After updating to a more recent version of the Armada XP datasheet, we realized that some of the pins documented as having a NAND-related functionality in fact did not have such functionality. This commit updates the pinctrl driver accordingly. Signed-off-by:

Due to a mistake, the CS0 and CS1 SPI0 functions were incorrectly named "spi0-1" instead of just "spi0". This commit fixes that. This DT binding change does not affect any of the in-tree users. Signed-off-by:

A new revision of the Marvell Armada 38x hardware datasheet unveiled that the definition of some of the PCIe functions were not correct. This commit fixes the pinctrl driver accordingly. Some PCIe functions simply do not exist, some of the PCIe functions in fact were corresponding to other functions, and some PCIe functions have been added. Note: the seemingly unrelated removal of spi(cs2) on MPP47 is related: this function is in fact implemented on MPP43, instead of a PCIe function. Signed-off-by:

There is no reason to try to print groups associated to a function if get_function_groups returns an error. Moreover, it can lead to a NULL pointer dereference error. Signed-off-by:

There are two types for pinctrl maps: pinmux and pinconfig This debug message shows the number of maps of both types. The string "pinmux map" is not precise. Let's say "pinctrl map" instead. Signed-off-by:

Since mt6397 is no need to support interrupt controller, I judged "interrupt-controller" property to skip it last patch. But the if judgement should on the contrary, this is a bug. And find of_property_read_bool is better for this case. So using of_property_read_bool instead of of_find_property. Also fix bug of misuse pointer. Signed-off-by:

Commit e5b3b2d9 ("pinctrl: allows not to define the get_group_pins operation") allows pin controllers not to register the get_group_pins() function. However, a side-effect of not registering this function is that pins are not allocated and potentially multiple devices could attempt to configure the same pins [1]. Although this problem exists in the pinctrl core, because only a few devices are impacted by this, fix this for tegra-xusb by adding the get_group_pins() function. Please note that in addition to adding the get_group_pins() functions the pins/lanes for the tegra-xusb also need to be registered when calling pinctrl_register(). This also allows the current pinmux state to be viewed by the debugfs node "pinmux-pins" for the tegra-xusb pad controller. [1] http://www.spinics.net/lists/linux-gpio/msg05810.htmlSigned-off-by:

If we know we are using a strict pin controller (one that cannot mix device functions+group use and GPIO) we can be a bit more specific in debugfs, just print either device-function-group or GPIO consumer for the pin. Let's do that to be helpful. Cc: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by:

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".

Add mt6397 support using mediatek common pinctrl driver. mt6397 is a PMIC, and pinctrl/GPIO is part of 6397 chip. Pinctrl/GPIO driver should obtain regmap from PMIC, so adding this support to common code. Also, mt6397 is no need to support interrupt controller, so changing common code to skip it. Signed-off-by:

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. Signed-off-by:
