git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq fixes from Thomas Gleixner: "This contains: - a series of fixes for interrupt drivers to prevent a potential race when installing a chained interrupt handler - a fix for cpumask pointer misuse - a fix for using the wrong interrupt number from struct irq_data - removal of unused code and outdated comments - a few new helper functions which allow us to cleanup the interrupt handling code further in 4.3 I decided against doing the cleanup at the end of this merge window and rather do the preparatory steps for 4.3, so we can run the final ABI change at the end of the 4.3 merge window with less risk" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (26 commits) ARM/LPC32xx: Use irq not hwirq for __irq_set_handler_locked() genirq: Implement irq_set_handler_locked()/irq_set_chip_handler_name_locked() genirq: Introduce helper irq_desc_get_irq() genirq: Remove irq_node() genirq: Clean up outdated comments related to include/linux/irqdesc.h mn10300: Fix incorrect use of irq_data->affinity MIPS/ralink: Fix race in installing chained IRQ handler MIPS/pci: Fix race in installing chained IRQ handler MIPS/ath25: Fix race in installing chained IRQ handler MIPS/ath25: Fix race in installing chained IRQ handler m68k/psc: Fix race in installing chained IRQ handler avr32/at32ap: Fix race in installing chained IRQ handler sh/intc: Fix race in installing chained IRQ handler sh/intc: Fix potential race in installing chained IRQ handler pinctrl/sun4i: Fix race in installing chained IRQ handler pinctrl/samsung: Fix race in installing chained IRQ handler pinctrl/samsung: Fix race in installing chained IRQ handler pinctrl/exynos: Fix race in installing chained IRQ handler pinctrl/st: Fix race in installing chained IRQ handler pinctrl/adi2: Fix race in installing chained IRQ handler ...

2015-06-17pinctrl: rockchip: add support for the rk3368Heiko Stübner1-0/+91
The rk3368 is the first ARM64 soc from Rockchip, but seems to share most peripherals with the ARM32 soc, including the pinctrl functionality. The only notable difference is - as with every Rockchip soc - that the offsets in the General Register Files moved around and a split of the pmu section of the rk3288 into pmu and pmugrf (pmu general register files) sections. The pinctrl driver of course only needs the pmugrf registers for controlling the pin settings. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Changes in version 5: - resolved rejects, refreshed the patch; - added Laurent Pinchart's ACK. Changes in version 4: - reused the PORT_GP_26() macro to #define PORT_GP_28(). Changes in version 3: - removed the platform device ID; - added PORT_GP_26() and PORT_GP_28() macros, used them for GPIO1/5/6 in the CPU_ALL_PORT() macro. Changes in version 2: - rebased the patch.

2015-06-10pinctrl: make pinctrl_register() return proper error codeMasahiro Yamada45-95/+98
Currently, pinctrl_register() just returns NULL on error, so the callers can not know the exact reason of the failure. Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some -ENOMEM on error of pinctrl_register(), although the error code might be different from the real cause of the error. This commit reworks pinctrl_register() to return the appropriate error code and modifies all of the pinctrl drivers to use IS_ERR() for the error checking and PTR_ERR() for getting the error code.

In order to be consistent with other SoCs having two SPI busses, this commit renames the functions of the first SPI bus to 'spi0' instead of just 'spi'.

2015-06-10pinctrl: mvebu: armada-370: align VDD cpu-pd pin naming with datasheetThomas Petazzoni1-1/+1
For consistency with the datasheet, this commit renames the VDD function of the MPP4 pin. While this changes the DT compatibility, it is not considered to be a problem since this pin is unlikely to be used for anything but debugging purposes.

2015-06-10pinctrl: mvebu: armada-{370,xp}: normalize ethernet txclkout pinsThomas Petazzoni2-3/+3
This commit normalizes the naming of the Ethernet txclkout pin to be the same accross Marvell SoCs. It is worth mentioning that the DT binding documentation of the Armada XP was wrong for MPP12: it said the function was ge1(txd0), while it is in fact ge1(txclkout). It is however not really a fix worth sending to stable since it does not change the behavior, and the driver itself was correct. Since only the subnames are changed, DT backward compatibility is not affected.

2015-06-10pinctrl: mvebu: armada-{370,375,38x,39x,xp}: normalize TDM pinsThomas Petazzoni5-13/+13
This commit normalizes the naming of the TDM pins accross the different Marvell SoCs. Mainly it consists in: * Removing the 'n' from signal names: 'intn' becomes 'int' and 'rstn' becomes 'rst' * Renaming the main name 'tdm2c' to 'tdm' on Armada 38x. * Change the main name 'tdm-1' to 'tdm' for one of the pins of the Armada XP The last two changes affect DT compatibility, but since the TDM interface is nowhere near being supported in mainline, it should not be considered to be a serious problem at this point.

2015-06-10pinctrl: mvebu: armada-39x: align NAND pin namingThomas Petazzoni1-2/+2
All SoCs use "nand" to designate NAND pins, only Armada 39x is using "nd", which is not consistent. This commit fixes that by renaming the corresponding functions. It also changes the subnames from rbn0/rbn1 to rb0/rb1, to respect the convention used everywhere that we don't encode the 'n' part of signal names. While this commit changes the main name of function, therefore potentially breaking the DT compatibility, this is not a problem since Armada 39x is a brand new SoC which isn't used in production yet.

2015-06-10pinctrl: mvebu: armada-{370,375,38x,39x}: normalize dev pinsThomas Petazzoni4-15/+15
This commit modifies the definition of the Device Bus interface pins to be consistent accross SoCs. Especially, it removes the 'n' indicators that we don't encode in the subnames of pins: 'dev(wen0)' becomes 'dev(we0)' 'dev(wen1)' becomes 'dev(we1)' 'dev(oen)' becomes 'dev(oe)' etc. In addition, it fixes the Armada 375 DT binding documentation, which forgot to document the 'dev' function for MPP46, MPP57 and MPP63. Since only the subnames are changed, this commit does not affect DT compatibility.

In order to be consistent with the datasheet and some other SoCs, this commit renames the SDIO pins of the Armada 39x from "sd" to "sd0". While this changes the DT binding, this is not a problem since Armada 39x is a brand new SoC which isn't used in production yet (so now is the right time to fix such things).

This commit makes the dram functions naming (both the name and subname) consistent accross SoC, by using: dram(vttctrl) dram(deccerr) in all Marvell SoCs. Due to the change to the name, it changes the DT binding, but these functions are not used by any in-tree Device Tree file, and are very unlikely to be used by anyone.

A new revision of the Marvell Armada 38x hardware datasheet unveiled that the definition of some of the PCIe functions were not correct. This commit fixes the pinctrl driver accordingly. Some PCIe functions simply do not exist, some of the PCIe functions in fact were corresponding to other functions, and some PCIe functions have been added.
