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) Cc: stable@vger.kernel.org Signed-off-by: Oliver Graute <oliver.graute@kococonnector.com> Link: https://lore.kernel.org/r/20220210085322.15676-1-oliver.graute@kococonnector.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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
