2015-06-02pinctrl: mediatek: Fix bug of ies/smt setting for mt8173.Hongzhou Yang
Add ies/smt support for MSDC3. Also fix ies bug for pin 106 and 107. Signed-off-by: Hongzhou Yang <hongzhou.yang@mediatek.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2015-05-20pinctrl: mediatek: add OF dependency to MT6397Linus Walleij
X86_64 allmodconfig screams like so: warning: (PINCTRL_MT6397) selects PINCTRL_MTK_COMMON which has unmet direct dependencies (PINCTRL && (ARCH_MEDIATEK || COMPILE_TEST) && OF) So add OF to dependencies to shut up this warning.

2015-05-19pinctrl: mediatek: add pinctrl/GPIO/EINT driver for mt8127Yingjoe Chen
MT8127 pinctrl/eint are similar to mt8135 and mt8173, add support for mt8127 using mediatek common pinctrl driver. Signed-off-by: Yingjoe Chen <yingjoe.chen@mediatek.com> Signed-off-by: Hongzhou Yang <hongzhou.yang@mediatek.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2015-05-19pinctrl: mediatek: Add Pinctrl/GPIO driver for mt6397.Hongzhou Yang
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.

2015-05-19pinctrl: mediatek: add ies/smt control to common code.Hongzhou Yang
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>
2015-05-19pinctrl: mediatek: add mtk_pctrl_spec_pull_set_samereg common codeYingjoe Chen
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.

2015-05-19pinctrl: mediatek: data struct optimize and remove unused memberYingjoe Chen
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.

cppcheck detected an uninitialized variable: [drivers/pinctrl/mediatek/pinctrl-mtk-common.c:897]: (error) Uninitialized variable: unmask unmask should be initialized to zero to ensure unmasking only occurs if a previous mask occurred. The current situation is that the unmask variable could contain any random garbage causing random unexpected unmasking.
