Support host selector using cpld definitions
Description:
- Support host selector using cpld definitions
Design:
- Because the current structure only supports config defined by GPIO
(Yosemite V2), but there are also have the system (Yosemite V3.5)
gets the host-selector's selection from CPLD.
- So this commit is to extend the current configuration to use CPLD
definitions. Also, support adding event io from the register file
which was exported from the CLD driver.
- For example with config json below:
{
"cpld_definitions": [
{
"name": "HOST_SELECTOR",
"i2c_address": 15,
"i2c_bus": 12,
"register_name": "uart-selection-debug-card",
"max_position": 4
}
]
}
Dependency:
- CLD driver is required (link: https://lore.kernel.org/lkml/20230117094425.19004-1-Delphine_CC_Chiu@Wiwynn.com/)
Test Case:
- When ocp debug card uart button is pressed the position property on
dbus is correct.
