* ARM: debug: move 8250 debug include into arch/arm/include/debug/Russell King2013-08-251-18/+0
| | | | | | | | | Now that the 8250 debug include can stand alone without requiring platforms to provide any macros, move it into the debug directory so it can be directly included. This allows us to get rid of a lot of debug-macros include files. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* dmaengine: PL08x: Avoid collisions with get_signal() macroMark Brown2013-07-051-2/+2
| | | | | | | | | | | | | As pointed out by Arnd Bergmann there is a get_signal macro definied in linux/signal.h which can conflict with the platform data callback function of the same name leading to confusing errors from the compiler (especially if signal.h manages to get pulled into the driver itself due to header dependencies). Avoid such errors by renaming get_signal and put_signal in the platform data to get_xfer_signal and put_xfer_signal.

* | ARM: delete struct sys_timerStephen Warren2012-12-243-8/+3
|/ | | | | | | | | | | | | | | | | | Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

* ARM: LPC32xx: Cleanup irq.cRoland Stigge2012-11-071-5/+0
| | | | | | | | | | | This patch removes the IRQ mask initialization which is already done some lines above. This was actually a bug: The init was supposed to set the bits for the (chained) SUB IRQs. But this is already fixed by the previous patch, doing this implicitely via irq_set_chained_handler(). Signed-off-by: Roland Stigge <stigge@antcom.de>

| | | | | | | | | | | | | | | | | | | This patch fixes the issue of an access to a yet uninitialized data structure at the point where irq_set_chained_handler() was called by moving the respective calls to the end of lpc32xx_init_irq(). The call path was: irq_set_chained_handler() -> __irq_set_handler() -> irq_startup() -> irq_enable() -> desc->irq_data.chip->irq_unmask() at which point lpc32xx_unmask_irq() effectively read desc->irq_data.hwirq which was only later initialized.

It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while. Sorry for the overhead."

It's still early days on mainline support, with just the basics working. But it has to start somewhere! Beyond that there's some conversions of clock infrastructure on tegra to common clock, misc updates for several other platforms, and OMAP now has its own bus (under drivers/bus) to manage its devices through. This branch adds two new directories outside of arch/arm: drivers/irqchip for new irq controllers, and drivers/bus for the above OMAP bus. It's expected that some of the other platforms will migrate parts of their platforms to those directories over time as well."

* ARM: LPC32xx: DT conversion of Standard UARTsRoland Stigge2012-06-142-116/+1
| | | | | | | | | | | | This patch switches from static serial driver initialization to devicetree configuration. This way, the Standard UARTs of the LPC32xx SoC can be enabled individually via DT. E.g., instead of Kconfig configuration, the phy3250.dts activates UARTs 3 and 5. Signed-off-by: Roland Stigge <stigge@antcom.de> Tested-by: Alexandre Pereira da Silva <aletes.xgr@gmail.com>
* ARM: LPC32xx: Add MMC controller supportRoland Stigge2012-06-141-4/+39
| | | | | | | | | This patch adds support for the MMC controller of the LPC32xx SoC to the platform initialization via the pl08x primecell driver. Lacking more complete DT support, done via DT auxdata. Signed-off-by: Roland Stigge <stigge@antcom.de> Acked-by: Alexandre Pereira da Silva <aletes.xgr@gmail.com>
* ARM: LPC32xx: Clock adjustment for key matrix controllerRoland Stigge2012-06-141-1/+1
| | | | | | | | The clock.c file needs to be changed to match the automatic device name to its clock. Signed-off-by: Roland Stigge <stigge@antcom.de> Acked-by: Rob Herring <rob.herring@calxeda.com>
* ARM: LPC32xx: Add DMA configuration to platform dataRoland Stigge2012-06-141-0/+31
| | | | | | | This patch adds DMA channel configuration to the LPC32xx platform file. The configured DMA signalling is generic for LPC32xx SoC and is not board specific. Signed-off-by: Roland Stigge <stigge@antcom.de>
* ARM: LPC32xx: Remove SLC controller initialization from platform initRoland Stigge2012-06-141-4/+0
| | | | | | | | | Since we now support two MTD NAND controllers (MLC and SLC) for LPC32xx via DT, we don't initialize the SLC controller statically anymore, but do it via the clock setup (see previous patch).

* ARM: LPC32xx: Clock initialization for NAND controllersRoland Stigge2012-06-141-2/+14
| | | | | | | This patch adds clock initialization for the MLC NAND controller of the LPC32xx SoC and adjusts it for the SLC controller. Signed-off-by: Roland Stigge <stigge@antcom.de>

Changes do touch architecture code to remove the need for separate arm/gpio.h includes in most architectures. Some new drivers are added, and a number of gpio drivers are converted to use irq_domains for gpio inputs used as interrupts. Device tree support has been amended to allow multiple gpio_chips to use the same device tree node. Remaining changes are primarily bug fixes." * tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6: (33 commits) gpio/generic: initialize basic_mmio_gpio shadow variables properly gpiolib: Remove 'const' from data argument of gpiochip_find() gpio/rc5t583: add gpio driver for RICOH PMIC RC5T583 gpiolib: quiet gpiochip_add boot message noise gpio: mpc8xxx: Prevent NULL pointer deref in demux handler gpio/lpc32xx: Add device tree support gpio: Adjust of_xlate API to support multiple GPIO chips gpiolib: Implement devm_gpio_request_one() gpio-mcp23s08: dbg_show: fix pullup configuration display Add support for TCA6424A gpio/omap: (re)fix wakeups on level-triggered GPIOs gpio/omap: fix broken context restore for non-OFF mode transitions gpio/omap: fix missing check in *_runtime_suspend() gpio/omap: remove cpu_is_omapxxxx() checks from *_runtime_resume() gpio/omap: remove suspend/resume callbacks gpio/omap: remove retrigger variable in gpio_irq_handler gpio/omap: remove saved_wakeup field from struct gpio_bank gpio/omap: remove suspend_wakeup field from struct gpio_bank gpio/omap: remove saved_fallingdetect, saved_risingdetect gpio/omap: remove virtual_irq_start variable ...

| * gpio/lpc32xx: Add device tree supportRoland Stigge2012-05-181-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds device tree support for gpio-lpc32xx.c. To register the various GPIO banks as (struct) gpio_chips via the same DT gpio-controller, we utilize the adjusted of_xlate API to manipulate the actually used struct gpio_chip.
