* Add support for TI TLC59208F The chip is a 8-BIT FM+ I2C BUS LED DRIVER with 8 open-drain output channels. Its features include: - 256 linear levels - group dimming - group blinking - 64 slave addresses - customizable sub addresses and all call address - output update on stop or on ACK - 3.3V or 5V supply with 5V tolerant IO - no glitch startup - 50mA / output continuous current up to 17V * Convert macro to uint8_t Variables had to be renamed, clang-format would protest against mixed case in global variable name. * Change gen-call reset to use the correct i2c bus
