2016-10-24pinctrl: Add SX150X GPIO Extender Pinctrl DriverNeil Armstrong1-0/+14
Since the I2C sx150x GPIO expander driver uses platform_data to manage the pins configurations, rewrite the driver as a pinctrl driver using pinconf to get/set pin configurations from DT or debugfs. The pinctrl driver is functionnally equivalent as the gpio-only driver and can use DT for pinconf. The platform_data confirmation is dropped. This patchset removed the gpio-only driver and selects the Pinctrl driver config instead. This patchset also migrates the gpio dt-bindings to pinctrl and add the pinctrl optional properties. The driver was tested with a SX1509 device on a BeagleBone black with interrupt support and on an X86_64 machine over an I2C to USB converter. This is a fixed version that builds and runs on non-OF platforms and on arm based OF. The GPIO version is removed and the bindings are also moved to the pinctrl bindings. Changes since v2 - rebased on v4.9-rc1 - removed MODULE_DEVICE_TABLE as in upstream bb411e771b0e ("gpio: sx150x: fix implicit assumption module.h is present") Changes since v1 - Fix Kconfig descriptions on pinctrl and gpio - Fix Kconfig dependency - Remove oscio support for non-789 devices - correct typo in dt bindings - remove probe reset for non-789 devices Changes since RFC - Put #ifdef CONFIG_OF/CONFIG_OF_GPIO to remove OF code for non-of platforms - No more rely on OF_GPIO config - Moved and enhanced bindings to pinctrl bindings - Removed gpio-sx150x.c - Temporary select PINCTRL_SX150X when GPIO_SX150X - Temporary mark GPIO_SX150X as deprecated Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Tested-by: Peter Rosin <peda@axentia.se> Acked-by: Rob Herring <robh@kernel.org> ested-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-09-07pinctrl: Add core support for Aspeed SoCsAndrew Jeffery1-0/+1
The Aspeed SoCs typically provide more than 200 pins for GPIO and other functions. The signal enabled on a pin is determined on a priority basis, where a given pin can provide a number of different signal types. In addition to the priority levels, the Aspeed pin controllers describe the signal active on a pin by compound logical expressions involving multiple operators, registers and bits. Some difficulty arises as a pin's function bit masks for each priority level are frequently not the same (i.e. we cannot just flip a bit to change from a high to low priority signal), or even in the same register(s). Some configuration bits affect multiple pins, while in other cases the signals for a bus must each be enabled individually. Together, these features give rise to some complexity in the implementation. A more complete description of the complexities is provided in the associated header file. The patch doesn't implement pinctrl/pinmux/pinconf for any particular Aspeed SoC, rather it adds the framework for defining pinmux configurations.

2015-05-19pinctrl: sirf: add sirf atlas7 pinctrl and gpio supportWei Chen1-0/+2
The Pinctrl module (ioc) controls the Pad's function select (each pad can have 8 functions), Pad's Drive Strength, Pad's Pull Select and Pad's Input Disable status. The ioc has two modules, ioc_top & ioc_rtc. Both of these two modules have function select/clear, Pull select and Drive Strength registers. But only ioc_rtc has input-disable registers. The Pads on ioc_top have to access ioc_rtc to set their input-disable status and intpu-disable-value. So have to use one ioc driver instance to drive these two ioc modules at the same time, and each ioc module will be treat as one bank on the "IOC Device". The GPIO Controller controls the GPIO status if the Pad has been config as GPIO by Pinctrl already. Includes the GPIO Input/output, Interrupt type, Interrupt Status, and Set/Get Values. The GPIO pull up/down are controlled by Pinctrl. There are 7 GPIO Groups and splited into 3 MACROs in atlas7. The GPIO Groups in one MACRO share one GPIO controllers, each GPIO Group are treated as one GPIO bank. For example: In VDIFM macro, there is one GPIO Controller, it has 3 banks to control 3 gpio groups. Its gpio name space is from 0 to 95. The Device Tree can be written as following: gpio-ranges = <&pinctrl 0 0 0>, <&pinctrl 32 0 0>, <&pinctrl 64 0 0>; gpio-ranges-group-names = "gnss_gpio_grp", "lcd_vip_gpio_grp", "sdio_i2s_gpio_grp"; bank#0 is from 0~31, the pins are from pinctrl's "gnss_gpio_grp". bank#2 is from 32~63, the pins are from pinctrl's "lcd_vip_gpio_grp". bank#3 is from 64~95, the pins are from pinctrl's "sdio_i2s_gpio_grp".

