gpu/drm: Kill off set_irq_flags usage

2015-09-16T14:53:38Z

set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

2015-09-04T17:07:45Z

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.3 kernel cycle. There is quite a lot going on in the GPIO subsystem this merge window, so the main matter is decribed below. The hits in other subsystems when making the GPIO flags optional are all ACKed by their respective subsystem maintainers. Core changes: - Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions of the descriptor calls that did not use the flags argument on the end. This was around for too long and eventually Uwe Kleine-König took the time to clean it out and the last users are removed along with the macros in this tag. In several cases the use of flags simplifies the code. For this reason we have (ACKed) patches hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the nail with removing the macros. - Add a fat document describing how much ready-made GPIO stuff we have i the kernel to discourage people from reinventing a square wheel in userspace, as so often happens. - Create a separate lockdep class for each instance of a GPIO IRQ chip instead of using one class for all chips, as the current code will not work with systems with several GPIO chips doing lockdep debugging. - Protect against driver unloading also when a GPIO line is only used as IRQ for the GPIOLIB_IRQCHIP helpers. - If the GPIO chip has no designated owner, assign the parent device driver owner as owner. - Consolidation of chained IRQ handler install/remove replacing all call sites where irq_set_handler_data() and irq_set_chained_handler() were done in succession with a combined call to irq_set_chained_handler_and_data(). This series was created by Thomas Gleixner after the problem was observed by Russell King. - Tglx also made another series of patches switching __irq_set_handler_locked() for irq_set_handler_locked() which is way cleaner. - Tglx and Jiang Liu wrote a good bunch of patches to make use of irq_desc_get_xxx() accessors and avoid looking up irq_descs from IRQ numbers. The goal is to get rid of the irq number from the handlers in the IRQ flow which is nice. - Rob Herring killed off the set_irq_flags() for all GPIO drivers. This was an ARM specific function that is replaced with the generic irq_modify_status() where special flags are actually needed. - When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER if the pin controller isn't available. Pretty logical, yet needed to be fixed. - If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call back, then call these instead of the defaults provided by the GPIOLIB. - Fix an undocumented ABI hole: named GPIOs were not properly documented. Driver improvements: - Add get_direction() support to the generic GPIO driver, it's strange that we didn't have that before. - Make it possible to have input-only GPIO chips using the generic GPIO driver. - Clean out platform data support from the Emma Mobile (EM) driver - Finegrained runtime PM support for the RCAR driver. - Support r8a7795 (R-car H3) in the RCAR driver. - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver. - Some consolidation and new support in the MPC8xxx driver, we now support MPC5125. - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw spinlocks making it work better with the realime patches. - Interrupt support for the EXTRAXFS GPIO driver. - Make the ETRAXFS GPIO driver support also ARTPEC-3. - Interrupt and wakeup support for the BRCMSTB driver, also for wakeup from S5 cold boot. - Mask MXC IRQs during suspend. - Improve OMAP2 GPIO set_debounce() to work according to spec. - The VF610 driver handles IRQs properly. New drivers: - ZTE ZX GPIO driver" * tag 'gpio-v4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (87 commits) Revert "gpio: extraxfs: fix returnvar.cocci warnings" gpio: tc3589x: use static container helper gpio: xlp: fix error return code gpio: vf610: handle level IRQ's properly gpio: max732x: Fix error handling in probe() gpio: omap: fix clk_prepare/unprepare usage gpio: omap: protect regs access in omap_gpio_irq_handler gpio: omap: fix omap2_set_gpio_debounce gpio: omap: switch to use platform_get_irq gpio: omap: remove wrong irq_domain_remove usage in probe gpiolib: add description for gpio irqchip fields in struct gpio_chip gpio: extraxfs: fix returnvar.cocci warnings gpiolib: irqchip: use different lockdep class for each gpio irqchip gpio/grgpio: fix deadlock in grgpio_irq_unmap() Documentation: gpio: consumer: describe active low property gpio: mxc: fix section mismatch warning gpio/mxc: mask gpio interrupts in suspend gpio: omap: Fix missing raw locks conversion gpio: brcmstb: support wakeup from S5 cold boot gpio: brcmstb: Add interrupt and wakeup source support ...
