pinctrl: mediatek: Use real dependencies

2017-01-26T15:26:50+00:00

Do not hide pinctrl drivers for Mediatek platforms using conditionals. Doing so actually leaves the symbols present (but always disabled) on all other platforms, which is confusing and inefficient. Better use real dependencies so that the symbols do not exist at all on platforms where they are not relevant.

pinctrl / gpio: Introduce .set_config() callback for GPIO chips

2017-01-26T14:27:37+00:00

Currently we already have two pin configuration related callbacks available for GPIO chips .set_single_ended() and .set_debounce(). In future we expect to have even more, which does not scale well if we need to add yet another callback to the GPIO chip structure for each possible configuration parameter. Better solution is to reuse what we already have available in the generic pinconf. To support this, we introduce a new .set_config() callback for GPIO chips. The callback takes a single packed pin configuration value as parameter. This can then be extended easily beyond what is currently supported by just adding new types to the generic pinconf enum. If the GPIO driver is backed up by a pinctrl driver the GPIO driver can just assign gpiochip_generic_config() (introduced in this patch) to .set_config and that will take care configuration requests are directed to the pinctrl driver. We then convert the existing drivers over .set_config() and finally remove the .set_single_ended() and .set_debounce() callbacks.

pinctrl: mt8173: set GPIO16 to usb iddig mode

2016-12-07T14:27:01+00:00

pinctrl: mediatek: constify gpio_chip structures

2016-09-13T08:39:33+00:00

These structures are only used to copy into other structures, so declare them as const. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @r disable optional_qualifier@ identifier i; position p; @@ static struct gpio_chip i@p = { ... }; @ok@ identifier r.i; expression e; position p; @@ e = i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct gpio_chip e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct gpio_chip i = { ... }; // Signed-off-by: Julia Lawall Signed-off-by: Linus Walleij

pinctrl: mediatek: make mtk-common explicitly non-modular

2016-08-27T11:11:53+00:00

The Makefile currently controlling compilation of this code is: drivers/pinctrl/mediatek/pinctrl-mtk-common.o ---> drivers/pinctrl/mediatek/Makefile:obj-y += pinctrl-mtk-common.o ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We don't replace module.h with init.h since the file doesn't need that.

Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v4.8 kernel cycle. Nothing stands out as especially exiting: new drivers, new subdrivers, lots of cleanups and incremental features. Business as usual. New drivers: - New driver for Oxnas pin control and GPIO. This ARM-based chipset is used in a few storage (NAS) type devices. - New driver for the MAX77620/MAX20024 pin controller portions. - New driver for the Intel Merrifield pin controller. New subdrivers: - New subdriver for the Qualcomm MDM9615 - New subdriver for the STM32F746 MCU - New subdriver for the Broadcom NSP SoC. Cleanups: - Demodularization of bool compiled-in drivers. Apart from this there is just regular incremental improvements to a lot of drivers, especially Uniphier and PFC" * tag 'pinctrl-v4.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (131 commits) pinctrl: fix pincontrol definition for marvell pinctrl: xway: fix typo Revert "pinctrl: amd: make it explicitly non-modular" pinctrl: iproc: Add NSP and Stingray GPIO support pinctrl: Update iProc GPIO DT bindings pinctrl: bcm: add OF dependencies pinctrl: ns2: remove redundant dev_err call in ns2_pinmux_probe() pinctrl: Add STM32F746 MCU support pinctrl: intel: Protect set wake flow by spin lock pinctrl: nsp: remove redundant dev_err call in nsp_pinmux_probe() pinctrl: uniphier: add Ethernet pin-mux settings sh-pfc: Use PTR_ERR_OR_ZERO() to simplify the code pinctrl: ns2: fix return value check in ns2_pinmux_probe() pinctrl: qcom: update DT bindings with ebi2 groups pinctrl: qcom: establish proper EBI2 pin groups pinctrl: imx21: Remove the MODULE_DEVICE_TABLE() macro Documentation: dt: Add new compatible to STM32 pinctrl driver bindings includes: dt-bindings: Add STM32F746 pinctrl DT bindings pinctrl: sunxi: fix nand0 function name for sun8i pinctrl: uniphier: remove pointless pin-mux settings for PH1-LD11 ...

pinctrl: mediatek: fix suspend/resume timing issue

2016-06-08T08:09:40+00:00

An irq which is a wake up source maybe masked unexpectedly if the wake up source irq was triggered after pinctrl irqchip suspend and before suspend_device_irqs finished. Use *_noirq callbacks to guarantee pinctrl irqchip suspend would be called after suspend_devices_irqs. Signed-off-by: hongkun.cao Signed-off-by: Linus Walleij