This was done to avoid having a custom <asm/gpio.h> header for the x86 architecture - GPIO is custom and complicated enough as it is already! We want to move to a radix to store the descriptors going forward, and finally get rid of this fixed array size altogether. - Endgame patching of the gpio_remove() semantics initiated by Abdoulaye Berthe. It is not accepted by the system that the removal of a GPIO chip fails during eg reboot or shutdown, and therefore the return value has now painfully been refactored away. For special cases like GPIO expanders on a hot-pluggable bus like USB, we may later add some gpiochip_try_remove() call, but for the cases we have now, return values are moot. - Some incremental refactoring of the gpiolib core and ACPI GPIO library for more descriptor usage. - Refactor the chained IRQ handler set-up method to handle also threaded, nested interrupts and set up the parent IRQ correctly. Switch STMPE and TC3589x drivers to use this registration method. - Add a .irq_not_threaded flag to the struct gpio_chip, so that also GPIO expanders that block but are still not using threaded IRQ handlers. - New drivers for the ARM64 X-Gene SoC GPIO controller. - The syscon GPIO driver has been improved to handle the "DSP GPIO" found on the TI Keystone 2 SoC:s. - ADNP driver switched to use gpiolib irqchip helpers. - Refactor the DWAPB driver to support being instantiated from and MFD cell (platform device). - Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP, Xilinx and Crystalcove drivers. - Various minor fixes" * tag 'gpio-v3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (52 commits) gpio: pch: Build context save/restore only for PM pinctrl: abx500: get rid of unused variable gpio: ks8695: fix 'else should follow close brace '}'' gpio: stmpe: add verbose debug code gpio: stmpe: fix up interrupt enable logic gpio: staticize xway_stp_init() gpio: handle also nested irqchips in the chained handler set-up gpio: set parent irq on chained handlers gpiolib: irqchip: use irq_find_mapping while removing irqchip gpio: crystalcove: support virtual GPIO pinctrl: bcm281xx: make Kconfig dependency more strict gpio: kona: enable only on BCM_MOBILE or for compile testing gpio, bcm-kona, LLVMLinux: Remove use of __initconst gpio: Fix ngpio in gpio-xilinx driver gpio: dwapb: fix pointer to integer cast gpio: xgene: Remove unneeded #ifdef CONFIG_OF guard gpio: xgene: Remove unneeded forward declation for struct xgene_gpio gpio: xgene: Fix missing spin_lock_init() gpio: ks8695: fix switch case indentation gpiolib: add irq_not_threaded flag to gpio_chip ...

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device-tree changes from Olof Johansson: "Unlike the board branch, this keeps having large sets of changes for every release, but that's quite expected and is so far working well. Most of this is plumbing for various device bindings and new platforms, but there's also a bit of cleanup and code removal for things that are moved from platform code to DT contents (some OMAP clock code in particular). There's also a pinctrl driver for tegra here (appropriately acked), that's introduced this way to make it more bisectable. I'm happy to say that there were no conflicts at all with this branch this release, which means that changes are flowing through our tree as expected instead of merged through driver maintainers (or at least not done with conflicts). There are several new boards added, and a couple of SoCs. In no particular order: - Rockchip RK3288 SoC support, including DTS for a dev board that they have seeded with some community developers. - Better support for Hardkernel Exynos4-based ODROID boards. - CCF conversions (and dtsi contents) for several Renesas platforms. - Gumstix Pepper (TI AM335x) board support - TI eval board support for AM437x - Allwinner A23 SoC, very similar to existing ones which mostly has resulted in DT changes for support. Also includes support for an Ippo tablet with the chipset. - Allwinner A31 Hummingbird board support, not to be confused with the SolidRun i.MX-based Hummingboard. - Tegra30 Apalis board support" * tag 'dt-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (334 commits) ARM: dts: Enable USB host0 (EHCI) on rk3288-evb ARM: dts: add rk3288 ehci usb devices ARM: dts: Turn on USB host vbus on rk3288-evb ARM: tegra: apalis t30: fix device tree compatible node ARM: tegra: paz00: Fix some indentation inconsistencies ARM: zynq: DT: Clarify Xilinx Zynq platform ARM: dts: rockchip: add watchdog node ARM: dts: rockchip: remove pinctrl setting from radxarock uart2 ARM: dts: Add missing pinctrl for uart0/1 for exynos3250 ARM: dts: Remove duplicate 'interrput-parent' property for exynos3250 ARM: dts: Add TMU dt node to monitor the temperature for exynos3250 ARM: dts: Specify MAX77686 pmic interrupt for exynos5250-smdk5250 ARM: dts: cypress,cyapa trackpad is exynos5250-Snow only ARM: dts: max77686 is exynos5250-snow only ARM: zynq: DT: Remove DMA from board DTs ARM: zynq: DT: Add CAN node ARM: EXYNOS: Add exynos5260 PMU compatible string to DT match table ARM: dts: Add PMU DT node for exynos5260 SoC ARM: EXYNOS: Add support for Exynos5410 PMU ARM: dts: Add PMU to exynos5410 ...
2014-07-28pinctrl: baytrail: Convert to use gpiolib irqchipMika Westerberg1-1/+1
Instead of open-coding irqchip handling in the driver we can take advantage of the new irqchip helpers provided by the gpiolib core. While doing this we also make sure that we call gpiochip_irqchip_add() after the gpiochip itself is registered as required.

2014-07-11pinctrl: Add NVIDIA Tegra XUSB pad controller supportThierry Reding1-0/+6
The XUSB pad controller found on NVIDIA Tegra SoCs provides several pads that lanes can be assigned to in order to support a variety of interface options: USB 2.0, USB 3.0, PCIe and SATA. In addition to the pin controller used to assign lanes to pads two PHYs are exposed to allow the bricks for PCIe and SATA to be powered up and down by PCIe and SATA drivers.

2014-05-23pinctrl: berlin: add the core pinctrl driver for Marvell Berlin SoCsAntoine Tenart1-0/+1
The Marvell Berlin boards have a group based pinmuxing mechanism. This adds the core driver support. We actually do not need any information about the pins here and only have the definition of the groups. Let's take the example of the uart0 pinmuxing on the BG2Q. Balls BK4 and BH6 are muxed to respectively UART0 RX and TX if the group GSM12 is set to mode 0: Group Modes Offset Base Offset LSB Bit Width GSM12 3 sm_base 0x40 0x10 0x2 Ball Group Mode 0 Mode 1 Mode 2 BK4 GSM12 UART0_RX IrDA0_RX GPIO9 BH6 GSM12 UART0_TX IrDA0_TX GPIO10 So in order to configure BK4 -> UART0_TX and BH6 -> UART0_RX, we need to set (sm_base + 0x40 + 0x10) &= ff3fffff. As pin control registers are part of either chip control or system control registers, that deal with a bunch of other functions we rely on a regmap instead of exclusively remapping any resources.
