git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device-tree updates from Olof Johansson: "Part 1 of device-tree updates for 3.10. The bulk of the churn in this branch is due to i.MX moving from C-defined pin control over to device tree, which is a one-time conversion that will allow greater flexibility down the road. Besides that, there's PCI-e bindings for Marvell mvebu platforms and a handful of cleanups to tegra due to the new include file functionality of the device tree compiler" * tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (113 commits) arm: mvebu: PCIe Device Tree informations for Armada XP GP arm: mvebu: PCIe Device Tree informations for Armada 370 DB arm: mvebu: PCIe Device Tree informations for Armada 370 Mirabox arm: mvebu: PCIe Device Tree informations for Armada XP DB arm: mvebu: PCIe Device Tree informations for OpenBlocks AX3-4 arm: mvebu: add PCIe Device Tree informations for Armada XP arm: mvebu: add PCIe Device Tree informations for Armada 370 ARM: sunxi: unify osc24M_fixed and osc24M arm: vt8500: Add SDHC support to WM8505 DT ARM: dts: Add a 64 bits version of the skeleton device tree ARM: mvebu: Add Device Bus and CFI flash memory support to defconfig ARM: mvebu: Add support for NOR flash device on Openblocks AX3 board ARM: mvebu: Add support for NOR flash device on Armada XP-GP board ARM: mvebu: Add Device Bus support for Armada 370/XP SoC ARM: dts: imx6dl-wandboard: Add USB Host support ARM: dts: imx51 cpu node ARM: dts: Add missing imx27-phytec-phycore dtb target ARM: dts: Add NFC support for i.MX27 Phytec PCM038 module ARM: i.MX51: Add PATA support ARM: dts: Add initial support for Wandboard Dual-Lite ...
2013-04-09pinctrl: imx: move hard-coding data into device treeShawn Guo1-79/+47
Currently, all imx pinctrl drivers maintain a big array of struct imx_pin_reg which hard-codes data like register offset and mux mode setting for each pin function. Every time a new imx SoC support is added, we need to add such a big mount of data. With moving to single kernel build, it's only matter of time to be blamed on memory consuming. With DTC pre-processor support in place, the patch moves all these data into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and changing the PIN_FUNC_ID parsing code a little bit. The pin id gets re-numbered based on mux register offset, or config register offset if the pin has no mux register, so that kernel can identify the pin id from register offsets provided by device tree. As a bonus point of the change, those arbitrary magic numbers standing for particular PIN_FUNC_ID in device tree sources are now replaced by macros to improve the readability of dts files.

2013-01-22pinctrl: Convert to devm_ioremap_resource()Thierry Reding1-3/+3
Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.

2013-01-04Drivers: pinctrl: remove __dev* attributes.Greg Kroah-Hartman1-9/+10
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.

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.

2012-07-03pinctrl: pinctrl-imx: fix map setting problem if NO_PAD_CTL is setHui Wang1-6/+7
new_map is allocated according to map_num instead of grp->npins, if a pin or some pins of a group has NO_PAD_CTL property, the map_num and the grp->npin are different definitely. When we set mapping information to the new_map[], we should skip those pins with NO_PAD_CTL from index, otherwise it is possible the driver will aceesss to a unallocated region.

2012-06-12pinctrl: pinctrl-imx: free allocated pinctrl_map structure only once and use ↵Devendra Naga1-16/+12
kernel facilities for IMX_PMX_DUMP a) as we allocate the pinctrl_map structure at imx_dt_node_to_map at line 167, anyway if its an element, or a num_elements * (sizeof(type)) elements allocated to one single pointer must be freed only once. CASE. A) as new_map is not moved and allocated like, for (i = 0; i < MAX_ELEMS; i++) { new_map[i] = kmalloc(numelems * size, GFP_KERNEL); } its freed as for (i = 0; i < MAX_ELEMS; i++) { kfree(new_map[i]); } CASE. B) and its allocated like new_map = kmalloc(numelems * size, GFP_KERNEL); it just needs kfree not as case A's. b) use KERN_DEBUG facility for the IMX_PMX_DUMP macro.

2012-05-02pinctrl: pinctrl-imx: add imx pinctrl core driverDong Aisheng1-0/+627
The driver has mux and config support while the gpio is still not supported. For select input setting, the driver will handle it internally and do not need user to take care of it. The pinctrl-imx core driver will parse the dts file and dynamically create the pinmux functions and groups. Each IMX SoC pinctrl driver should register pins with a pin register map including mux register and config register and select input map to core for proper operations.
