2017-12-15mmc: sdhci-spear: Handle return value of platform_get_irqArvind Yadav1-0/+4
platform_get_irq() can fail here and we must check its return value. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2017-04-24mmc: sdhci: Let drivers decide whether to use mmc_retune_needed() with pmAdrian Hunter1-0/+3
Devices might save and restore tuning values so that re-tuning might not be needed after a pm transition. Let drivers decide by pushing the mmc_retune_needed() logic down to them.

2015-03-23mmc: sdhci-spear: Remove exported headerUlf Hansson1-26/+9
Move the member for card_int_gpio into the struct spear_sdhci. In this way we eliminate the last user of the struct sdhci_plat_data, which enables us to remove the exported header for sdhci-spear. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2015-03-23mmc: sdhci-spear: Simplify by adding build dependency to CONFIG_OFUlf Hansson1-16/+4
This driver is used on SoCs which are using CONFIG_OF. By adding a compile dependency in the Kconfig, it enables us to simplify some code. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2014-09-09mmc: remove .owner field for drivers using module_platform_driverPeter Griffin1-1/+0
This patch removes the superflous .owner field for drivers which use the module_platform_driver API, as this is overriden in platform_driver_register anyway. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2014-05-22mmc: sdhci: convert sdhci_set_uhs_signaling() into a library functionRussell King1-0/+1
Add sdhci_set_uhs_signaling() and always call the set_uhs_signaling method. This avoids quirks being added into sdhci_set_uhs_signaling().

2014-05-22mmc: sdhci: convert reset into a library functionRussell King1-0/+1
Rather than having platform_reset_enter/platform_reset_exit methods, turn the core of the reset handling into a library function which platforms can call at the appropriate moment in their (new) reset method.

2014-03-04mmc: sdhci-spear: use generic card detection gpio supportRussell King1-62/+17
sdhci has support for using GPIOs for card detection. If we have a GPIO specified, we can use that directly, without needing our own interrupt handler. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Chris Ball <chris@printf.net>
2014-03-04mmc: sdhci-spear: remove support for power gpioRussell King1-32/+0
None of this code is currently used: there are no definitions of struct sdhci_plat_data in arch/arm, neither are there any DT properties which use card_power_gpio/power_active_high/power_always_enb. In any case, slot power control should be rigged up via vmmc and the regulator subsystem in the DT case.

2014-03-04mmc: sdhci-spear: simplify resource handlingRussell King1-27/+13

2014-03-04mmc: sdhci-spear: fix platform_data usageRussell King1-26/+17
sdhci-spear is unsafe should a probe fail or defer, since it overwrites the platform_data with its own driver-private data. It's trivial to fix as SDHCI allows for driver-private data to be appended to its own structure - we just need to arrange the code to allow this.

2013-05-26mmc: remove unnecessary platform_set_drvdata()Jingoo Han1-2/+0
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.

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following build warning when CONFIG_PM_SLEEP is not selected.

2012-12-11Merge tag 'driver-core-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-coreLinus Torvalds1-7/+5
Pull driver core updates from Greg Kroah-Hartman: "Here's the large driver core updates for 3.8-rc1. The biggest thing here is the various __dev* marking removals. This is going to be a pain for the merge with different subsystem trees, I know, but all of the patches included here have been ACKed by their various subsystem maintainers, as they wanted them to go through here. If this is too much of a pain, I can pull all of them out of this tree and just send you one with the other fixes/updates and then, after 3.8-rc1 is out, do the rest of the removals to ensure we catch them all, it's up to you. The merges should all be trivial, and Stephen has been doing them all in linux-next for a few weeks now quite easily. Other than the __dev* marking removals, there's nothing major here, some firmware loading updates and other minor things in the driver core. All of these have (much to Stephen's annoyance), been in linux-next for a while.
