Hello Rui,
Here is a patch set for your consideration on ti-soc-thermal driver.
This patch set is mix of:
(a) patches that were added to the staging tree post 3.10-rc1 but
were not included after the move from staging to thermal. This is
because your thermal tree is based of 3.10-rc1 and not staging/next
or linux-next/master. Thus the first two patches make sure the driver
under drivers/thermal/ti-soc-thermal has also the needed fixes.
(b) patches containing fixes found during the addition of DRA752
chip support.
(c) patches adding the support to DRA752 chips.
Please consider these too for 3.11.
For those people interested in testing this patch set, it is based
on thermal/next and can also be found here:
https://git.gitorious.org/thermal-framework/thermal-framework.git thermal_work/ti-soc-thermal/fixes+dra752
All best,
Eduardo Valentin (7):

This macro can lead to dangerous results, like returning success (0) during a failure scenario (NULL pointer handling). For this reason this patch is changing the driver after revisiting the code. These are the cases: i. For cases in which IS_ERR_OR_NULL() is used for checking return values of functions that returns either PTR_ERR() or a valid pointer, it has been translated to IS_ERR() check only. ii. For cases that a NULL check is still needed, it has been translated to if (!ptr || IS_ERR(ptr)).

* [PATCHv2 5/7] thermal: ti-soc-thermal: add thermal data for DRA752 chips 2013-06-03 20:31 ` Eduardo Valentin @ 2013-06-03 20:33 ` Eduardo Valentin 0 siblings, 0 replies; 16+ messages in thread From: Eduardo Valentin @ 2013-06-03 20:33 UTC (permalink / raw) To: rui.zhang; +Cc: linux-pm, linux-kernel, Eduardo Valentin This patch adds the thermal data for TI DRA752 chips. In this change it includes (autogen): . Register offset definitions . Bitfields and masks for all registers . Conversion table Also, the thermal limits, thresholds and extrapolation rules are included. The extrapolation rule is simply add +2C as margin. All 5 sensors, MPU, GPU, CORE, DSPEVE and IVA, are defined and exposed. Only MPU has cooling device.

And I must also admit my original plan was to use dra7xx naming convention. Not only on DT nodes, but in driver source code symbols too. Well, this is about re-usability, right? However, I took a step back and thought about the bandgap IP history. Take that in mind, just look to the source code. We never succeed to reuse nodes fully and it is because bandgap IPs do change from chip version to chip version. That is also understandable as every chip has its own thermal peculiarities. For instance, we do not have a omap4xxx node because each OMAP4 chip has a different bandgap IP, with different features. I really would like to use a dra7xxx node, but that would contradict the IP history :-). If we are trying to avoid patching the driver in the future, I would say it is more likely to have a patch for another dra7 chip with specifics different from the current one than having a patch reusing the existing dra752 node. This statement is obviously based on driver and IP history (I might be wrong of course and the IP could actually have reached a development stabilization point). + interrupts = <0 126 4>; /* talert */ > > > The TRM does not have any term called talert.

But the TI thermal engineering community have coined this term and I think it is quite common used (within that community) and if you look to the driver code too, it is all over. I believe there is no doubt that talert stands for thermal alert. The driver code does have documentation about that. >> +}; > > > Regards, > Keerthy > > -- You have got to be excited about what you are doing. (L.

Hello Rui,
Here is a patch set for your consideration on ti-soc-thermal driver.
This patch set is mix of:
(a) patches that were added to the staging tree post 3.10-rc1 but
were not included after the move from staging to thermal. This is
because your thermal tree is based of 3.10-rc1 and not staging/next
or linux-next/master. Thus the first two patches make sure the driver
under drivers/thermal/ti-soc-thermal has also the needed fixes.
(b) patches containing fixes found during the addition of DRA752
chip support.
(c) patches adding the support to DRA752 chips.
Please consider these too for 3.11.
For those people interested in testing this patch set, it is based
on thermal/next and can also be found here:
https://git.gitorious.org/thermal-framework/thermal-framework.git thermal_work/ti-soc-thermal/fixes+dra752
All best,
Eduardo Valentin (7):
thermal: ti-soc-thermal: update DT reference for OMAP5430
thermal: ti-soc-thermal: remove external heat while extrapolating
hotspot

thermal: ti-soc-thermal: add thermal data for DRA752 chips
thermal: ti-soc-thermal: add dra752 chip to device table
thermal: ti-soc-thermal: add DT example for DRA752 chip
