Typically gpiod_set_value calls would assert the reset line and
then release it using the symantics of:
gpiod_set_value(par->gpio.reset, 0);
... delay
gpiod_set_value(par->gpio.reset, 1);
And the gpio binding would specify the polarity.
Prior to conversion to gpiod calls the polarity in the DT
was ignored and assumed to be active low. Fix it so that
DT polarity is respected.

FBTFT
=========
Linux Framebuffer drivers for small TFT LCD display modules.
The module 'fbtft' makes writing drivers for some of these displays very easy.
Development is done on a Raspberry Pi running the Raspbian "wheezy" distribution.
INSTALLATION
Download kernel sources
From Linux 3.15
cd drivers/video/fbdev/fbtft
git clone https://github.com/notro/fbtft.git
Add to drivers/video/fbdev/Kconfig: source "drivers/video/fbdev/fbtft/Kconfig"
Add to drivers/video/fbdev/Makefile: obj-y += fbtft/
Before Linux 3.15
cd drivers/video
git clone https://github.com/notro/fbtft.git
Add to drivers/video/Kconfig: source "drivers/video/fbtft/Kconfig"
Add to drivers/video/Makefile: obj-y += fbtft/
Enable driver(s) in menuconfig and build the kernel
