ARM: OMAP1: create read_reset_sources() function (for initial use by watchdog)
On OMAP1, the existing OMAP watchdog driver reads a register directly from a non-watchdog IP block. It also does not convert the register's contents into the standard WDIOF_* bits expected from the GETBOOTSTATUS ioctl(). To move towards fixing these problems, create an function in arch/arm/mach-omap1 to return the reset source data. A subsequent patch will provide this function to the watchdog driver via platform_data. In the long term, the best approach would be to move this function to a new OMAP1 driver that handles access to the OMAP1 Clock Generation and Reset Management IP block. Then no platform_data would be needed. Signed-off-by: Paul Walmsley <paul@pwsan.com>
