2012-07-13ARM: ux500: Move rtc-pl031 registration to Device Tree when enabledLee Jones
During a Device Tree boot, all probing will now be completed on parse of the Device Tree binary. In the same patch we remove platform registration of the Real Time Clock. Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2012-07-13ARM: ux500: Enable the AB8500 RTC for all DT:ed DB8500 based devicesLee Jones
Here we add a node for the AB8500 Real Time Clock in all devices supporting the DB8500. The AB8500 RTC driver makes use of named interrupts we provide support for this too. Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2012-07-13ARM: ux500: Correctly reference IRQs supplied by the AB8500 from Device TreeLee Jones
The AB8500 driver has now been provided with IRQ domain support. This means we can request IRQs from any of it's uses via Device Tree. This patch advertises the AB8500 as an Interrupt Controller and provides the correct calls in the format the driver expects.

2012-07-13ARM: ux500: Apply ab8500-debug node do the db8500 DT structureLee Jones
This node has no properties. It merely allows probing of the ab8500-debugfs driver during Device Tree initialisation. Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2012-07-13ARM: ux500: Add a ab8500-usb Device Tree node for db8500 based devicesLee Jones

2012-07-13ARM: ux500: Enable the user LED on Snowball via Device TreeLee Jones
This patch enables and illuminates the user_led on the Snowball low-cost development board using DT. It also removes initialisation carried out from platform code. Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2012-07-13ARM: ux500: Kconfig: Compile in leds-gpio support for SnowballLee Jones
Code exists in the mop500 board file (used for HREF and Snowball) to initialise Snowball's user LED via the leds-gpio driver. However, the driver isn't currently built when using the current configuration. This patch aims to change that behavior.

2012-07-13ARM: ux500: Provide auxdata to be used as name base clock search for nmk-i2cLee Jones
This patch provides a way for find_clk() to complete its name-based searches and still find the nmk-i2c clocks. As Device Tree has a different naming structure to that of more traditional initialisation methods, find_clk() not succeed without these bindings.

2012-07-13ARM: ux500: Remove unused i2c platform_data initialisation codeLee Jones
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 Jones
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.

2012-07-13ALSA: snd-usb: move calls to usb_set_interfaceDaniel Mack
The rework of the snd-usb endpoint logic moved the calls to snd_usb_set_interface() into the snd_usb_endpoint implemenation. This changed the order in which these calls are issued to the device, and thereby caused regressions for some webcams. Fix this by moving the calls back to pcm.c for now to make it work again and use snd_usb_endpoint_activate() to really tear down all remaining URBs in the flight, consequently fixing another regression caused by USB packets on the wire after altsetting 0 has been selected.

2012-07-13Input: spear_keyboard - reconfigure operating frequency on suspendShiraz Hashim
On some platform it may happen that the input clock to keyboard may change during suspend, thus impacting its wakeup capability. There is no means for keyboard driver to know this frequency before hand. Hence introduce a platform data 'suspended_rate' which indicates the frequency during suspend at which keyboard operates. Accordingly reprogram keyboard while going into suspend and restore original configuration at the time of resume.

2012-07-13Input: spear_keyboard - fix clock handling during suspend/resumeShiraz Hashim
SPEAr keyboard should normally disable clock during suspend and enable it during resume.

The set_level callback in the controller data, which is used to configure the slave select line, cannot be supported when migrating the driver to device tree based discovery. Since all the platforms currently use gpio as the slave select line, this callback can be removed from the controller data and replaced with call to gpio_set_value in the driver.
