* genirq/irqdomain: Rename early argument of irq_domain_activate_irq()Thomas Gleixner2017-12-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'early' argument of irq_domain_activate_irq() is actually used to denote reservation mode. To avoid confusion, rename it before abuse happens. No functional change.

* kernel/irq: Extend lockdep class for request mutexAndrew Lunn2017-12-281-1/+4
| | | | | | | | | | | | | | | The IRQ code already has support for lockdep class for the lock mutex in an interrupt descriptor. Extend this to add a second class for the request mutex in the descriptor. Not having a class is resulting in false positive splats in some code paths.

* pinctrl: cherryview: Mask all interrupts on Intel_Strago based systemsMika Westerberg2017-12-121-0/+16
| | | | | | | | | | | | | | | | Guenter Roeck reported an interrupt storm on a prototype system which is based on Cyan Chromebook. The root cause turned out to be a incorrectly configured pin that triggers spurious interrupts. This will be fixed in coreboot but currently we need to prevent the interrupt storm from happening by masking all interrupts (but not GPEs) on those systems.

| | | | | | | | | | | | | | | On the A80 the pins on port B can trigger interrupts, and those are assigned to the second interrupt bank. Having two pins assigned to the same interrupt bank/pin combination does not look healthy (instead more like a copy&paste bug from pins PA14-PA16), so fix the interrupt bank for pins PB14-PB16, which is actually 1.

This obviously has the implication of making the subsystem menu visible in menuconfig. This is happening because of two things: (a) Intel have started to deploy and depend on pin controllers in a way that is affecting users directly. This happens on the highly integrated laptop chipsets named after geographical places: baytrail, broxton, cannonlake, cedarfork, cherryview, denverton, geminilake, lewisburg, merrifield, sunrisepoint... It started a while back and now it is ever more evident that this is crucial infrastructure for x86 laptops and not an embedded obscurity anymore. Users need to be aware. (b) Pin control expanders on I2C and SPI that are arch-agnostic. Currently Semtech SX150X and Microchip MCP28x08 but more are expected. Users will have to be able to configure these in directly for their set-up. - Just go and select GPIOLIB now that we made sure that GPIOLIB is a very vanilla subsystem. Do not depend on it, if we need it, select it. - Exposing the pin control subsystem in menuconfig uncovered a bunch of obscure bugs that are now hopefully fixed, all more or less pertaining to Blackfin. - Unified namespace for cross-calls between pin control and GPIO. - New support for clock skew/delay generic DT bindings and generic pin config options for this. - Minor documentation improvements. Various: - The Renesas SH-PFC pin controller has evolved a lot. It seems Renesas are churning out new SoCs by the minute. - A bunch of non-critical fixes for the Rockchip driver. - Improve the use of library functions instead of open coding. - Support the MCP28018 variant in the MCP28x08 driver. - Static constifying" * tag 'pinctrl-v4.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (91 commits) pinctrl: gemini: Fix missing pad descriptions pinctrl: Add some depends on HAS_IOMEM pinctrl: samsung/s3c24xx: add CONFIG_OF dependency pinctrl: gemini: Fix GMAC groups pinctrl: qcom: spmi-gpio: Add pmi8994 gpio support pinctrl: ti-iodelay: remove redundant unused variable dev pinctrl: max77620: Use common error handling code in max77620_pinconf_set() pinctrl: gemini: Implement clock skew/delay config pinctrl: gemini: Use generic DT parser pinctrl: Add skew-delay pin config and bindings pinctrl: armada-37xx: Add edge both type gpio irq support pinctrl: uniphier: remove eMMC hardware reset pin-mux pinctrl: rockchip: Add iomux-route switching support for rk3288 pinctrl: intel: Add Intel Cedar Fork PCH pin controller support pinctrl: intel: Make offset to interrupt status register configurable pinctrl: sunxi: Enforce the strict mode by default pinctrl: sunxi: Disable strict mode for old pinctrl drivers pinctrl: sunxi: Introduce the strict flag pinctrl: sh-pfc: Save/restore registers for PSCI system suspend pinctrl: sh-pfc: r8a7796: Use generic IOCTRL register description ...

Note that as the boot loader skips most initialization after system resume, pinctrl register state differs from the state encountered during normal system boot, too. To fix this, save all GPIO and peripheral function select, module select, drive strength control, bias, and other I/O control registers during system suspend, and restore them during system resume. Note that to avoid overhead on platforms not needing it, the suspend/resume code has a build time dependency on sleep and PSCI support, and a runtime dependency on PSCI.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a generic way to describe bias registers (for pull-up/down control), like is already done for config and drive registers. This makes the sh-pfc core code aware of these registers, which will ease introducing suspend/resume support later.

| | * | pinctrl: sh-pfc: Drop width parameter of sh_pfc_{read,write}_reg()Geert Uytterhoeven2017-10-206-31/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On modern Renesas SoCs, all PFC registers are 32-bit, and all callers of sh_pfc_{read,write}_reg() already operate on 32-bit registers only. Hence make the 32-bit width implicit, and rename the functions to sh_pfc_{read,write}() to shorten lines. All accesses to 8-bit or 16-bit registers are still done using sh_pfc_{read,write}_raw_reg().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of commit 8682b3c522c639f3 ("sh-pfc: Remove platform device registration"), plain "sh-pfc" platform devices are no longer created. Hence remove their match entry, and the now obsolete checks for missing device IDs and driver data.
