[PATCH v3 0/4] dt-bindings: xilinx: Add missing firmware child nodes

[PATCH v3 0/4] dt-bindings: xilinx: Add missing firmware child nodes

[Michal Simek]

Hi,

series is converting missing descriptions for child nodes and also
synchronizing name for power-management discussed with Krzysztof in v1
version available here.
https://lore.kernel.org/r/fc7863a2-d3c5-47c8-9484-ef9cd6d7dd5d@linaro.org

Thanks,
Michal

Changes in v3:
- s/power-controller/power-management/g
- extend example
- s/power-controller/power-management/g
- align commit message
- s/power-controller/power-management/g
- update subject and commit message to match sed above

Changes in v2:
- Sort nodes by name
- Rename zynqmp-power to power-controller
- Keep only single patch for easier handling as done in v1
- New patch in series
- New patch is series
- New patch is series

[PATCH v3 1/4] dt-bindings: firmware: xilinx: Describe missing child nodes

[Michal Simek]

Firmware node has more than fpga, aes and clock child nodes but also power,
reset, gpio, pinctrl and pcap which are not described yet.
All of them have binding in separate files but there is missing connection
to firmware node that's why describe it.

[PATCH v3 2/4] dt-bindings: firmware: xilinx: Sort node names (clock-controller)

[Michal Simek]

Nodes should be sorted that's why move clock-controller to the top of list.
