#1298522 — [PATCH v3 0/5] pinctrl: mediatek: add pinctrl/GPIO/EINT driver for mt2701

Change in v3:
1. convert to arch_initcall.
2. set direction to input when do input-enable/disable and input-schmitt-enable/disable properties.

Change in v2:
1. add special pinmux setting for some pins.
2. fix mt2701 direction control issue.
3. resort dt-bindings.

#1298524 — [PATCH v3 1/5] ARM: mediatek: Add MT2701 config options for mediatek SoCs.

From: Erin Lo <erin.lo@mediatek.com>

The upcoming MTK pinctrl driver have a big pin table for each SoC
and we don't want to bloat the kernel binary if we don't need it.
Add config options so we can build for one SoC only. Add MT2701.

No I prefer anything in arch/arm/boot/dts/* to go in through
the ARM SoC tree.

It can usually be merged orthogonally anyways.

I take Documenation/devicetree/bindings/* and patches
to the driver itself in drivers/pinctrl/*

Yours,
Linus Walleij

As discussed in
http://lists.infradead.org/pipermail/linux-mediatek/2015-December/003350.html
we should use subsys_initcall() instead.

This change is not directly related to adding mt2710 support and change
behavior for all MTK pinctrl drivers, please create a separate patch for
this.
