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>

* Modified from board-innovator1510.c
|
|
*
|
|
* Code for generic OMAP board. Should work on many OMAP systems where
|
|
* the device drivers take care of all the necessary hardware initialization.
|
|
* Do not put any board specific code to this file; create a new machine
|
|
* type if you need custom low-level initializations.
