* avr32: Fix cpufreq oops when ondemand governor is defaultHaavard Skinnemoen2008-05-27
| | | | | | | | Move the AP7 cpufreq init to late_initcall() so that we don't try to bring up cpufreq until the governor is ready. x86 also uses late_initcall() for this. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* avr32: Implement set_rate(), set_parent() and mode() for pll1Hans-Christian Egtvedt2008-04-19
| | | | | | | | | | | | | | This patch is a take two of adding full functionality to PLL1 on AT32AP7000. This allows board-specific code and drivers to configure and enable PLL1. This is useful when precise control over the frequency of e.g. a genclock is needed and requested by users for the ABDAC device. The patch is based upon previous patches from both Haavard Skinnemoen and David Brownell.

* avr32: Generic clockevents supportDavid Brownell2008-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This combines three patches from David Brownell: * avr32: tclib support * avr32: simplify clocksources * avr32: Turn count/compare into a oneshot clockevent device Register both TC blocks (instead of just the first one) so that the AT32/AT91 tclib code will pick them up (instead of just the avr32-only PIT-style clocksource). Rename the first one and its resources appropriately. More cleanups to the cycle counter clocksource code - Disable all the weak symbol magic; remove the AVR32-only TCB-based clocksource code (source and header). - Mark the __init code properly. - Don't forget to report IRQF_TIMER. - Make the system work properly with this clocksource, by preventing use of the CPU "idle" sleep state in the idle loop when it's used. Package the avr32 count/compare timekeeping support as a oneshot clockevent device, so it supports NO_HZ and high res timers. This means it also supports plugging in other clockevent devices and clocksources.

* avr32: pass i2c board info through at32_add_device_twiBen Nizette2008-04-19
| | | | | | | | | | | | | | New-style I2C drivers require that motherboard-mounted I2C devices are registered with the I2C core, typically at arch_initcall time. This can be done nice and neat by passing the struct i2c_board_info[] through at32_add_device_twi just like we do for the SPI board info. While we've got the hood up, remove a duplicate declaration of at32_add_device_twi() in board.h.

* gpiolib: avr32 at32ap platform supportDavid Brownell2008-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach AVR32 to use the "GPIO Library" when exposing its GPIOs, so that signals on external chips (like GPIO expanders) can easily be used. This mostly reorganizes some existing logic, with two minor changes in behavior: - The PSR registers are used instead of the previous "gpio_mask" values, matching AT91 behavior and removing some duplication between that role and that of "pinmux_mask". - NR_IRQs grew to acommodate a bank of external GPIOs. Eventually this number should probably become a board-specific config option. There's a debugfs dump of status for the built-in GPIOs, showing which pins have deglitching, pullups, or open drain drive enabled, as well as the ID string used when requesting each IRQ.

* [AVR32] extint: Set initial irq type to low levelHaavard Skinnemoen2008-01-25

Separate out most of the at32_add_device_ide() code and use it to implement at32_add_device_cf() as well.

* [AVR32] CPU frequency scaling for AT32APHans-Christian Egtvedt2007-07-18
| | | | | | | | | | | | | | | | | | | | This patch enables CPU frequency scaling for AT32AP devices. This will enable the CPU to scale between the speed of the high speed bus and the master clock and thus save some power. The patch also adds a parent to cpu_clk and a cpu_clk_set_rate to enable changing the CPU clock divider in a sane way. The driver does not check if the given rate is 0, thus resulting in a div by 0. I think this check should be go into the clk_set_rate framework, and not here. Tested on AT32AP7000/ATSTK1000. Hardware documentation can be found in the AT32AP7000 datasheet.

Only one bus width at a time supported for now.) * Rewrite iowriteN and friends to use write[bwl] and friends (not the __raw counterparts.)

* [PATCH] gpio_direction_output() needs an initial valueDavid Brownell2007-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | It's been pointed out that output GPIOs should have an initial value, to avoid signal glitching ... among other things, it can be some time before a driver is ready. This patch corrects that oversight, fixing - documentation - platforms supporting the GPIO interface - users of that call (just one for now, others are pending) There's only one user of this call for now since most platforms are still using non-generic GPIO setup code, which in most cases already couples the initial value with its "set output mode" request. Note that most platforms are clear about the hardware letting the output value be set before the pin direction is changed, but the s3c241x docs are vague on that topic ... so those chips might not avoid the glitches.
