pinctrl: adi2: Fix Kconfig build problem

2017-12-20T09:05:00+00:00

[ Upstream commit 1c363531dd814dc4fe10865722bf6b0f72ce4673 ] The build robot is complaining on Blackfin: drivers/pinctrl/pinctrl-adi2.c: In function 'port_setup': >> drivers/pinctrl/pinctrl-adi2.c:221:21: error: dereferencing pointer to incomplete type 'struct gpio_port_t' writew(readw(®s->port_fer) & ~BIT(offset), ^~ drivers/pinctrl/pinctrl-adi2.c: In function 'adi_gpio_ack_irq': >> drivers/pinctrl/pinctrl-adi2.c:266:18: error: dereferencing pointer to incomplete type 'struct bfin_pint_regs' if (readl(®s->invert_set) & pintbit) ^~ It seems the driver need to include and to compile. The Blackfin architecture was re-defining the Kconfig PINCTRL symbol which is not OK, so replaced this with PINCTRL_BLACKFIN_ADI2 which selects PINCTRL and PINCTRL_ADI2 just like most arches do. Further, the old GPIO driver symbol GPIO_ADI was possible to select at the same time as selecting PINCTRL. This was not working because the arch-local header contains an explicit #ifndef PINCTRL clause making compilation break if you combine them. The same is true for DEBUG_MMRS. Make sure the ADI2 pinctrl driver is not selected at the same time as the old GPIO implementation. (This should be converted to use gpiolib or pincontrol and move to drivers/...) Also make sure the old GPIO_ADI driver or DEBUG_MMRS is not selected at the same time as the new PINCTRL implementation, and only make PINCTRL_ADI2 selectable for the Blackfin families that actually have it. This way it is still possible to add e.g. I2C-based pin control expanders on the Blackfin.

pinctrl: remove redundant if conditional from Kconfig

pinctrl: introduce driver for Atmel PIO4 controller

pinctrl: driver for Conexant Digicolor CX92755 pin mapping

2015-07-27T09:47:25+00:00

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 Signed-off-by: Linus Walleij

pinctrl: sirf: add sirf atlas7 pinctrl and gpio support

2015-05-19T14:01:30+00:00

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".

pinctrl: Add Pistachio SoC pin control driver

2015-05-12T11:19:41+00:00

Add a driver for the pin controller present on the IMG Pistachio SoC. This driver provides pinmux and pinconfig operations as well as GPIO and IRQ chips for the GPIO banks. Changes from v4: - Switched to using gpiochip_add_pin_range(). - Fixed up Kconfig entry. Changes from v3: - Addressed review comments from Ezequiel. Changes from v2: - Removed module stuff which would be compiled out. Changes from v1: - Addressed review comments from Linus. - Changed compatible string to "img,pistachio-system-pinctrl". - Look for GPIO sub-nodes by name. - A couple of bug fixes.
