2016-07-29mmc: sdhci-pltfm: Drop define for SDHCI_PLTFM_PMOPSUlf Hansson1-1/+1
Due to previous changes this define has no longer a purpose. Instead move the sdhci-pltfm drivers over to use the exported struct sdhci_pltfm_pmops. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2015-03-23mmc: sdhci: set the .remove to sdhci_pltfm_unregister()Kevin Hao1-6/+1
In these drivers, the driver specific .remove function just a simple wrapper of function sdhci_pltfm_unregister(). So remove these wrappers and just set .remove to sdhci_pltfm_unregister(). Signed-off-by: Kevin Hao <haokexin@gmail.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2015-03-23mmc: sdhci: disable the clock in sdhci_pltfm_unregister()Kevin Hao1-7/+1
So we can avoid to sprinkle the clk_disable_unprepare() in many drivers. Signed-off-by: Kevin Hao <haokexin@gmail.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2015-03-23mmc: sdhci-dove: kill the driver specific private structKevin Hao1-21/+5
There is only one "clk" member in this driver specific private struct. Actually we can use the "clk" member in the struct sdhci_pltfm_host, and then kill this struct completely. Signed-off-by: Kevin Hao <haokexin@gmail.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2015-03-23mmc: sdhci-dove: remove the unneeded error checkKevin Hao1-4/+2
The function clk_disable_unprepare() already take care of either error or null cases. Signed-off-by: Kevin Hao <haokexin@gmail.com> 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>
2014-05-23mmc: sdhci-dove: use mmc_of_parse() and remove card_tasklet CD handlerSebastian Hesselbarth1-69/+5
f8ec589b86f6 ("mmc: sdhci-dove: allow GPIOs to be used for card detection on Dove" added a gpio based card detect interrupt handler that was hooked up into card_tasket. 3560db8e247a ("mmc: sdhci: push card_tasklet into threaded irq handler") now removed that very card_tasklet causing sdhci-dove to fail on build with: drivers/mmc/host/sdhci-dove.c: In function 'sdhci_dove_carddetect_irq': drivers/mmc/host/sdhci-dove.c:42:24: error: 'struct sdhci_host' has no member named 'card_tasklet' To fix both the build error and get a working gpio card detection without card_tasklet, replace sdhci_get_of_property() with more recent mmc_of_parse(). It takes care of gpio-based card detect passed through DT already and allows to remove the offending code sections dealing with removed card_tasklet.

Add a param to allow users of sdhci_pltfm to allocate private space in calls to sdhci_pltfm_init+sdhci_pltfm_register. This is implemented in the same way as sdhci does for its users.

Basically all drivers can have sdhci_ops struct const, but almost none do. This patch constifies all sdhci_ops struct declarations where possible.

The sdhci_pltfm_data struct is never modified within the sdhci_pltfm module. So make the pdata parameter to sdhci_pltfm_init and sdhci_pltfm_register const. This allows drivers to declare their sdhci_pltfm_data struct as const. This patch also makes the sdhci_pltfm_data declarations const where possible.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core 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.

2012-12-06mmc: sdhci-dove: allow GPIOs to be used for card detection on DoveRussell King1-6/+67
This commit taken from Rabeeh's Cubox kernel and re-worked for DT; Sebastian Hasselbrath is believed to be the original author. Some Cuboxes require a GPIO for card detection; this implements the optional GPIO support for card detection. This GPIO is logic 0 for card inserted.

2011-07-21mmc: sdhci: change sdhci-pltfm into a moduleShawn Guo1-1/+0
There are a couple of problems left from the sdhci pltfm and OF consolidation changes. * When building more than one sdhci-pltfm based drivers in the same image, linker will give multiple definition error on the sdhci-pltfm helper functions. For example right now, building sdhci-of-esdhc and sdhci-of-hlwd together is a valid combination from Kconfig view. * With the current build method, there is error with building the drivers as module, but module installation fails with modprobe. The patch fixes above problems by changing sdhci-pltfm into a module. To avoid EXPORT_SYMBOL on so many big endian IO accessors, it moves these accessors into sdhci-pltfm.h as the 'static inline' functions. As a result, sdhci.h needs to be included in sdhci-pltfm.h, and in turn can be removed from individual drivers which already include sdhci-pltfm.h.
