Subject: board/BuR/common: support timer5 for pwm-backlight
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9b63ba37274317520bd8752607476dbcce0f8213;p=u-boot.git

board/BuR/common: support timer5 for pwm-backlight

in future we support yet another b&r am335x based board, where Timer 5 is
wired to backlight-driver.

So we introduce a new driver-type '2' to setup timer5 instead timer6.
