* Drivers: pinctrl: remove __dev* attributes.Greg Kroah-Hartman2013-01-048-20/+17Star
| | | | | | | | | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

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.

* | pinctrl: SPEAr: Add SoC specific gpio configuration routinesShiraz Hashim2012-11-113-14/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Different SPEAr SoCs have different approach to configure pins as gpios. Some configure a group of gpios with single register bit and others have one bit per gpio pin. Only earlier one is implemented till now, this patch adds support for later one. Here we add callbacks to SoC specific code to configure gpios in gpio_request_enable(). That will do additional SoC specific configuration to enable gpio pins. We also implement this callback for SPEAr1340 in this patch.

| | | | | | | | | | | | | | SPEAr1310 has separate PCI and PCIe implementations which are not muxed with each other. Presently they have been implemented as muxed together with SATA and are represented wrongly in the software. In reality only PCIe and SATA implementations are muxed with each other. This patch separates out pci pins creating a new pingroup and function for pci.
