[v4,0/4] soc: xilinx: vcu: provide interfaces for other drivers

Message

Hello,

this is v4 of the series to expose the vcu-settings via syscon. This is
necessary, because other drivers, e.g. the allegro-dvt driver, need to read
the VCU settings as well.

I dropped the patches that register the clock controller for now. The patch
stack to rework the driver to properly provide the PLL and clock dividers grew
to a level that justifies a separate series.

The individual patches do not contain any changes compared to v3.

Michael

Changelog:

v3 -> v4:
- Drop patches that add a clock controller

v2 -> v3:
- drop unused xvcu_reset() function

v1 -> v2:
- drop custom select for syscon
- unregister registered clocks on driver remove

Michael Tretter (4):
  soc: xilinx: vcu: drop useless success message
  dt-bindings: soc: xlnx: extract xlnx, vcu-settings to separate binding
  soc: xilinx: vcu: use vcu-settings syscon registers
  soc: xilinx: vcu: add missing register NUM_CORE
