Hi, I'd like to add support for lcd backlight on/off switching on omap1 ams-delta board. I could potentially use omap1_bl backlight class device driver for this purpose, but it is not fully compatible with ams-delta, as it actually changes lcd contrast instead of backlight intensity on this board. I can see two possible ways of controlling backlight on omap platforms: 1. over omapfb panel device driver, with lcd_panel.set_bklight_level(), 2. over backlight class device driver, using backlight_ops.update_status(). Which method is the preferred one, giving more chances for integration into the mainline kernel?
