into cleanup-sparseirq Changes for GPMC (General Purpose Memory Controller) that take it closer for being just a regular device driver. Remove the ancient omap specific atags that are no longer needed. At some point we were planning to pass the bootloader information with custom atags that did not work out too well. There's no need for these any longer as the kernel has been booting fine without them for quite some time. And Now we have device tree support that can be used instead.

2012-08-23ARM: ux500: don't select LEDS_GPIO for snowballArnd Bergmann1-1/+0
Using 'select' in Kconfig is hard, a platform cannot just enable a driver without also making sure that its subsystem is there. Also, there is no actual code dependency between the platform and the gpio leds driver. Without this patch, building without LEDS_CLASS esults in: drivers/built-in.o: In function `create_gpio_led.part.2': governor_userspace.c:(.devinit.text+0x5a58): undefined reference to `led_classdev_register' drivers/built-in.o: In function `gpio_led_remove': governor_userspace.c:(.devexit.text+0x6b8): undefined reference to `led_classdev_unregister' This reverts 8733f53c6 "ARM: ux500: Kconfig: Compile in leds-gpio support for Snowball" that introduced the regression and did not provide a helpful explanation. In order to leave the GPIO LED code still present in normal builds, this also enables the symbol in u8500_defconfig, in addition to the other LED drivers that are already selected there.

2012-08-23ARM: pmu: remove arm_pmu_type enumerationSudeep KarkadaNagesha1-2/+1
The arm_pmu_type enumeration was initially introduced to identify different PMU types in the system, the usual one being that on the CPU (ARM_PMU_DEVICE_CPU). With the removal of the PMU reservation code and the introduction of devicetree bindings for the CPU PMU, the enumeration is no longer required. This patch removes the enumeration and updates the various CPU PMU platform devices so that they no longer pass an .id field referring to identify the PMU type.

2012-07-13ARM: ux500: Remove unused i2c platform_data initialisation codeLee Jones1-35/+4
Now that u5500 is obsolete, u8500 is the only user of the Nomadik i2c driver. As such there is no requirement to differentiate between initialisation values. By the time a new SoC is released, almost all of the ux500 platform will be DT:ed, so we can make decisions based on the compatible property instead.

2012-07-13ARM: ux500: Enable Device Tree support mmci for SnowballLee Jones3-3/+7
Allow proper initialisation for MMC via the mmci driver for the Snowball low-cost development board using DT. At the moment we continue to use DMA setup from platform code. Once the DMA generic DT bindings have been completed we can then port the remainder over to DT.

2012-07-09i2c-nomadik: turn the platform driver to an amba driverAlessandro Rubini1-17/+5
The i2c-nomadik gateware is really a PrimeCell APB device. By hosting the driver under the amba bus we can access it more easily, for example using the generic pci-amba driver. The patch also fixes the mach-ux500 users, so they register an amba device instead than a platform device.

2012-07-09i2c-nomadik: move header to <linux/platform_data/i2c-nomadik.h>Alessandro Rubini2-2/+2
The header and driver are only used by arm/mach-u8500 (and potentially arm/mach-nomadik), but the STA2X11 I/O Hub exports on PCIe a number of devices, including i2c-nomadik. This patch allows compilation of the driver under x86.

2012-07-09ARM: ux500: Register the AB8500 from DB8500 MFDLee Jones3-27/+10
As the AB8500 is a subordinate MFD device to the DB8500-PRCMU, for consistency and a better 1:1 depiction of how the hardware is laid out, it is a good idea to register it in the same way as we do for the other MFD child devices. In order for us to do this successfully we have to pass AB8500's platform data when registering the DB8500-PRCMU from platform code. Also solves this issue: WARNING: at fs/sysfs/dir.c:526 sysfs_add_one+0x88/0xb0() sysfs: cannot create duplicate filename '/bus/platform/devices/ab8500-core.0' Reported-by: Linus Walleij <linus.walleij@linaro.org> Suggested-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-09mfd: Register ab8500 devices using the newly DT:ed MFD APILee Jones1-1/+0
Now the MFD API is Device Tree aware we can use it for platform registration again, even when booting with DT enabled. To aid in Device Node pointer allocation we provide each cell with the associative compatible string.

2012-07-09mfd: Register the ab8500 from db8500-prcmu using the MFD APILee Jones1-2/+0
Hierarchically, the AB8500 is a child of the DB8500 PRCMU. So now that Device Tree is being used and MFD core code is Device Tree aware, we can simply register DB8500 PRCMU from Device Tree in the normal way then allow the DB8500 PRCMU driver to register the AB8500 as a simple MFD device at probe time.

2012-07-06ARM: ux500: Over-ride the DT device naming scheme for pinctrlLee Jones1-0/+2
When pin control mapping tables are written the registered device name is supplied for use in name-based searches within the pinctrl driver. In the case of the DB8500 the string "pinctrl-db8500" is used. However, when we register the driver with Device Tree, its naming convention uses something that looks more like "pinctrl.2". To work around the device naming inconsistencies between devices registered via platform code and the ones registered by Device Tree, we use AUXDATA to over-ride the Device Tree naming scheme.

When MACH_UX500_DT and all related Device Tree configurations are forced off the warning and error below prevent the kernel from compiling. This simple patch fixes both issues and allows for full build and boot of ST-Ericsson's low-cost development board, Snowball.

2012-06-13serial/amba-pl011: move custom pin control to driverLinus Walleij1-53/+1
We had a boot regression in Ux500 in the merge window because two orthogonal pin control schemes for the PL011 were merged at the same time: - One using the .init() and .exit() hooks into the platform for Ux500 putting the pins into default vs sleep state respectively as the port was started/stopped. commit a09806607fd20bed2f8c41fe22793386790a14aa "ARM: ux500: switch to using pinctrl for uart0" - One hogging the default setting at PL011 probe() commit 258e055111d3cde2607e0d04eb91da2f7a59b591 "serial: amba-pl011: adopt pinctrl support" To get a solution that works for both let's scrap the stuff in the platform callbacks, instead have the driver itself select default and sleep states when the port is started/stopped. Hopefully this works for all clients. Platform callbacks are bad for device tree migration anyway, so this rids us of another problem in Ux500.
