pinctrl: mediatek: select GPIOLIB

2018-10-10T11:53:21+00:00

Removing the linux/gpio.h include means we no longer have a declaration
of gpiochip_lock_as_irq() when CONFIG_GPIOLIB is disabled:

drivers/pinctrl/mediatek/mtk-eint.c: In function 'mtk_eint_irq_request_resources':
drivers/pinctrl/mediatek/mtk-eint.c:247:8: error: implicit declaration of function 'gpiochip_lock_as_irq'; did you mean 'spin_lock_irq'? [-Werror=implicit-function-declaration]
drivers/pinctrl/mediatek/mtk-eint.c: In function 'mtk_eint_irq_release_resources':
drivers/pinctrl/mediatek/mtk-eint.c:272:2: error: implicit declaration of function 'gpiochip_unlock_as_irq'; did you mean 'spin_unlock_irq'? [-Werror=implicit-function-declaration]

Select it explictly instead.

pinctrl: mediatek: add pinctrl-paris that implements the vendor dt-bindings

2018-09-18T21:53:25+00:00

Add pinctrl-paris core that implements vendor dt-binding which MediaTek
tablet, box and smartphone-based SoCs such as MT81xx, MT27xx, and MT67xx
SoCs really want to depend on. The driver is just completely rewritten
according to pinctrl-mtk-common.c but uses the new logic from
pinctrl-mtk-common-v2.c to have an elegant way to support new SoCs in the
future.

pinctrl: mediatek: add MT7623 pinctrl driver based on generic pinctrl binding

2018-09-18T21:53:05+00:00

Adding MT7623 pinctrl driver based on generic pinctrl binding, that is
good example and demonstrates how to port any other MediaTek SoCs
pinctrl-moore core when people really would like to use the generic
pinctrl binding to support these MediaTek SoCs.

pinctrl: mediatek: add pinctrl-moore that implements the generic pinctrl dt-bindings

2018-09-18T21:52:37+00:00

Add a generic driver pinctrl-moore.c for MT762x SoC and any other SoC
that would like to use generic dt-binding. The patch is furtherly
refactored from pinctrl-mt7622.c that totally uses the functions back by
the generic pinctrl core such as GENERIC_PINCONF, GENERIC_PINCTRL_GROUPS,
and GENERIC_PINMUX_FUNCTIONS and its binding also completely follows up
pinctrl-bindings.txt in Documentation/devicetree/bindings/pinctrl/ to
implement.

pinctrl: mediatek: refactor EINT related code for all MediaTek pinctrl can fit

2018-05-24T07:37:21+00:00

This patch is in preparation for adding EINT support to MT7622 pinctrl,
and the refactoring doesn't alter any existent logic.

A reason we have to refactor EINT code pieces into a generic way is that
currently, they're tightly coupled with a certain type of MediaTek pinctrl
would cause a grown in a very bad way as there is different types of
pinctrl devices getting to join.

Therefore, it is an essential or urgent thing that EINT code pieces are
refactored to eliminate any dependencies across GPIO and EINT as possible.

Additional structure mtk_eint_[xt, hw, regs] are being introduced for
indicating how maps being designed between GPIO and EINT hw number, how to
set and get GPIO state for a certain EINT pin, what characteristic on a
EINT device is present on various SoCs.

pinctrl: mediatek: add pinctrl driver for MT7622 SoC

2017-12-20T07:49:41+00:00

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.
