backlight: Add TPS65217 WLED driver 2012-09-25T08:42:02+00:00 Matthias Kaehlcke matthias@kaehlcke.net 2012-09-24T20:25:28+00:00 eebfdc17cc6c9f184a713d84b84e7602236360c6 The TPS65217 chip contains a boost converter and current sinks which can be used to drive LEDs for use as backlights. Expose this functionality via the backlight API. Tested on an AM335x based custom board with a single WLED string, using different values for ISEL and FDIM (though it would be hard to tell the difference except for the value in WLEDCTRL1). Both instantiation through the device tree and by passing platform data have been tested. Testing has been done with an Androidized 3.2 kernel from the rowboat project.
