A Dcec-ioc-adap-g-phys-addr.rst15 CEC_ADAP_G_PHYS_ADDR, CEC_ADAP_S_PHYS_ADDR - Get or set the physical address
40 To query the current physical address applications call
42 driver stores the physical address.
44 To set a new physical address applications store the physical address in
52 To clear an existing physical address use ``CEC_PHYS_ADDR_INVALID``.
63 The physical address is a 16-bit number where each group of 4 bits
64 represent a digit of the physical address a.b.c.d where the most
69 is supported. The physical address a device shall use is stored in the
73 different physical address of the form a.0.0.0 that the sources will
74 read out and use as their physical address.
