Holger Brunck 067bb938da net/wan/fsl_ucc_hdlc: add hdlc-bus support ... This adds support for hdlc-bus mode to the fsl_ucc_hdlc driver. This can be enabled with the "fsl,hdlc-bus" property in the DTS node of the corresponding ucc. This aligns the configuration of the UPSMR and GUMR registers to what is done in our ucc_hdlc driver (that only support hdlc-bus mode) and with the QuickEngine's documentation for hdlc-bus mode. GUMR/SYNL is set to AUTO for the busmode as in this case the CD signal is ignored. The brkpt_support is enabled to set the HBM1 bit in the CMXUCR register to configure an open-drain connected HDLC bus.
