Pull pin control updates from Linus Walleij: "This is the big bulk of pin control changes for the v4.13 series: Core: - The documentation is moved over to RST. - We now have agreed bindings for enabling input and output buffers without actually enabling input and/or output on a pin. We are chiseling out some details of pin control electronics. New drivers: - ZTE ZX - Renesas RZA1 - MIPS Ingenic JZ47xx: also switch over existing drivers in the tree to use this pin controller and consolidate earlier spread out code. - Microschip MCP23S08: this driver is migrated from the GPIO subsystem and totally rewritten to use proper pin control. All users are switched over. New subdrivers: - Renesas R8A7743 and R8A7745. - Allwinner Sunxi A83T R_PIO. - Marvell MVEBU Armada CP110 and AP806. - Intel Cannon Lake PCH. - Qualcomm IPQ8074. Notable improvements: - IRQ support on the Marvell MVEBU Armada 37xx. - Meson driver supports HDMI CEC, AO, I2S, SPDIF and PWM. - Rockchip driver now supports iomux-route switching for RK3228, RK3328 and RK3399. - Rockchip A10 and A20 are merged into a single driver. - STM32 has improved GPIO support. - Samsung Exynos drivers are split per ARMv7 and ARMv8. - Marvell MVEBU is converted to use regmap for register access. Maintenance: - Several Renesas SH-PFC refactorings and updates. - Serious code size cut for Mediatek MT7623. - Misc janitorial and MAINTAINERS fixes" * tag 'pinctrl-v4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (137 commits) pinctrl: samsung: Remove bogus irq_[un]mask from resource management pinctrl: rza1: make structures rza1_gpiochip_template and rza1_pinmux_ops static pinctrl: rza1: Remove unneeded wrong check for wrong variable pinctrl: qcom: Add ipq8074 pinctrl driver pinctrl: freescale: imx7d: make of_device_ids const. pinctrl: DT: extend the pinmux property to support integers array pinctrl: generic: Add output-enable property pinctrl: armada-37xx: Fix number of pin in sdio_sb pinctrl: armada-37xx: Fix uart2 group selection register mask pinctrl: bcm2835: Avoid warning from __irq_do_set_handler pinctrl: sh-pfc: r8a7795: Add PWM support MAINTAINERS: Add Qualcomm pinctrl drivers section arm: dts: dt-bindings: Add Renesas RZ/A1 pinctrl header dt-bindings: pinctrl: Add RZ/A1 bindings doc pinctrl: Renesas RZ/A1 pin and gpio controller pinctrl: sh-pfc: r8a7792: Add SCIF1 and SCIF2 pin groups pinctrl.txt: move it to the driver-api book pinctrl: ingenic: checking for NULL instead of IS_ERR() pinctrl: uniphier: fix WARN_ON() of pingroups dump on LD20 pinctrl: uniphier: fix WARN_ON() of pingroups dump on LD11 ...

spi: Generalize SPI "master" to "controller"

2017-06-13T17:51:11Z

Now struct spi_master is used for both SPI master and slave controllers, it makes sense to rename it to struct spi_controller, and replace "master" by "controller" where appropriate. For now this conversion is done for SPI core infrastructure only. Wrappers are provided for backwards compatibility, until all SPI drivers have been converted. Noteworthy details: - SPI_MASTER_GPIO_SS is retained, as it only makes sense for SPI master controllers, - spi_busnum_to_master() is retained, as it looks up masters only, - A new field spi_device.controller is added, but spi_device.master is retained for compatibility (both are always initialized by spi_alloc_device()), - spi_flash_read() is used by SPI masters only.

spi: sh-msiof: Add slave mode support

2017-05-26T12:11:54Z

Add slave mode support to the MSIOF driver, in both PIO and DMA mode. For now this only supports the transmission of messages with a size that is known in advance.

spi: core: Add support for registering SPI slave controllers

2017-05-26T12:11:00Z

Add support for registering SPI slave controllers using the existing SPI master framework: - SPI slave controllers must use spi_alloc_slave() instead of spi_alloc_master(), and should provide an additional callback "slave_abort" to abort an ongoing SPI transfer request, - SPI slave controllers are added to a new "spi_slave" device class, - SPI slave handlers can be bound to the SPI slave device represented by an SPI slave controller using a DT child node named "slave", - Alternatively, (un)binding an SPI slave handler to the SPI slave device represented by an SPI slave controller can be done by (un)registering the slave device through a sysfs virtual file named "slave". From the point of view of an SPI slave protocol handler, an SPI slave controller looks almost like an ordinary SPI master controller. The only exception is that a transfer request will block on the remote SPI master, and may be cancelled using spi_slave_abort(). Signed-off-by: Geert Uytterhoeven Signed-off-by: Mark Brown

pinctrl: mcp23s08: fix comment for mcp23s08_platform_data.base

2017-05-23T07:51:33Z

The comment does not match the driver, which actually supports automatic assignment. Fix this by updating the comment. Signed-off-by: Sebastian Reichel Signed-off-by: Linus Walleij

pinctrl: mcp23s08: drop comment about missing irq support

2017-05-23T07:51:08Z

The driver supports using mcp23xxx as interrupt controller, so let's drop all comments stating otherwise. Signed-off-by: Sebastian Reichel Signed-off-by: Linus Walleij

pinctrl: mcp23s08: generalize irq property handling

2017-05-23T07:50:13Z

This moves irq property handling from spi/i2c specific code into the generic mcp23s08_probe_one. This is possible because the device properties are named equally. As a side-effect this drops support for setting the properties via pdata, which has no mainline users. If boardcode wants to enable the chip as interrupt controller it can attach the device properties instead. Signed-off-by: Sebastian Reichel Signed-off-by: Linus Walleij

pinctrl: mcp23s08: drop pullup config from pdata

2017-05-23T07:47:03Z

mcp23s08 support configuration of the pullups using the pinconf framework. This removes the custom pullup configuration from platform data, which has no upstream users. Signed-off-by: Sebastian Reichel Signed-off-by: Linus Walleij
