2011-11-23usb : musb : Do not register musb core PM opsrajaram
Currently musb core PM ops does save and restore of context The platform can enter CPU idle before the platform or runtime suspend is called.But musb core PM ops is not aware of CPU idle. and thus it saves and restores some junk context Since junk context is restored there is instability in usb functions. ux500 USB platform file handles the save and restore properly during cable connect and disconnent.So we don't require handling of context save and restore in musb core and hence not registering musb core PM ops.

2011-10-27mmc: core: move ->request() call from atomic contextAdrian Hunter
mmc_request_done() is sometimes called from interrupt or other atomic context. Mostly all mmc_request_done() does is complete(), however it contains code to retry on error, which uses ->request(). As the error path is certainly not performance critical, this may be moved to the waiting function mmc_wait_for_req_done(). This allows ->request() to use runtime PM get_sync() and guarantee it is never in an atomic context.

2011-10-27regulators: ab8500: Add support of low voltage batteryBengt Jonsson
Low voltage batteries have a wider voltage range with lower operating voltages. Some consumers in the platform may not work with the lower voltages and therefore need an extra regulator to boost the voltage in this case. This driver adds support for checking the consumers that need higher voltage (Vaux1, 2 and 3 regulators, 3 V SIM) and control the external buck/boost regulator accordingly. Note that to utilize the low voltage battery support, the battery voltage thresholds must be changed. This applies for the low battery voltage threshold of the battery manager and the OTP setting for the AB8500 BattOk levels.

Stress-testing the runtime power management of libertas_sdio through a rmmod/insmod loop revealed that it is quite easy to cause an ETIMEDOUT failure in mmc_sdio_power_restore() leading to: libertas_sdio: probe of mmc1:0001:1 failed with error -16 Experimentation shows that a very short delay (100us) is needed in the power down path before the card can be successfully booted again. We know that this setup is lacking poweroff clamps on the card's power lines, but as only a short delay is needed, apply this unconditionally. Also bump up to 1ms sleep for extra legroom.

2011-10-27mmc: sd: UHS-I bus speed should be set last in UHS initializationSubhash Jadavani
mmc_sd_init_uhs_card function sets the driver type, current limit and bus speed mode on card as well as on host controller side. Currently bus speed mode is set by sending CMD6 to card and immediately setting the timing mode in host controller. But then before initiating tuning sequence, it also tries to set current limit by sending CMD6 to card which results in data timeout errors in controller if bus speed mode is SDR50/SDR104 mode. So basically bus speed mode should be set only after current limit is set in the card and immediately after setting the bus speed mode, tuning sequence should be initiated.
