Pull irq updates from Thomas Gleixner: "This is a rather large update post rc1 due to the final steps of cleanups and API changes which had to wait for the preparatory patches to hit your tree. - Regression fixes for ARM GIC irqchips - Regression fixes and lockdep anotations for renesas irq chips - The leftovers of the cleanup and preparatory patches which have been ignored by maintainers - Final conversions of the newly merged users of obsolete APIs - Final removal of obsolete APIs - Final removal of ARM artifacts which had been introduced during the conversion of ARM to the generic interrupt code. - Final split of the irq_data into chip specific and common data to reflect the needs of hierarchical irq domains. - Treewide removal of the first argument of interrupt flow handlers, i.e. the irq number, which is not used by the majority of handlers and simple to retrieve from the other argument the irq descriptor. - A few comment updates and build warning fixes" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (40 commits) arm64: Remove ununsed set_irq_flags ARM: Remove ununsed set_irq_flags sh: Kill off set_irq_flags usage irqchip: Kill off set_irq_flags usage gpu/drm: Kill off set_irq_flags usage genirq: Remove irq argument from irq flow handlers genirq: Move field 'msi_desc' from irq_data into irq_common_data genirq: Move field 'affinity' from irq_data into irq_common_data genirq: Move field 'handler_data' from irq_data into irq_common_data genirq: Move field 'node' from irq_data into irq_common_data irqchip/gic-v3: Use IRQD_FORWARDED_TO_VCPU flag irqchip/gic: Use IRQD_FORWARDED_TO_VCPU flag genirq: Provide IRQD_FORWARDED_TO_VCPU status flag genirq: Simplify irq_data_to_desc() genirq: Remove __irq_set_handler_locked() pinctrl/pistachio: Use irq_set_handler_locked gpio: vf610: Use irq_set_handler_locked powerpc/mpc8xx: Use irq_set_handler_locked() powerpc/ipic: Use irq_set_handler_locked() powerpc/cpm2: Use irq_set_handler_locked() ...

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51Z

Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help! Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu

pinctrl: qcom: ssbi: convert null test to IS_ERR test

2015-09-14T07:13:43Z

Since commit 323de9efdf3e ("pinctrl: make pinctrl_register() return proper error code"), pinctrl_register returns an error code rather than NULL on failure. Update some drivers that were introduced more recently. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ expression e,e1,e2; @@ e = pinctrl_register(...) ... when != e = e1 if ( - e == NULL + IS_ERR(e) ) { ... return - e2 + PTR_ERR(e) ; } // Signed-off-by: Julia Lawall Signed-off-by: Linus Walleij

pinctrl/qcom/msm: Prepare msm_gpio_irq_handler for irq argument removal

2015-07-17T19:56:22Z

The irq argument of most interrupt flow handlers is unused or merily used instead of a local variable. The handlers which need the irq argument can retrieve the irq number from the irq descriptor. Search and update was done with coccinelle and the invaluable help of Julia Lawall. Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu Cc: Linus Walleij Cc: linux-gpio@vger.kernel.org

pinctrl: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc

2015-07-17T19:56:20Z

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we already have a pointer to corresponding irq_desc. Signed-off-by: Jiang Liu Cc: Linus Walleij Cc: linux-gpio@vger.kernel.org Signed-off-by: Thomas Gleixner

pinctrl/qcom: Use irq_set_handler_locked()

2015-07-17T19:56:19Z

Use irq_set_handler_locked() as it avoids a redundant lookup of the irq descriptor. Search and replacement was done with coccinelle. Signed-off-by: Thomas Gleixner Cc: Jiang Liu Cc: Julia Lawall Cc: Linus Walleij Cc: linux-gpio@vger.kernel.org

pinctrl: add support for Qualcomm Technologies QDF2xxx ARM64 SoCs

2015-07-17T19:56:14Z

Add the pinctrl driver for the Qualcomm Technologies QDF2xxx ARM64 SoCs, which uses the Qualcomm Technologies TLMM pinctrl/gpio device. This driver is probed via ACPI and uses the pinctrl-msm.c backend driver. This driver is intended to be used only an ACPI-enabled system. As such, UEFI will handle all pin control configuration, so this driver does not provide pin control functions. It is effectively a GPIO-only driver.

pinctrl: qcom: spmi-mpp: Transpose pinmux function

2015-07-17T12:31:19Z

The "function" of the MPP driver was inherited from the GPIO driver, but the differences between the two hardware blocks makes both the driver and the device tree binding to be awkward. Instead of overloading the "normal" function with various modes this patch transposes the pinmux function to represent the three operating modes of the MPP (digital, analog and current sink). The properties of pin pairing and DTEST routing is moved to separate properties. Signed-off-by: Bjorn Andersson Signed-off-by: Linus Walleij

pinctrl: qcom: spmi-mpp: Add support for setting analog output level

2015-07-17T12:29:25Z

When the MPP is configured for analog output the output level is selected by the AOUT_CTL register, this patch makes it possible to control this. Signed-off-by: Bjorn Andersson Signed-off-by: Linus Walleij
