[ARM] 2890/1: OMAP 1/4: Update omap1 specific files, take 2
Patch from Tony Lindgren This patch syncs the mainline kernel with linux-omap tree. The highlights of the patch are: - Convert more drivers to register resources in board-*.c to take advantage of the driver model by David Brownell and Ladislav Michl - Use set_irq_type() for GPIO interrupts instead of omap_set_gpio_edge_ctrl() by David Brownell - Add minimal support for handling optional add-on boards, such as OSK Mistral board with LCD and keypad, by David Brownell - Minimal support for loading functions to SRAM by Tony Lindgren - Wake up from serial port by muxing RX lines temporarily into GPIO interrupts by Tony Lindgren - 32KHz sched_clock by Tony Lindgren and Juha Yrjola Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
