MX31: Disable watchdog during low-power modes

2011-09-30T20:01:00+00:00

Turn on the watchdog WDZST bit so that watchdog timer does not count during low power modes.

Prior to applying this patch mx31pdk board got watchdog resets because when it booted in the Linux prompt
and there was no activity, the system entered into idle mode while watchdog timer was still active.

Fix this by disabling watchdog timer during idle mode.

Timer: Remove reset_timer_masked()

2011-07-26T12:54:15+00:00

In some circumstances, reset_timer_masked() was called be timer_init() in
order to perform architecture specific timer initialisation. In such
cases, the required code in reset_timer_masked() has been moved into
timer_init()

Timer: Remove reset_timer() for non-Nios2 arches

Timer: Remove set_timer completely

IMX: MX31: Cleanup include files and drop nasty #ifdef in drivers

2011-04-27T17:38:05+00:00

As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

MX31: add support for MX31 watchdog

2011-04-27T17:38:04+00:00

The patch add CONFIG_HW_WATCHDOG to be used
with the internal watchdog timer of the MX31
processor. Two function are exported for the
board maintainers:
	mxc_hw_watchdog_enable
	mxc_hw_watchdog_reset

The board maintainer can decide to use mxc_hw_watchdog_reset as
hw_watchdog_reset, or to implement his own function to reset
the watchdog.
The watchdog timer can be configured with CONFIG_SYS_WD_TIMER_SECS
(value in seconds). The MX31 allows values between 0.5
(CONFIG_SYS_WD_TIMER_SECS = 0) and 128 seconds.
