* arm: mx31: use common timer functionsAndrew Ruder2014-09-161-0/+10
| | | | | | | | | | | | | | | | | | | | This patch moves mx31 to the common timer functions added in commit 8dfafdd - Introduce common timer functions <Rob Herring> The (removed) mx31 timer code (specifically __udelay()) could deadlock at the 32-bit boundary of get_ticks(). get_ticks() returned a 32-bit value cast up to a 64-bit value. If get_ticks() + tmo in __udelay() crossed the 32-bit boundary, the while condition became unconditionally true and locks the processor. Rather than patch the specific mx31 issues, simply move everything over to the common code.

* mmc: access mxcmmc from mx31 boardsHelmut Raiger2012-02-123-2/+14
| | | | | | | | | | | | | | | | | This patch modifies mxcmmc.c to be used not only by i.MX27 but also by i.MX31 boards. Both use the same SD controller, but have different clock set-ups. The i.MX27 imx_get_XXXclock functions are made static to generic.c and a public mxc_get_clock() function is provided. Pins, base address and prototypes for an i.MX31 specific board_init_mmc() are provided. Some of the i.MX27 clock getters are unused and marked as such to avoid warnings (./MAKEALL -s mx27), but the code was left in for future use.

* IMX: MX31: Cleanup include files and drop nasty #ifdef in driversStefano Babic2011-04-272-3/+3
| | | | | | | | | | 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).

* MX31: add support for MX31 watchdogStefano Babic2011-04-271-0/+10
| | | | | | | | | | | | | | | | | | 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.
