* gpio: em: Use the right includeLinus Walleij2018-03-191-1/+1
| | | | | | | | The Emma Mobile (EM) GPIO driver uses the too generic include <linux/gpio.h>. It is a driver so it should just use <linux/gpio/driver.h>. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

| | | | | | | | | | This driver has no business including <linux/gpio.h>, it is a driver so include <linux/gpio/driver.h>. GPIOF_DIR_IN/GPIOF_DIR_OUT are for consumers and should not be used in drivers to use just 1/0 instead. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

| * gpio: rcar: Use wakeup_path i.s.o. explicit clock handlingGeert Uytterhoeven2018-03-051-22/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit ab82fa7da4dce5c7 ("gpio: rcar: Prevent module clock disable when wake-up is enabled"), when a GPIO is used for wakeup, the GPIO block's module clock (if exists) is manually kept running during system suspend, to make sure the device stays active. However, this explicit clock handling is merely a workaround for a failure to properly communicate wakeup information to the device core. Instead, set the device's power.wakeup_path field, to indicate this device is part of the wakeup path. Depending on the PM Domain's active_wakeup configuration, the genpd core code will keep the device enabled (and the clock running) during system suspend when needed. This allows for the removal of all explicit clock handling code from the driver. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
| * gpio: Handle deferred probing in of_find_gpio() properlyChen-Yu Tsai2018-02-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of_get_named_gpiod_flags() used directly in of_find_gpio() or indirectly through of_find_spi_gpio() or of_find_regulator_gpio() can return -EPROBE_DEFER. This gets overwritten by the subsequent of_find_*_gpio() calls. This patch fixes this by trying of_find_spi_gpio() or of_find_regulator_gpio() only if deferred probing was not requested by the previous of_get_named_gpiod_flags() call.

| * gpiolib: Keep returning EPROBE_DEFER when we shouldMaxime Ripard2018-02-271-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commits c85823390215 ("gpio: of: Support SPI nonstandard GPIO properties") and 6a537d48461d ("gpio: of: Support regulator nonstandard GPIO properties") have introduced a regression in the way error codes from of_get_named_gpiod_flags are handled. Previously, those errors codes were returned immediately, but the two commits mentioned above are now overwriting the error pointer, meaning that whatever value has been returned will be dropped in favor of whatever the two new functions will return. This might not be a big deal except for EPROBE_DEFER, on which GPIOlib customers will depend on, and that will now be returned as an hard error which means that they will not probe anymore, instead of gently deferring their probe. Since EPROBE_DEFER basically means that we have found a valid property but there was no GPIO controller registered to handle it, fix this issues by returning it as soon as we encounter it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The ISA_BUS_API Kconfig option enables the compilation of the ISA bus driver. The ISA bus driver does not perform any hardware interaction, and is instead just a thin layer of software abstraction to eliminate boilerplate code common to ISA-style device drivers. Since ISA_BUS_API has no dependencies and does not jeopardize the integrity of the system when enabled, drivers should select it when the ISA bus driver functionality is needed.

