Subject: [PATCH v7 0/4] Add peripherals for J784S4

This series adds support for:
- SERDES, WIZ DT nodes, Serdes lane control mux
- DSS and DisplayPort-0 nodes

This support DEPENDS upon another series which was introduced as part
of discussion in v5. That series[1] moves the ti-serdes headers file
from bindings to "arch/arm64/boot/dts/ti". (That series is merged in
linux-next tree)

Changelog v6->v7:
- change compatible for scm_conf to 'simple-bus'
- drop main_cpsw node due to driver dependency on [2]

Changelog v5->v6:
- Change header file according to [1].
- Add idle-state property in serdes_ln_ctrl node.
- Fix dtbs_check warning due to clock-frequency property in serdes_refclk
  node by disabling the node in main.dtsi and enabling it in board file
  when the clock-frequency node is actually added.

Changelog v4->v5:
- rebased the patches on linux-next tip.

Changelog v3->v4:
- add reg property to serdes_ln_ctrl and fix the node name again to
  get rid of dtbs_check error.
- reorder reg, reg-names and ranges property for main_cpsw1.
- correct the order for clocks in serdes_wiz nodes to fix dtbs_check
  warnings.
- fix indentation in reg, reg-names and clock property for dss node.
- add comments for the reg type in dss registers.

Changelog v3->v2:
- fix dtc warnings for 'scm_conf' and 'serdes_ln_ctrl' nodes
  (Checked all the changes of the series with W=12 option during build)
- added clock-frequency for serdes_refclk along with other EVM changes
  This refclk is being used by all the instances of serdes_wiz which
  are disabled by default. So configuring refclk when the serdes nodes
  are used for the first time is okay.

Changelog v1->v2:
- Moved J784S4 EVM changes together to the last patch
  (Suggested by Andrew)
