We no longer have to do GPIO initialization before the pinctrl initialization, instead we can initialize the pinctrl portions of the driver first and then the GPIO. Thus we can move GPIO initialization to a subsystem_initcall(), but not yet to a device_initcall(). Signed-off-by:Linus Walleij <linus.walleij@linaro.org>

This gets the GPIO ranges out of the driver and into the device tree where they belong. Standard DT bindings already exist for this. Since no systems with this are deployed we can just augment all device trees and the drivers at the same time and simplify the world. This also defines the array of GPIO chips related to the pin controller. Cc: arm@kernel.org Acked-by:

The current interrupt parsing code was working by accident, because the default was actually parsing the first node of interrupts. While that was mostly working (and the flags were actually ignored), this binding has never been documented, and doesn't work with SoCs that have multiple interrupt banks anyway. Add a proper interrupt xlate function, that uses the same description than the GPIOs (<bank> <pin> <flags>), that will make things less confusing. The EINT number will still be used as the hwirq number, but won't be exposed through the DT. Signed-off-by:

Use dev_err() rather than pr_err() to display the error message. pinctrl_dev_get_name(pctldev) is no longer necessary because dev_err() shows which device the message is related to. Signed-off-by:

Use dev_err() rather than pr_err() to display the error message. (Besides, dev_err() is already used 7 lines below in this function.) Also, drop the redundant information "on %s" because dev_err() shows which device the message is related to. Signed-off-by:

This adds pinctrl and gpio driver to the CX92755 SoC "General Purpose Pin Mapping" hardware block. The CX92755 is one SoC from the Conexant Digicolor series. Pin mapping hardware supports configuring pins as either GPIO, or up to 3 other "client select" functions. This driver adds support for pin muxing using the generic device tree binding, and a basic gpiolib driver for the GPIO functionality. This driver does not currently support GPIO interrupts, and pad configuration. v2: * Address review comments for Linus Walleij: - Add a pointer to pinctrl_desc in struct dc_pinmap - Drop the now redundant pinctrl_pin_desc field - Adapt dc_get_group_{name,pins} to these changes, and add a comment explaining the 1-to-1 pin-groups relation * Staticise dc_pmxops * Protect the GP_CLIENTSEL clct parameter with parenthesis Signed-off-by:Baruch Siach <baruch@tkos.co.il> Signed-off-by:

If the pin controller probes before the GPIO driver it needs to populate the GPIO driver state containers ahead of the actual driver probe as the addresses are used by both halves of the driver. Signed-off-by: -

The irq argument of most interrupt flow handlers is unused or merily used instead of a local variable. The handlers which need the irq argument can retrieve the irq number from the irq descriptor. Search and update was done with coccinelle and the invaluable help of Julia Lawall.

Add the pinctrl driver for the Qualcomm Technologies QDF2xxx ARM64 SoCs, which uses the Qualcomm Technologies TLMM pinctrl/gpio device. This driver is probed via ACPI and uses the pinctrl-msm.c backend driver. This driver is intended to be used only an ACPI-enabled system. As such, UEFI will handle all pin control configuration, so this driver does not provide pin control functions. It is effectively a GPIO-only driver. Signed-off-by:

The "function" of the MPP driver was inherited from the GPIO driver, but the differences between the two hardware blocks makes both the driver and the device tree binding to be awkward. Instead of overloading the "normal" function with various modes this patch transposes the pinmux function to represent the three operating modes of the MPP (digital, analog and current sink). The properties of pin pairing and DTEST routing is moved to separate properties. Signed-off-by:
