2018-11-13pinctrl: sh-pfc: r8a7792: Fix VIN versioned groupsJacopo Mondi
Versioned VIN groups can appear on different sets of pins. Using the VIN_DATA_PIN_GROUP macro now supports proper naming of said groups through an optional 'version' argument. Use the 'version' argument for said macro to fix naming of versioned groups for the R-Car V2H R8A7792 SoC.

2018-11-13pinctrl: sh-pfc: Add optional arg to VIN_DATA_PIN_GROUPJacopo Mondi
VIN data groups may appear on different sets of pins, usually named "vinX_data_[a|b]". The existing VIN_DATA_PIN_GROUP() does not support appending the '_a' or '_b' suffix, leading to the definition of group names not consistent with the ones defined using the SH_PFC_PIN_GROUP() macro. Fix this by making the VIN_DATA_PIN_GROUP macro a variadic one, which accepts an optional 'version' argument.

2018-11-09pinctrl: fsl: imx7ulp: change to use imx legacy bindingA.s. Dong
We already had an earlier conclusion that all new i.MX Socs will keep using the legacy i.MX Pinctrl bindings instead of generic pin config. However, MX7ULP generic pin config binding support has already been in tree before that time. Per SoC maintainers' suggestions, in order to get a better consistency for all i.MX devices, we'd like to go back to imx legacy binding for MX7ULP as well.

2018-11-09pinctrl: qcom: spmi-gpio: fix gpio-hog related boot issuesBrian Masney
When attempting to setup up a gpio hog, device probing would repeatedly fail with -EPROBE_DEFERED errors. It was caused by a circular dependency between the gpio and pinctrl frameworks. If the gpio-ranges property is present in device tree, then the gpio framework will handle the gpio pin registration and eliminate the circular dependency. See Christian Lamparter's commit a86caa9ba5d7 ("pinctrl: msm: fix gpio-hog related boot issues") for a detailed commit message that explains the issue in much more detail.

2018-11-05pinctrl: bcm2835: Use raw spinlock for RT compatibilityLukas Wunner
The BCM2835 pinctrl driver acquires a spinlock in its ->irq_enable, ->irq_disable and ->irq_set_type callbacks. Spinlocks become sleeping locks with CONFIG_PREEMPT_RT_FULL=y, therefore invocation of one of the callbacks in atomic context may cause a hard lockup if at least two GPIO pins in the same bank are used as interrupts. The issue doesn't occur with just a single interrupt pin per bank because the lock is never contended. I'm experiencing such lockups with GPIO 8 and 28 used as level-triggered interrupts, i.e. with ->irq_disable being invoked on reception of every IRQ. The critical section protected by the spinlock is very small (one bitop and one RMW of an MMIO register), hence converting to a raw spinlock seems a better trade-off than converting the driver to threaded IRQ handling (which would increase latency to handle an interrupt).
