Hi Greg,
I am sending extra patches on omap-thermal driver, under staging.
There are couple of fixes based on Dan Carpenter's review on
the last patch set I sent. On top of these, there are some
changes on the naming convention for this driver. This rename
is based on previous review cycles that this driver has got.
Besides, it must support other chip families, apart from OMAP,
that's mainly why there is a big rename on this patch set.
And as usual, there are couple of extra fixes.
All these are based on your staging/staging-next branch.
For those interested in testing and trying the driver, these patches are
also available, as usual, here:
git@gitorious.org:thermal-framework/thermal-framework.git thermal_work/omap/ti-thermal-rename

Even if the IRQ is not firing because it is ONE_SHOT and disable
at INTC level, the IRQ handler must use spin_lock_irqsave.
It is necessary to disable IRQs from the current
CPU while it is holding a spin_lock which is need.

* [PATCH 4/8] staging: rename omap-thermal driver to ti-soc-thermal

Cc: devel, linux-omap, linux-kernel, linux-pm, Eduardo Valentin,
Santosh Shilimkar, Benoit, Nishanth Menon
Because this driver will support also OMAP derivatives,
this patch does a big rename inside this driver, so it
better fits its usage.

* [PATCH 4/8] staging: rename omap-thermal driver to ti-soc-thermal
@ 2013-03-18 14:59 ` Eduardo Valentin

Cc: devel, linux-omap, linux-kernel, linux-pm, Eduardo Valentin,
Santosh Shilimkar, Benoit, Nishanth Menon
Because this driver will support also OMAP derivatives,
this patch does a big rename inside this driver, so it
better fits its usage.

Move _ti_bandgap_write_threshold and _ti_bandgap_read_threshold to static
area, as they are local functions.

* [PATCH 6/8] staging: ti-soc-thermal: split writable data from readonly data

This patch changes the data structures of this driver so
that readonly data can reside only in the conf pointer.
Now each register has a struct to hold its configuration info,
to be used base on chip version for instance, and a
struct of values to be written, like register shadow and priv data.

* [PATCH 6/8] staging: ti-soc-thermal: split writable data from readonly data
@ 2013-03-18 14:59 ` Eduardo Valentin

This patch changes the data structures of this driver so
that readonly data can reside only in the conf pointer.
Now each register has a struct to hold its configuration info,
to be used base on chip version for instance, and a
struct of values to be written, like register shadow and priv data.

Gar... I think I was just totally wrong on this. I think your
original code was fine. Sorry Eduardo and Greg.
This is a threaded IRQ so the regular spin_lock is fine or even the
mutex would have been.
IRQ_ONESHOT is about triggering a second IRQ before the first one
has been finished, btw.
I am an idiot.

It would be better to do a minimal move patch which just renames the
files and updated the Makefile. The following patches would rename
the functions. That makes it easier to review.

Put a --- line here after the Signed-off-by line so that "git am"
doesn't include the diff stat in the changelog.

In fact it is. But I rather prefer to use spinlocks there, just to keep
the irq handler sane, even if it is moved to non-threaded IRQ.

It is, and that gets done by masking the IRQ at INTC level.

Not really. Thanks for your time reviewing the driver.
I will resend this series. Drop this one and split patch 4/8 into two
I think (one for moving files, one for renaming functions)
