2013-10-30mmc: jz4740: Move away from using deprecated APIsUlf Hansson
Suspend and resume of cards are being handled from the protocol layer and consequently the mmc_suspend|resume_host APIs are deprecated. This means we can simplify the suspend|resume callbacks by removing the use of the deprecated APIs.

2013-08-24mmc: slot-gpio: Add debouncing capability to mmc_gpio_request_cd()Laurent Pinchart
Add a debounce parameter to the mmc_gpio_request_cd() function that enables GPIO debouncing when set to a non-zero value. This can be used by MMC host drivers to enable debouncing on the card detect signal.

2013-08-24mmc: jz4740: fix return value check in jz4740_mmc_probe()Wei Yongjun
In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Also there is already a error message within devm_ioremap_resource(), so remove the dev_err call to avoid redundant error message.

2013-06-27mmc: jz4740: Use managed resourcesLars-Peter Clausen
Use managed resources for the mmio memory region and the clock. Makes the code a bit shorter. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Chris Ball <cjb@laptop.org>
2013-06-27mmc: jz4740: Use slot-gpio helpersLars-Peter Clausen
Use the slot-gpio helpers to handle the write protect and card detect GPIO pins instead of re-implementing the same functionality in the driver. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Chris Ball <cjb@laptop.org>
2013-06-27mmc: jz4740: Use SIMPLE_DEV_PM_OPSLars-Peter Clausen
It's a bit shorter than open-conding it. While we are at it also make jz4740_mmc_pm_ops static. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Chris Ball <cjb@laptop.org>

2013-05-26mmc: remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.
