Oliver Graute bde6a6b111 staging: fbtft: fb_st7789v: reset display before initialization 
commit b6821b0d9b56386d2bf14806f90ec401468c799f upstream.

In rare cases the display is flipped or mirrored. This was observed more
often in a low temperature environment. A clean reset on init_display()
should help to get registers in a sane state.

Fixes: ef8f317795da (staging: fbtft: use init function instead of init sequence)

  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
