2014-09-24usb: phy: twl4030-usb: Use mutex instead of spinlock for protecting the dataTony Lindgren
We're using threaded irq on a I2C bus and we're sleeping in twl4030_usb_irq() as it calls twl4030_usb_linkstat() which calls the i2c functions. If we ever need to lock for longer I2C transaction sequences a mutex will allow us to do that easily.

2014-09-24usb: phy: twl4030-usb: Move code from twl4030_phy_power to the runtime PM callsTony Lindgren
We don't need twl4030_phy_power() any longer now that we have the runtime PM calls. Let's get rid of it as it's confusing. No functional changes, just move the code and use res instead of ret as we are not returning that value.

2014-09-24phy: phy-spear1340-miphy: Remove unncessary site specific OOM messagesPeter Griffin
The site specific OOM messages are unncessary, because they duplicate messages from the memory subsystem which include dump_stack(). Removing these superflous messages makes the kernel smaller. A discussion here http://patchwork.ozlabs.org/patch/324158/ found that all error paths from kzalloc will print a error message, and that any error path which maybe found which doesn't would be considered a bug in kzalloc.

2014-09-24phy: Renesas R-Car Gen2 PHY driverSergei Shtylyov
This PHY, though formally being a part of Renesas USBHS controller, contains the UGCTRL2 register that controls multiplexing of the USB ports (Renesas calls them channels) to the different USB controllers: channel 0 can be connected to either PCI EHCI/OHCI or USBHS controllers, channel 2 can be connected to PCI EHCI/OHCI or xHCI controllers. This is a new driver for this USB PHY currently already supported under drivers/ usb/phy/. The reason for writing the new driver was the requirement that the multiplexing of USB channels to the controller be dynamic, depending on what USB drivers are loaded, rather than static as provided by the old driver. The infrastructure provided by drivers/phy/phy-core.c seems to fit that purpose ideally. The new driver only supports device tree probing for now.

2014-09-24spi: pl022: Add support for chip select extensionAnders Berg
Add support for a extended PL022 which has an extra register for controlling up to five chip select signals. This controller is found on the AXM5516 SoC. Unfortunately the PrimeCell identification registers are identical to a standard ARM PL022. To work around this, the peripheral ID must be overridden in the device tree using the "arm,primecell-periphid" property with the value 0x000b6022.

2014-09-24spi: Fix possible ZERO_SIZE_PTR pointer dereferencing error.Xiubo Li
Since we cannot make sure the 'n' will always be none zero here, and then if either equal to zero, the kzalloc() will return ZERO_SIZE_PTR, which equals to ((void *)16). So this patch fix this with just doing the zero check before calling kzalloc(). Signed-off-by: Xiubo Li <Li.Xiubo@freescale.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-09-24gpio: Fix potential NULL handler data in chained irqchip handlerJarkko Nikula
There is possibility with misconfigured pins that interrupt occurs instantly after setting irq_set_chained_handler() in gpiochip_set_chained_irqchip(). Now if handler gets called before irq_set_handler_data() the handler gets NULL handler data. Fix this by moving irq_set_handler_data() call before irq_set_chained_handler() in gpiochip_set_chained_irqchip().
