X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=dc4b2068934d6562048393d4531b9983df41b14e;p=openwrt%2Fstaging%2Fblogic.git

staging: fbtft: Add reset to fbtft_init_display_dt()

When an init sequence is present in the Device Tree,
fbtft_init_display_dt() is used to initialize the display.
Add missing reset function call and activation of
chip select for parallel bus.
