| Series | LED: Add basic LP5860 LED matrix driver | expand |
Hi! > The lp5860 is a LED matrix driver with 18 constant current sinks and 11 > scan switches which allows controlling up to 198 LED dots. 200 points. Is it likely to be used as individual LEDs? > Documentation/ABI/testing/sysfs-class-spi-lp5860 | 73 ++++ I'm not big fan of new ABI. Should currents / per channel dimming be configured from dts (and not sysfs)? Best regards, Pavel
The lp5860 is a LED matrix driver with 18 constant current sinks and 11 scan switches which allows controlling up to 198 LED dots. This series adds just the basic support for the device on the SPI bus. It is also possible to use it on I2C. The interface can be switched/selected via an interface select pin.
