2017-08-21pinctrl: Add pinctrl driver for the RK805 PMICJoseph Chen3-0/+503
RK805 is one of Rockchip PMICs family, it has 2 output only GPIOs. This driver is also designed for other Rockchip PMICs to expend. Different PMIC maybe have different pin features, for example, RK816 has one pin which can be used for TS or GPIO(input/out). The mainly difference between PMICs pins are pinmux, direction and output value, that is 'struct rk805_pin_config'.

2017-08-07pinctrl: armada-37xx: Fix the pin 23 on south bridgeGregory CLEMENT1-6/+17
Pin 23 on South bridge does not belong to the rgmii group. It belongs to a separate group which can have 3 functions. Due to this the fix also have to update the way the functions are managed. Until now each groups used NB_FUNCS(which was 2) functions. For the mpp23, 3 functions are available but it is the only group which needs it, so on the loop involving NB_FUNCS an extra test was added to handle only the functions added. The bug was visible with the merge of the commit 07d065abf93d "arm64: dts: marvell: armada-3720-db: Add vqmmc regulator for SD slot", the gpio regulator used the gpio 23, due to this the whole rgmii group was setup to gpio which broke the Ethernet support on the Armada 3720 DB board. Thanks to this patch, the UHS SD cards (which need the vqmmc) _and_ the Ethernet work again.

2017-08-01pinctrl: stm32: select IRQ_DOMAIN_HIERARCHY instead of depends onMasahiro Yamada1-4/+5
Drivers that need IRQ_DOMAIN_HIERARCHY should "select" it, but drivers/pinctrl/stm32/Kconfig is the only exception that uses "depends on" syntax. This prevents GPIO drivers from select'ing IRQ_DOMAIN_HIERARCHY. For example, if I add "select IRQ_DOMAIN_HIERARCHY" to GPIO_XGENE_SB, I get the following recursive dependency error. drivers/gpio/Kconfig:13:error: recursive dependency detected!

2017-07-31pinctrl: sunxi: add a missing function of A10/A20 pinctrl driverIcenowy Zheng1-0/+1
The PH16 pin has a function with mux id 0x5, which is the DET pin of the "sim" (smart card reader) IP block. This function is missing in old versions of A10/A20 SoCs' datasheets and user manuals, so it's also missing in the old drivers. The newest A10 Datasheet V1.70 and A20 Datasheet V1.41 contain this pin function, and it's discovered during implementing R40 pinctrl driver. Add it to the driver. As we now merged A20 pinctrl driver to the A10 one, we need to only fix the A10 driver now.

2017-06-30pinctrl: samsung: Remove bogus irq_[un]mask from resource managementThomas Gleixner1-4/+0
The irq chip callbacks irq_request/release_resources() have absolutely no business with masking and unmasking the irq. The core code unmasks the interrupt after complete setup and masks it before invoking irq_release_resources(). The unmask is actually harmful as it happens before the interrupt is completely initialized in __setup_irq(). Remove it.

This commit adds a pinctrl driver for the CP110 part of the Marvell Armada 7K and 8K SoCs. The Armada 7K has a single CP110, where almost all the MPP pins are available. On the other side, the Armada 8K has two CP110, and the available MPPs are split between the master CP110 (MPPs 32 to 62) and the slave CP110 (MPPs 0 to 31). The register interface to control the MPPs is however the same as all other mvebu SoCs, so we can reuse the common pinctrl-mvebu.c logic.

2017-06-09pinctrl: intel: Add support for variable size pad groupsMika Westerberg3-56/+176
The Intel GPIO hardware has a concept of pad groups, which means 1 to 32 pads occupying their own GPI_IS, GPI_IE, PAD_OWN and so on registers. The existing hardware has the same amount of pads in each pad group (except the last one) so it is possible to use community->gpp_size to calculate start offset of each register. With the next generation SoCs the pad group size is not always the same anymore which means we cannot use community->gpp_size for register offset calculations directly. To support variable size pad groups we introduce struct intel_padgroup that can be filled in by the client drivers according the hardware pad group layout. The core driver will always use these when it performs calculations for pad register offsets. The core driver will automatically populate pad groups based on community->gpp_size if the driver does not provide any. This makes sure the existing drivers still work as expected.

2017-06-09pinctrl/amd: Use regular interrupt instead of chainedThomas Gleixner1-50/+41
The AMD pinctrl driver uses a chained interrupt to demultiplex the GPIO interrupts. Kevin Vandeventer reported, that his new AMD Ryzen locks up hard on boot when the AMD pinctrl driver is initialized. The reason is an interrupt storm. It's not clear whether that's caused by hardware or firmware or both. Using chained interrupts on X86 is a dangerous endavour. If a system is misconfigured or the hardware buggy there is no safety net to catch an interrupt storm. Convert the driver to use a regular interrupt for the demultiplex handler. This allows the interrupt storm detector to catch the malfunction and lets the system boot up. This should be backported to stable because it's likely that more users run into this problem as the AMD Ryzen machines are spreading.
