2007-04-27[AVR32] Don't enable clocks with no usersHaavard Skinnemoen
Bring the code that sets the initial PM clock masks in line with the comment preceding it by only enabling clocks that have users != 0. Fix SM clock definition and avr32_hpt_init() so that the SM and TC0 clocks keep ticking. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-27[AVR32] Change system timer from count-compare to Timer/Counter 0Hans-Christian Egtvedt
Due to limitation of the count-compare system timer (not able to count when CPU is in sleep), the system timer had to be changed to use a peripheral timer/counter. The old COUNT-COMPARE code is still present in time.c as weak functions. The new timer is added to the architecture directory. This patch sets up TC0 as system timer The new timer has been tested on AT32AP7000/ATSTK1000 at 100 Hz, 250 Hz, 300 Hz and 1000 Hz. For more details about the timer/counter see the datasheet for AT32AP700x available at http://www.atmel.com/dyn/products/product_card.asp?part_id=3903 Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
