*	pinctrl: mediatek: Add Pinctrl/GPIO/EINT driver for mt2701	Biao Huang	2016-01-28	1	-1/+11
\| \| \| \| \| \| \| \| \| \|	Add mt2701 support using mediatek common pinctrl driver. MT2701 have some special pins need an extra setting register than other ICs, so adding this support to common code.

*	pinctrl: mediatek: Fix multiple registration issue.	Hongzhou Yang	2015-08-26	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Since our common driver need support main chip and PMU at the same time, that means it will register two pinctrl device, and the pinctrl_desc structure should be used two times. But pinctrl_desc use global static definition, then the latest registered pinctrl device will overwrite the old one's, all members in pinctrl_desc will set to the new one's, such as name, pins and pins numbers, etc. This is a bug. Move pinctrl_desc into mtk_pinctrl, assign new value for each pinctrl device to fix it.

*	pinctrl: mediatek: Add Pinctrl/GPIO driver for mt6397.	Hongzhou Yang	2015-05-19	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

*	pinctrl: mediatek: add ies/smt control to common code.	Hongzhou Yang	2015-05-19	1	-1/+30
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Input enable and smt setting have different register, modify code to fix it. Several mediatek soc use similar input enable/smt setting procedure as mt8173, some soc use generic input enable/smt setting, some soc has no input enable/smt setting. Adding common code to handle all those cases, so future soc driver can use it. Signed-off-by: Hongzhou Yang <hongzhou.yang@mediatek.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

\| \| \| \| \| \| \| \| \| \| \|	Several mediatek soc use similar pull setting procedure as mt8173, the pupd enable and resistance setting are in the same register. Add common code mtk_pctrl_spec_pull_set_samereg out of spec_pull_set in mt8173 to handle this case, so future soc driver can use it.

*	pinctrl: mediatek: data struct optimize and remove unused member	Yingjoe Chen	2015-05-19	1	-8/+2
\| \| \| \| \| \| \| \| \| \| \| \| \|	struct mtk_desc_pin.chip, mtk_pinctrl_devdata.invser_offset and mtk_pinctrl_devdata.chip_type are never used in code. Remove them. Some per-pin data are using int for pin number and offsets. Change to short and rearrange to reduce const data size.

*	pinctrl: mediatek: emulate GPIO interrupt on both-edges	Yingjoe Chen	2015-03-18	1	-0/+4
\| \| \| \| \| \| \| \| \| \| \| \|	MTK EINT does not support generating interrupt on both edges. Emulate this by changing edge polarity while enable irq, set types and interrupt handling. This follows an example of drivers/gpio/gpio-mxc.c.

	The mediatek SoCs have GPIO controller that handle both the muxing and GPIOs. The GPIO controller have pinmux, pull enable, pull select, direction and output high/low control. This driver include common driver and mt8135 part. The common driver include the pinctrl driver and GPIO driver. The mt8135 part contain its special device data.
