Written a tps6507x charger driver, now where do I post it?

Mike Looijmans

I've built a power supply class driver for the battery charger of the tps6507x, much like the twl4030_charger driver, which extends the tps6507x platform driver with AC/USB supply detection, battery charging detection and a few things more. For example, one can make a LED switch on when inserting an AC adapter.

Since the driver is very generic and can apply to all boards with this power management chip, I want to push it upstream.

How do I do that? Where do I send it?

I'll have no problem creating GIT patches based on whatever kernel version you'd like in the range 2.6.37 and up.

Mike, where did this land? Thanks.

Since no one seemed to care for months, It never "landed" anywhere. The project it related to has ended (read: no more funding).

I'll be happy to send/post the "raw" code, if anyone wants it, since it's GPL licensed anyway.

Well that explains why I could not find it.... Yes if you could post the code that would be very helpful.

Here's the "raw" code:

7750.tps6507x.tar.gz

To make it useful for you, make the following changes:

- The IRQ on the OMAP SOM from LogicPD is GPIO2[3] instead of 3[8]. Best make this a board config (or devicetree, if you feel like it) item.

- You can remove the hack that adds support for a charger detection chip (MAX14578AE)

- Add Makefile and Kconfig entries for the tps6507x-charger.c file

- There may be a conflict between the ADC in the charger driver and the touchscreen driver. Note that the touchscreen does not use the IRQ. A good fix would be to adapt the TS driver and use the same ADC routines for both, and have the touchscreen also use the IRQ to save drastically on CPU usage and I2C traffic.
