Subject[PATCH v1 2/2] pinctrl: Kconfig/Makefile for building MediaTek pinctrl v2 driver as kernel module
Date
From: Light Hsieh <light.hsieh@mediatek.com>

1. drivers/pinctrl/mediatek/Kconfig:
1.1 PINCTRL_MT6765: change from bool to tristate. It is specified in
defconfig file.
1.2 PINCTRL_MTK_PARIS: change from bool to tristate and select
PINCTRL_MTK_V2. No need to specify in defconfig file.
* PINCTRL_MTK_PARIS will be y if any PINCTRL_MTXXXX selecting
PINCTRL_MTK_PARIS is y.
* PINCTRL_MTK_PARIS will be n if all PINCTRL_MTXXXX selecting
PINCTRL_MTK_PARIS are n.
* PINCTRL_MTK_PARIS will be m if all PINCTRL_MTXXXX selecting
PINCTRL_MTK_PARIS are m.
1.3 PINCTRL_MTK_MOORE: select EINT_MTK and PINCTRL_MTK_V2.
1.4 PINCTRL_MTK_V2: add this tristate config which depends on
PINCTRL_MTK_PARIS and PINCTRL_MTK_MOORE. No need to specify in
defconfig file.
* PINCTRL_MTK_V2 will be y if either PINCTRL_MTK_PARIS or
PINCTRL_MTK_MOORE is y.
* PINCTRL_MTK_V2 will be n if both PINCTRL_MTK_PARIS and
PINCTRL_MTK_MOORE are n.
* PINCTRL_MTK_V2 will be m if both PINCTRL_MTK_PARIS is m and
PINCTRL_MTK_MOORE is n.
1.5 EINT_MTK: change from bool to tristate and add rule for default.
No need to specify in defconfig file.
* First rule: determine if EINT_MTK is y or n according to
selection of PINCTRL_MTK or PINCTRL_MTK_MORE.
* Second rule: determine if EINT_MTK is y, m, or n according to
selection of PINCTRL_MTK_PARIS.

2. drivers/pinctrl/mediatek/Makefile: Use PINCTRL_MTK_V2 to determine
if pinctrl-mtk-common-v2.c is built as kernel module or
built-in.
