It deals with three platforms: EyeQ5, EyeQ6L and EyeQ6H. First two have a single instance, whereas EyeQ6H has seven named instances. Features provided are: - Clocks, children to main crystal. Some PLLs and divider clocks. - Resets. EyeQ6H central, south, DDR0 and DDR1 do not have resets. - Pinctrl. Only EyeQ5 has such feature. Those are NOT the only registers exposed in OLB system-controllers! Many individual registers, related to IP block integration, can be found. We simplify devicetree references to OLB in two ways: - Compatibles exposing a single clock do not ask for a index argument. - Compatibles exposing a single reset domain do not ask for a domain index, only a reset index. About pinctrl subnodes: all pins have two functionality, either GPIO or something-else. The latter is pin dependent, we express constraints using many if-then.
