Subject: [PATCH] mfd/gpio: move HTC GPIO driver to GPIO subsystem
The HTC GPIO driver is a pure GPIO driver and I just can not
see what it is doing inside MFD. Let's just move it to GPIO
and take this opportunity to move the platform data to
<linux/platform_data/gpio-htc-egpio.h>

Cc: Lee Jones <lee.jones@...aro.org>
Signed-off-by: Linus Walleij <linus.walleij@...aro.org>

Lee if you're OK with this I will provide an immutable branch
for you to pull this into MFD as well (or if you prefer to
prep it, be my guest...)
Russell/ARM SoC: heads-up and ACK request.