This patch is based on code developed by Albert Herranz and the GameCube Linux Team, file arch/powerpc/platforms/embedded6xx/hlwd-gpio.c, available at https://github.com/DeltaResero/GC-Wii-Linux-Kernels, but has grown quite dissimilar. v3: - Do some style cleanups, as suggest by Andy Shevchenko v2: - Change hlwd_gpio_driver.driver.name to "gpio-hlwd" to match the filename (was "hlwd_gpio") - Remove unnecessary include of linux/of_gpio.h, as suggested by Linus Walleij. - Add struct device pointer to context struct to make it possible to use dev_info(hlwd->dev, "..."), as suggested by Linus Walleij - Use the GPIO_GENERIC library to reduce code size, as suggested by Linus Walleij - Use iowrite32be instead of __raw_writel for big-endian MMIO access, as suggested by Linus Walleij - Remove commit message paragraph suggesting to diff against the original driver, because it's so different now Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net> Cc: Albert Herranz <albert_herranz@yahoo.es> Reviewed-by: Segher Boessenkool <segher@kernel.crashing.org> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Like with GPIO it is actually a bit calm this time. Core changes: - After lengthy discussions and partly due to my ignorance, we have merged a patch making pinctrl_force_default() and pinctrl_force_sleep() reprogram the states into the hardware of any hogged pins, even if they are already in the desired state. This only apply to hogged pins since groups of pins owned by drivers need to be managed by each driver, lest they could not do things like runtime PM and put pins to sleeping state even if the system as a whole is not in sleep. New drivers: - New driver for the Microsemi Ocelot SoC. This is used in ethernet switches. - The X-Powers AXP209 GPIO driver was extended to also deal with pin control and moved over from the GPIO subsystem. This circuit is a mixed-mode integrated circuit which is part of AllWinner designs. - New subdriver for the Qualcomm MSM8998 SoC, core of a high end mobile devices (phones) chipset. - New subdriver for the ST Microelectronics STM32MP157 MPU and STM32F769 MCU from the STM32 family. - New subdriver for the MediaTek MT7622 SoC. This is used for routers, repeater, gateways and such network infrastructure. - New subdriver for the NXP (former Freescale) i.MX 6ULL. This SoC has multimedia features and target "smart devices", I guess in-car entertainment, in-flight entertainment, industrial control panels etc. General improvements: - Incremental improvements on the SH-PFC subdrivers for things like the CAN bus. - Enable the glitch filter on Baytrail GPIOs used for interrupts. - Proper handling of pins to GPIO ranges on the Semtec SX150X - An IRQ setup ordering fix on MCP23S08. - A good set of janitorial coding style fixes" * tag 'pinctrl-v4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (102 commits) pinctrl: mcp23s08: fix irq setup order pinctrl: Forward declare struct device pinctrl: sunxi: Use of_clk_get_parent_count() instead of open coding pinctrl: stm32: add STM32F769 MCU support pinctrl: sx150x: Add a static gpio/pinctrl pin range mapping pinctrl: sx150x: Register pinctrl before adding the gpiochip pinctrl: sx150x: Unregister the pinctrl on release pinctrl: ingenic: Remove redundant dev_err call in ingenic_pinctrl_probe() pinctrl: sprd: Use seq_putc() in sprd_pinconf_group_dbg_show() pinctrl: pinmux: Use seq_putc() in pinmux_pins_show() pinctrl: abx500: Use seq_putc() in abx500_gpio_dbg_show() pinctrl: mediatek: mt7622: align error handling of mtk_hw_get_value call pinctrl: mediatek: mt7622: fix potential uninitialized value being returned pinctrl: uniphier: refactor drive strength get/set functions pinctrl: imx7ulp: constify struct imx_cfg_params_decode pinctrl: imx: constify struct imx_pinctrl_soc_info pinctrl: imx7d: simplify imx7d_pinctrl_probe pinctrl: imx: use struct imx_pinctrl_soc_info as a const pinctrl: sunxi-pinctrl: fix pin funtion can not be match correctly. pinctrl: qcom: Add msm8998 pinctrl driver ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We added acpi_gpiochip_pin_to_gpio_offset() because there was a need to translate from ACPI GpioIo/GpioInt number to Linux GPIO number in the Cherryview pinctrl driver. This translation is necessary because Cherryview has gaps in the pin list and the driver used continuous GPIO number space in Linux side as follows: created GPIO range 0->7 ==> INT33FF:03 PIN 0->7 created GPIO range 8->19 ==> INT33FF:03 PIN 15->26 created GPIO range 20->25 ==> INT33FF:03 PIN 30->35 created GPIO range 26->33 ==> INT33FF:03 PIN 45->52 created GPIO range 34->43 ==> INT33FF:03 PIN 60->69 created GPIO range 44->54 ==> INT33FF:03 PIN 75->85 For example when ACPI GpioInt resource refers to GPIO 81 (SDMMC3_CD_B) we translate from pin 81 to the corresponding Linux GPIO number, which is 50. This number is then used when the GPIO is accessed through gpiolib. It turns out, this is not necessary at all. We can just pass 1:1 mapping between Linux GPIO numbers and pin numbers (including gaps) and the pinctrl core handles all the details automatically: created GPIO range 0->7 ==> INT33FF:03 PIN 0->7 created GPIO range 15->26 ==> INT33FF:03 PIN 15->26 created GPIO range 30->35 ==> INT33FF:03 PIN 30->35 created GPIO range 45->52 ==> INT33FF:03 PIN 45->52 created GPIO range 60->69 ==> INT33FF:03 PIN 60->69 created GPIO range 75->85 ==> INT33FF:03 PIN 75->85 Here GPIO 81 is exactly same than the hardware pin 81 (SDMMC3_CD_B). As an added bonus this simplifies both the ACPI GPIO core code and the Cherryview pinctrl driver. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Acked-by: Rafael J.

It is pretty calm this time around I think. I even got time to get to things like starting to clean up header includes. Core changes: - Disallow open drain and open source flags to be set simultaneously. This doesn't make electrical sense, and would the hardware actually respond to this setting, the result would be short circuit. - ACPI GPIO has a new core infrastructure for handling quirks. The quirks are there to deal with broken ACPI tables centrally instead of pushing the work to individual drivers. In the world of BIOS writers, the ACPI tables are perfect. Until they find a mistake in it. When such a mistake is found, we can patch it with a quirk. It should never happen, the problem is that it happens. So we accomodate for it. - Several documentation updates. - Revert the patch setting up initial direction state from reading the device. This was causing bad things for drivers that can't read status on all its pins. It is only affecting debugfs information quality. - Label descriptors with the device name if no explicit label is passed in. - Pave the ground for transitioning SPI and regulators to use GPIO descriptors by implementing some quirks in the device tree GPIO parsing code. New drivers: - New driver for the Access PCIe IDIO 24 family. Other: - Major refactorings and improvements to the GPIO mockup driver used for test and verification. - Moved the AXP209 driver over to pin control since it gained a pin control back-end. These patches will appear (with the same hashes) in the pin control pull request as well. - Convert the onewire GPIO driver w1-gpio to use descriptors. This is merged here since the W1 maintainers send very few pull requests and he ACKed it. - Start to clean up driver headers using <linux/gpio.h> to just use <linux/gpio/driver.h> as appropriate" * tag 'gpio-v4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (103 commits) gpio: Timestamp events in hardirq handler gpio: Fix kernel stack leak to userspace gpio: Fix a documentation spelling mistake gpio: Documentation update gpiolib: remove redundant initialization of pointer desc gpio: of: Fix NPE from OF flags gpio: stmpe: Delete an unnecessary variable initialisation in stmpe_gpio_probe() gpio: stmpe: Move an assignment in stmpe_gpio_probe() gpio: stmpe: Improve a size determination in stmpe_gpio_probe() gpio: stmpe: Use seq_putc() in stmpe_dbg_show() gpio: No NULL owner gpio: stmpe: i2c transfer are forbiden in atomic context gpio: davinci: Include proper header gpio: da905x: Include proper header gpio: cs5535: Include proper header gpio: crystalcove: Include proper header gpio: bt8xx: Include proper header gpio: bcm-kona: Include proper header gpio: arizona: Include proper header gpio: amd8111: Include proper header ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a hardirq handler to the GPIO userspace event loop, making sure to pick up the timestamp there, as close as possible in time relative to the actual event causing the interrupt. Tested with a simple pushbutton GPIO on ux500 and seems to work fine.
