[PATCH] I2C: add i2c driver for TPS6501x
This adds an I2C driver for the TPS6501x series of power management chips. It's used on many OMAP based boards, and this driver has been widely used in the Linux-OMAP trees over the last year or so.

If you say yes here you get support for the TPS6501x series of
|
||||
Power Management chips. These include voltage regulators,
|
||||
lithium ion/polymer battery charging, and other features that
|
||||
are often used in portable devices like cell phones and cameras.
|

|

This driver can also be built as a module. If so, the module

will be called tps65010.
