The Microchip Flexcom is just a wrapper which embeds a SPI controller, an I2C controller and an USART. Only one function can be used at a time and is chosen at boot time according to the device tree. The bindings are kept as in Linux. The driver registers to MISC_UCLASS. Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com>
