2017-08-14gpio: rcar: add gen[123] fallback compatibility stringsSimon Horman1-4/+11
Add fallback compatibility string for R-Car Gen 1, 2 and 3. In the case of Renesas R-Car hardware we know that there are generations of SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship between IP blocks might be. For example, I believe that r8a7790 is older than r8a7791 but that doesn't imply that the latter is a descendant of the former or vice versa. We can, however, by examining the documentation and behaviour of the hardware at run-time observe that the current driver implementation appears to be compatible with the IP blocks on SoCs within a given generation. For the above reasons and convenience when enabling new SoCs a per-generation fallback compatibility string scheme being adopted for drivers for Renesas SoCs. Also deprecate renesas,gpio-rcar as its name is more generic than its implementation.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.13 series. Some administrativa: I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO driver coming in through this tree, along with a whole bunch of Exar 8250 fixes. These are ACKed by Greg and also hit drivers/platform/* where they are ACKed by Andy Shevchenko. Speaking about drivers/platform/* there is also a bunch of ACPI stuff coming through that route, again ACKed by Andy. The MCP23S08 changes are coming in here as well. You already have the commits in your tree, so this is just a result of sharing an immutable branch between pin control and GPIO. Core: - Export add/remove for lookup tables so that modules can export GPIO descriptor tables. - Handle GPIO sleep states: it is now possible to flag that a GPIO line may loose its state during suspend/resume of the system to save power. This is used in the Wolfson Micro Arizona driver. - ACPI-based GPIO was tightened up a lot around the edges. - Use bitmap_fill() to speed up a loop. New drivers: - Exar XRA1403 SPI-based GPIO. - MVEBU driver now supports Armada 7K and 8K. - LP87565 PMIC GPIO. - Renesas R-CAR R8A7743 (RZ/G1M). - The new IOT2040 8250 serial/GPIO also comes in through this changeset. Substantial driver changes: - Seriously fix the Exar 8250 GPIO portions to work. - The MCP23S08 was moved out to a pin control driver. - Convert MEVEBU to use regmap for register access. - Drop Vulcan support from the Broadcom driver. - Serious cleanup and improvement of the mockup driver, giving us a better test coverage.

As such "marvell,armada-370-xp-gpio" for the compatible string is a misnomer. Change the compatible string to "marvell,armada-370-gpio" before the driver makes it out of the -rc stage.

2017-04-24gpio: mvebu: Add limited PWM supportAndrew Lunn1-0/+32
Armada 370/XP devices can 'blink' GPIO lines with a configurable on and off period. This can be modelled as a PWM. However, there are only two sets of PWM configuration registers for all the GPIO lines. This driver simply allows a single GPIO line per GPIO chip of 32 lines to be used as a PWM. Attempts to use more return EBUSY. Due to the interleaving of registers it is not simple to separate the PWM driver from the GPIO driver. Thus the GPIO driver has been extended with a PWM driver.

Add optional reset-gpios pin control. If present, de-assert the specified reset gpio pin to bring the chip out of reset. v2: - Specify that reset signal to PCA953x chip is active low, in binding doc. - reorder includes in gpio-pca953x.c. - remove dev_err() on devm_gpiod_get_optional() error return.

2016-12-30gpio: of: Add support for multiple GPIOs in a single GPIO hogGeert Uytterhoeven1-4/+4
When listing multiple GPIOs in the "gpios" property of a GPIO hog, only the first GPIO is affected. The user is left clueless about the dysfunctioning of the other GPIOs specified. Fix this by adding and documenting support for specifying multiple GPIOs in a single GPIO hog.

From the driver code, the second cell specifies the standard flags as described in gpio.txt.

2016-10-24pinctrl: Add SX150X GPIO Extender Pinctrl DriverNeil Armstrong1-41/+0
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>
