Each LPD880x LED driver chip has some output channels (3 channels for LPD8803, 6 for LPD8806), whose PWM duty cycle can be set at 7 bit resolution via a reduced SPI interface (MOSI and CLK lines only). Each chip also includes data and clock out pins for daisy chaining LED strips. if LPD880X_STRIP config LPD880X_STRIP_NAME string "Driver name" default "lpd880x_strip" help Device name for LPD880x LED strip. config LPD880X_STRIP_SPI_DEV_NAME string "SPI master to use to drive the strip" default "" help Specify the device name of the SPI master which the LPD880X driver should use to control the LED strip. Examples: SPI_0, SPI_1, etc. config LPD880X_STRIP_SPI_BAUD_RATE int "Strip clock line frequency" default 2000000 help SPI clock rate, in Hz, to use while driving the strip. The recommended maximum is 2 MHz (2000000); the absolute maximum is 20 MHz (20000000). If unsure, accept the default value. endif # LPD880X_STRIP
