2017-01-03pinctrl: core: Use delayed work for hogsTony Lindgren
Having the pin control framework call pin controller functions before it's probe has finished is not nice as the pin controller device driver does not yet have struct pinctrl_dev handle. Let's fix this issue by adding deferred work for late init. This is needed to be able to add pinctrl generic helper functions that expect to know struct pinctrl_dev handle. Note that we now need to call create_pinctrl() directly as we don't want to add the pin controller to the list of controllers until the hogs are claimed. We also need to pass the pinctrl_dev to the device tree parser functions as they otherwise won't find the right controller at this point.

2016-12-30pinctrl: imx: use radix trees for groups and functionsGary Bisson
This change is inspired from the pinctrl-single architecture. The problem with current implementation is that it isn't possible to add/remove functions and/or groups dynamically. The radix tree offers an easy way to do so. The intent is to offer a follow-up patch later that will enable the use of pinctrl nodes in dt-overlays.

2016-12-27pinctrl: aspeed: Read and write bits in LPC and GFX controllersAndrew Jeffery
The System Control Unit IP block in the Aspeed SoCs is typically where the pinmux configuration is found, but not always. A number of pins depend on state in one of LPC Host Control (LHC) or SoC Display Controller (GFX) IP blocks, so the Aspeed pinmux drivers should have the means to adjust these as necessary. We use syscon to cast a regmap over the GFX and LPC blocks, which is used as an arbitration layer between the relevant driver and the pinctrl subsystem. The regmaps are then exposed to the SoC-specific pinctrl drivers by phandles in the devicetree, and are selected during a mux request by querying a new 'ip' member in struct aspeed_sig_desc.

2016-12-07pinctrl: bcm2835: switch to GPIOLIB_IRQCHIPLinus Walleij
It should be possible to use the GPIOLIB_IRQCHIP helper library with the BCM2835 driver since it is a pretty straight forward cascaded irqchip. The only difference from other drivers is that the BCM2835 has several banks for a single gpiochip, and each bank has a separate IRQ line. Instead of creating one gpiochip per bank, a single gpiochip covers all banks GPIO lines. This makes it necessary to resolve the bank ID in the IRQ handler. The GPIOLIB_IRQCHIP allows several IRQs to be cascaded off the same gpiochip by calling gpiochip_set_chained_irqchip() repeatedly, but we have been a bit short on examples for how this should be handled in practice, so this is intended as an example of how this can be achieved. The old code did not model the chip as a chained interrupt handler, but this patch also rectifies that situation.

Finally he adds support for the TP-LINK Archer C9 V1 router. - Kamal adds support for the QSPI controller on the Northstar Plus SoCs and updates the bcm958625k reference board to have it enabled - Dan adds support for the Luxul XAP-1510 (using a BCM4708) and XWR-3100 (using a BCM47094) - Scott fixes the pinctrl names in the Cygnus DTS files - Jonathan enables the Broadcom iProc mailbox controller for Broadcom Cygnus/iProc SoCs, he adds interrupt support for the GPIO CRMU hardware block and finally adds the node for the OTP controller found on Cygnus SoCs - Dhananjay enables the GPIO B controller on Norstarh Plus SoCs - Eric defines standard pinctrl groups in the BCM2835 GPIO node - Gerd adds definitions for the pinctrl groups and updates the PWM, I2C and SDHCI nodes to use their appropriate pinctrl functions - Linus adds names for the Raspberry Pi GPIO lines based on the datasheet - Martin adds the DT binding and nodes for the Raspberry Pi firmware thermal block - Stefan fixes a few typos with respect to the BCM2835 mailbox binding example and Device Tree nodes he also fixes the Raspberry Pi GPIO lines names and finally adds names for the Raspberry Zero GPIO lines * tag 'arm-soc/for-4.10/devicetree' of http://github.com/Broadcom/stblinux: (29 commits) ARM: bcm2835: Add names for the RPi Zero GPIO lines ARM: bcm2835: Fix names for the Raspberry Pi GPIO lines ARM: dts: enable GPIO-b for Broadcom NSP ARM: BCM5301X: Add DT for TP-LINK Archer C9 V1 ARM: dts: Add node for Broadcom OTP controller driver ARM: dts: Enable interrupt support for cygnus crmu gpio driver ARM: dts: Enable Broadcom iProc mailbox controller ARM: bcm2835: Add names for the Raspberry Pi GPIO lines ARM: bcm2835: dts: add thermal node to device-tree of bcm283x dt: bindings: add thermal device driver for bcm2835 ARM: dts: bcm283x: fix typo in mailbox address DT: binding: bcm2835-mbox: fix address typo in example ARM: dts: cygnus: fix naming of pinctrl node ARM: BCM53573: Specify PMU and its ILP clock in the DT ARM: BCM5301X: Add DT for Luxul XWR-3100 ARM: BCM5301X: Add DT for Luxul XAP-1510 ARM: BCM5301X: Specify USB 3.0 PHY in DT ARM: BCM5301X: Enable UART on Netgear R8000 ARM: BCM5301X: Add separated DTS include file for BCM47094 ARM: dts: NSP: Add QSPI nodes to NSPI and bcm958625k DTSes ...

2016-11-25pinctrl: sx150x: use correct registers for reg_sense (sx1502 and sx1508)Peter Rosin
All other registers on these chips are 8-bit, but reg_sense is 16-bits and therefore needs to be moved down one notch. This was apparently overlooked in the conversion to regmap, which only updated the register locations for the 16-bit chips.

2016-11-24pinctrl: sx150x: support setting multiple pins at oncePeter Rosin
If the chip does not have an oscio pin, all pins are configured in the same regmap register making it trivial to update all pins at once, so do that. If an oscio pin is present, there needs to be more locking in place to handle all cases correctly, so this is skipped.

2016-11-22pinctrl: sunxi: Testing the wrong variableDan Carpenter
Smatch complains that we dereference "map" before testing it for NULL which is true. We should be testing "*map" instead. Also on the error path, we should free *map and set it to NULL.
