7 title: HDMI CEC GPIO
10 - Hans Verkuil <hverkuil-cisco@xs4all.nl>
13 The HDMI CEC GPIO module supports CEC implementations where the CEC line is
14 hooked up to a pull-up GPIO line and - optionally - the HPD line is hooked up
17 Please note:: the maximum voltage for the CEC line is 3.63V, for the HPD and

26 between 0 and n-1, n being the number of GPIOs managed by the chip.
29 example if a system uses a memory-mapped set of I/O-registers where 32 GPIO
30 lines are handled by one bit per line in a 32-bit register, it makes sense to
44 So for example one platform could use global numbers 32-159 for GPIOs, with a
45 controller defining 128 GPIOs at a "base" of 32 ; while another platform uses
46 global numbers 0..63 with one set of GPIO controllers, 64-79 with another type
47 of GPIO controller, and on one particular board 80-95 with an FPGA. The legacy
