Currently most ads7846 config definitions for OMAP3 series boards have been moved to common-board-devices.c, and it is transparent for init. And it's no very proper to do gpio_request based on get_pendown_state since omap_ads7846_init knows everything about ads7846_config. So it's more fit to request gpio according to the right gpio_pendown and set debounce time conditionally. If we don't set proper debouce time, there are flooded interrupt counters of ads7846 responding to one time touch on screen, then the driver couldn't work very well. This patch has been validated on 3530evm. Signed-off-by: Zumeng Chen <zumeng.chen@windriver.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
