2017-12-20pinctrl: rockchip: enable clock when reading pin direction registerBrian Norris1-0/+8
We generally leave the GPIO clock disabled, unless an interrupt is requested or we're accessing IO registers. We forgot to do this for the ->get_direction() callback, which means we can sometimes [1] get incorrect results [2] from, e.g., /sys/kernel/debug/gpio. Enable the clock, so we get the right results! [1] Sometimes, because many systems have 1 or mor interrupt requested on each GPIO bank, so they always leave their clock on. [2] Incorrect, meaning the register returns 0, and so we interpret that as "input".

2017-12-20pinctrl: mediatek: add pinctrl driver for MT7622 SoCSean Wang4-2/+1608
Add support for pinctrl on MT7622 SoC. The IO core found on the SoC has the registers for pinctrl, pinconf and gpio mixed up in the same register range. However, the IO core for the MT7622 SoC is completely distinct from anyone of previous MediaTek SoCs which already had support, such as the hardware internal, register address map and register detailed definition for each pin. Therefore, instead, the driver is being newly implemented by reusing generic methods provided from the core layer with GENERIC_PINCONF, GENERIC_PINCTRL_GROUPS, and GENERIC_PINMUX_FUNCTIONS for the sake of code simplicity and rid of superfluous code. Where the function of pins determined by groups is utilized in this driver which can help developers less confused with what combinations of pins effective on the SoC and even reducing the mistakes during the integration of those relevant boards. As the gpio_chip handling is also only a few lines, the driver also implements the gpio functionality directly through GPIOLIB.

2017-12-20pinctrl: Really force states during suspend/resumeFlorian Fainelli1-7/+17
In case a platform only defaults a "default" set of pins, but not a "sleep" set of pins, and this particular platform suspends and resumes in a way that the pin states are not preserved by the hardware, when we resume, we would call pinctrl_single_resume() -> pinctrl_force_default() -> pinctrl_select_state() and the first thing we do is check that the pins state is the same as before, and do nothing. In order to fix this, decouple the actual state change from pinctrl_select_state() and move it pinctrl_commit_state(), while keeping the p->state == state check in pinctrl_select_state() not to change the caller assumptions. pinctrl_force_sleep() and pinctrl_force_default() are updated to bypass the state check by calling pinctrl_commit_state(). [Linus Walleij] The forced pin control states are currently only used in some pin controller drivers that grab their own reference to their own pins. This is equal to the pin control hogs: pins taken by pin control devices since there are no corresponding device in the Linux device hierarchy, such as memory controller lines or unused GPIO lines, or GPIO lines that are used orthogonally from the GPIO subsystem but pincontrol-wise managed as hogs (non-strict mode, allowing simultaneous use by GPIO and pin control). For this case forcing the state from the drivers' suspend()/resume() callbacks makes sense and should semantically match the name of the function.

2017-12-02pinctrl: intel: Initialize GPIO properly when used through irqchipMika Westerberg1-8/+15
When a GPIO is requested using gpiod_get_* APIs the intel pinctrl driver switches the pin to GPIO mode and makes sure interrupts are routed to the GPIO hardware instead of IOAPIC. However, if the GPIO is used directly through irqchip, as is the case with many I2C-HID devices where I2C core automatically configures interrupt for the device, the pin is not initialized as GPIO. Instead we rely that the BIOS configures the pin accordingly which seems not to be the case at least in Asus X540NA SKU3 with Focaltech touchpad. When the pin is not properly configured it might result weird behaviour like interrupts suddenly stop firing completely and the touchpad stops responding to user input. Fix this by properly initializing the pin to GPIO mode also when it is used directly through irqchip.

2017-11-30pinctrl: meson-axg: Introduce a pinctrl pinmux ops for Meson-AXG SoCXingyu Chen5-0/+185
The pin controller has been updated in the Amlogic Meson AXG series, which use continuous 4-bit register to select function for each pin. In order to support this, a new pinmux operations "meson_axg_pmx_ops" has been added.

2017-11-29pinctrl: mcp23s08: Improve unlocking of a mutex in mcp23s08_irq()Markus Elfring1-20/+15
* Add a jump target so that a call of the function "mutex_unlock" is stored only twice in this function implementation. * Replace five calls by goto statements. * Adjust five condition checks. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2017-11-29pinctrl: cannonlake: Align GPIO number space with WindowsMika Westerberg1-31/+34
The Cannon Lake Windows GPIO driver always exposes 32 pins per "bank" regardless of whether the hardware actually has that many pins in a pad group. This means that there are gaps in the GPIO number space even if such gaps do not exist in the real hardware. To make things worse the BIOS is also using the same scheme, so for example on Cannon Lake-LP vGPIO 39 (vSD3_CD_B) the ACPI GpioInt resource has number 231 instead of the expected 180 (which would be the hardware number). To make SD card detection and other GPIOs working properly in Linux we align the pinctrl-cannonlake GPIO numbering to follow the Windows GPIO driver numbering taking advantage of the gpio_base field introduced in the previous patch.
