-Krait Processor Sub-system (KPSS) Application Clock Controller (ACC)
-
-The KPSS ACC provides clock, power domain, and reset control to a Krait CPU.
-There is one ACC register region per CPU within the KPSS remapped region as
-well as an alias register region that remaps accesses to the ACC associated
-with the CPU accessing the region.
-
-PROPERTIES
-
-- compatible:
- Usage: required
- Value type: <string>
- Definition: should be one of:
- "qcom,kpss-acc-v1"
- "qcom,kpss-acc-v2"
-
-- reg:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: the first element specifies the base address and size of
- the register region. An optional second element specifies
- the base address and size of the alias register region.
-
-- clocks:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: reference to the pll parents.
-
-- clock-names:
- Usage: required
- Value type: <stringlist>
- Definition: must be "pll8_vote", "pxo".
-
-- clock-output-names:
- Usage: optional
- Value type: <string>
- Definition: Name of the output clock. Typically acpuX_aux where X is a
- CPU number starting at 0.
-
-Example:
-
- clock-controller@2088000 {
- compatible = "qcom,kpss-acc-v2";
- reg = <0x02088000 0x1000>,
- <0x02008000 0x1000>;
- clocks = <&gcc PLL8_VOTE>, <&gcc PXO_SRC>;
- clock-names = "pll8_vote", "pxo";
- clock-output-names = "acpu0_aux";
- };

Convert kpss-acc driver Documentation to yaml. The original Documentation was wrong all along. Fix it while we are converting it. The example was wrong as kpss-acc-v2 should only expose the regs but we don't have any driver that expose additional clocks. The kpss-acc driver is only specific to v1. For this exact reason, limit all the additional bindings (clocks, clock-names, clock-output-names and #clock-cells) to v1 and also flag that these bindings should NOT be used for v2.
