| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new device tree enabled pinctrl and gpiolib driver for Samsung SoC's. This driver provides a common and extensible framework for all Samsung SoC's to interface with the pinctrl and gpiolib subsystems. This driver supports only device tree based instantiation and hence can be used only on those Samsung platforms that have device tree enabled. This driver is split into two parts: the pinctrl interface and the gpiolib interface. The pinctrl interface registers pinctrl devices with the pinctrl subsystem and gpiolib interface registers gpio chips with the gpiolib subsystem. The information about the pins, pin groups, pin functions and gpio chips, which are SoC specific, are parsed from device tree node.

This series adds a new driver for ocp2scp (only dt) to which phy drivers are connected. Since currently there is no generic way to create a child device along with doing a pm_runtime_enable (the exact requirement for ocp2scp), I'm creating a separate driver for ocp2scp. Changes from v3: No functional changes. Fixed few comments on filling module details. Changes from v2: Fixed Felipe's comments to avoid using arch_initcall and make dependent drivers return -EPROBE_DEFER case this isn't ready yet. Changes from v1: Fixed Sergei's comments to remove the address in the node name of ocp2scp since the ocp2scp node doesn't have a reg property. Changes from [RFC PATCH v2 0/2] omap: add ocp2scp as a misc driver: Created a new folder drivers/bus and moved ocp2scp driver from misc to drivers/bus.

This driver takes the responsibility of creating all the devices that is connected to OCP2SCP. In the case of OMAP4, USB2PHY is connected to ocp2scp. This also includes device tree support for ocp2scp driver and the documentation with device tree binding information is updated.

The most important is the move to atmel-mci driver in AT91 SoC & boards. The old at91_mci (marked as deprecated) will be removed in 3.7. So all platform data for this old driver are erased and replace by information needed by atmel-mci driver. * tag 'at91-for-next-soc' of git://github.com/at91linux/linux-at91: ARM: at91: add atmel-mci support for chips and boards which can use it ARM: at91/defconfig: change the MCI driver to use in defconfigs ARM: at91: set i2c_board_info.type to "ds1339" directly ARM: at91/defconfig: Remove unaffected config option Signed-off-by: Arnd Bergmann <arnd@arndb.de>

For enabling CPU idle event, CPU arch code should call ledtrig_cpu() stub to trigger idle start or idle end event. These patches convert old style LED driver in arch/arm to gpio_led or new led driver interface. Against 3.5 release and build successfully for all the machines. Test ledtrig-cpu driver on OMAP4 Panda board. v9 --> v10 * fix compiling issue on versatile_defconfig reported by Russell King * rebase to 3.5 kernel and move patches to new git tree v8 --> v9: * use mutex to replace rw_sema pointed out by Tim Gardner * add a new struct led_trigger_cpu * add lock_is_inited to record mutex lock initialization v6 --> v7: * add a patch to unify the led-trigger name * fix some typo pointed * use BUG_ON to detect CPU numbers during building stage v5 --> v6: * replace __get_cpu_var() to per_cpu() * remove smp_processor_id() which is wrong with for_each_possible_cpu() * test on real OMAP4 Panda board * add comments about CPU hotplug in the CPU LED trigger driver v4 --> v5: * rebase all the patches on top of latest linux-next * replace on_each_cpu() with for_each_possible_cpu() * add some description of ledtrig_cpu() API * remove old leds code from driver nwflash.c, which should use a new led trigger then * this trigger driver can be built as module now v3 --> v4: * fix a typo pointed by Jochen Friedrich * fix some building errors * add Reviewed-by and Tested-by into patch log v2 --> v3: * almost rewrote the whole ledtrig-cpu driver, which is more simple * every CPU will have a per-CPU trigger * cpu trigger can be assigned to any leds * fix a lockdep issue in led-trigger common code * other fix according to review v1 --> v2: * remove select operations in Kconfig of every machines * add back supporting of led in core module of mach-integrator * solidate name scheme in ledtrig-cpu.c * add comments of CPU_LED_* cpu led events * fold patches of RealView and Versatile together * add machine_is_ check during assabet led driver init * add some Acked-by in patch logs * remove code for simpad machine in machine-sa11000, since Jochen Friedrich introduced gpiolib and gpio-led driver for simpad * on Assabet and Netwinder machine, LED operations is reversed like: setting bit means turn off leds clearing bit means turn on leds * add a new function to read CM_CTRL register for led driver * 'for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds: ARM: use new LEDS CPU trigger stub to replace old one ARM: mach-sa1100: retire custom LED code ARM: mach-omap1: retire custom LED code ARM: mach-pnx4008: remove including old leds event API header file ARM: plat-samsung: remove including old leds event API header file ARM: mach-pxa: retire custom LED code char: nwflash: remove old led event code ARM: mach-footbridge: retire custom LED code ARM: mach-ebsa110: retire custom LED code ARM: mach-clps711x: retire custom LED code of P720T machine ARM: mach-integrator: retire custom LED code ARM: mach-integrator: move CM_CTRL to header file for accessing by other functions ARM: mach-orion5x: convert custom LED code to gpio_led and LED CPU trigger ARM: mach-shark: retire custom LED code ARM: mach-ks8695: remove leds driver, since nobody use it ARM: mach-realview and mach-versatile: retire custom LED code ARM: at91: convert old leds drivers to gpio_led and led_trigger drivers led-triggers: create a trigger for CPU activity Conflicts: arch/arm/mach-clps711x/p720t.c arch/arm/mach-sa1100/leds-cerf.c arch/arm/mach-sa1100/leds-lart.c Let's hope this is the last time we pull this and it doesn't cause more trouble.
