regulator_disable()' will put the regulator to sleep only when all consumers are disabled - which is the desired behaviour. This patch adds a platform data field to allow that option. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2010-02-15omap_hsmmc: Move gpio and regulator control from board fileAdrian Hunter1-13/+339
This patch moves the setup code for GPIO's and Voltage Regulators from the board file mmc-twl4030.c to the driver omap_hsmmc.c. PBIAS and other system control configuration remains in the board file. Moving GPIO code to the driver makes the board initialisation code independent of when GPIO's are defined. That makes the board initialisation now entirely independent of its original twl4030 roots. Moving Voltage Regulator code to the driver allows for further development of regulator support in the core MMC code. It also permits the MMC core to be compiled as a module, because the board code no longer calls MMC core functions.

2010-02-11mmc_test: block addressed cardsJohan Kristell1-3/+6
This patch fixes a bug in the multiblock write tests where the written data is read back for verifying one block at a time. The tests in mmc_test assumes that all cards are byte addressable. This will cause the multi block write tests to fail, leading the user of the mmc_test driver thinking there is something wrong with the sdhci driver they are testing. The start address for the block is calculated as: blocknum * 512. For block addressable cards the blocknum alone should be used.

2010-01-11mmc_block: fix queue cleanupAdrian Hunter2-9/+11
The main bug was that 'blk_cleanup_queue()' was called while the block device could still be in use, for example, because the card was removed while files were still open. In addition, to be sure that 'mmc_request()' will get called for all new requests (so it can error them out), the queue is emptied during cleanup. This is done after the worker thread is stopped to avoid racing with it. Finally, it is not a device error for this to be happening, so quiet the (sometimes very many) error messages.

2010-01-11mmc_block: add dev_t initialization checkAnna Lemehova1-0/+5
When a card is removed before mmc_blk_probe() has called add_disk(), then the minor field is uninitialized and has value 0. This caused mmc_blk_put() to always release devidx 0 even if 0 was still in use. Then the next mmc_blk_probe() used the first free idx of 0, which oopses in sysfs, since it is used by another card.

2009-12-15mmc: atmel-mci: new MCI2 module support in atmel-mci driverNicolas Ferre1-10/+75
This new revision of the IP adds some improvements to the MCI already present in several Atmel SOC. Some new registers are added and a particular way of handling DMA interaction lead to a new sequence in function call which is backward compatible: On MCI2, we must set the DMAEN bit to enable the DMA handshaking interface. This must happen before the data transfer command is sent. A new function is able to differentiate MCI2 code and is based on knowledge of processor id (cpu_is_xxx()).

2009-12-15mmc: add module parameter to set whether cards are assumed removableBen Hutchings5-43/+23
Some people run general-purpose distribution kernels on netbooks with a card that is physically non-removable or logically non-removable (e.g. used for /home) and cannot be cleanly unmounted during suspend. Add a module parameter to set whether cards are assumed removable or non-removable, with the default set by CONFIG_MMC_UNSAFE_RESUME. In general, it is not possible to tell whether a card present in an MMC slot after resume is the same that was there before suspend. So there are two possible behaviours, each of which will cause data loss in some cases: CONFIG_MMC_UNSAFE_RESUME=n (default): Cards are assumed to be removed during suspend. Any filesystem on them must be unmounted before suspend; otherwise, buffered writes will be lost. CONFIG_MMC_UNSAFE_RESUME=y: Cards are assumed to remain present during suspend. They must not be swapped during suspend; otherwise, buffered writes will be flushed to the wrong card. Currently the choice is made at compile time and this allows that to be overridden at module load time.
