Hi,
This is for the most part a repost of the arch/arm/mach-tegra parts of
Erik Gilling's post of the Tegra series from April 13. I've done some
minor cleanups and picked up a couple of bugfixes from later patches,
but I wanted to keep the original series bite size for easier review.
There is more to come once this is in.
Russell, do you prefer to take the initial series and feed it to Linus, or
should I send a direct pull request with your acked-by (once you give it)?
Thanks,
-Olof

From: Olof Johansson @ 2010-06-04 7:10 UTC (permalink / raw)
To: linux-arm-kernel
From: Colin Cross <ccross@android.com>
v2: fixes from Russell King:
- include linux/io.h instead of asm/io.h
- fix whitespace in Kconfig
- Use spin_lock_init to initialize lock
- Return -ENOSYS instead of BUG for unimplemented clock ops
- Use proper return values in tegra2 clock ops
additional changes:
- Rename some clocks to match dev_ids
- add rate propagation
- add debugfs entries
- add support for clock listed in clk_lookup under multiple dev_ids
Merged with separate later patch from Colin:
Don't reset peripherials on clk_disable
Correct flags on dvc_i2c
Remove input clock
Autodetect state of all clocks on init
Add cpu, sys, and bus clocks
Fix clk_set_rate on PLLs
Replace per-clock locking with global clock lock
Olof:
Misc formatting cleanups

v2: fixes from Russell King:
- include linux/io.h instead of asm/io.h
fixes from Gary King:
- remove extra (and incorrect) irq definitions
- use timer 3 instead of timer 1 for compatibility with other drivers
- fix typo that disabled oneshot mode

From: Erik Gilling <konkers@android.com>
v2: fixes from Mike Rapoport:
- move gpio-names.h to arch/arm/mach-tegra
fixes from Russell King
- include linux/io.h and linux/gpio.h instead of asm/io.h
and asm/gpio.h
additional changes:
- add macros to convert between irq and gpio numbers for platform data
- change for_each_bit to for_each_set_bit in gpio.c
Olof:
- Bring in 'mask irq sense type' bugfix

To: linux-arm-kernel
We'll keep tegra_defconfig as the SoC-specific superset defconfig
that will contain relevant options for all supported boards, to avoid
proliferation of board-specific defconfigs.

How did you calculate the magic mult/shift numbers 16777/24 and
1000/0 above? Especially the latter intuitively seem very inappropriate,
and I guess there will be revisions of this platform with new frequencies
for the timer as well, making these hard-coded values a bug source.
I would consider using the
clocksource_calc_mult_shift() and
clockevents_calc_mult_shift()
functions based on the frequency of the timer counter and a minimum wakeup
range if you don't know exactly why you want these mult+shifts.
I posted some patches to encourage the use of these recently.

Ummmm what is this = 216000000/16 * 16?
I think the compiler will optimize that to 216000000 so why not set
it to that.

Yeah, I messed up and accidentally based it on .34 instead of current
-rc at time of posting.
Erik and Colin have rebased properly and folded in the changes from your
other comments. I'll leave it up to them but you should see an email
about it at some point.

Thanks, fixed. The numbers are correct, as Tegra timers all run at
1MHz regardless of input clock frequency, but removing the magic
numbers is clearer.
For the clocksource, I replaced it with clocksource_register_hz, which
hides the minsec number as well. Clockevents I replaced iwth
clockevents_calc_mult_shift.
