[PATCH v3 0/1] Introduce Monaco EVK Interface Plus Mezzanine

[PATCH v3 0/1] Introduce Monaco EVK Interface Plus Mezzanine

[Umang Chheda]

Introduce device tree support for the Interface Plus [IFP] Mezzanine
expansion card used with the Qualcomm Monaco Evaluation Kit (EVK).

The Monaco IFP Mezzanine is an additional add-on card which can be
stacked on top of monaco-evk board to extend peripheral capabilities of
monaco-evk used for industrial applications.

It connects via expansion headers on the monaco-evk and provides
following peripherals :
- 4x Type A USB ports in host mode.
- TC9563 PCIe switch, which has following three downstream ports (DSP) :
   - 1st DSP is routed to M.2 E-key connector, intended for WLAN endpoints.
   - 2nd DSP is routed to M.2 B-key connector, intended for cellular modems.
   - 3rd DSP with support for Dual Ethernet ports.
- EEPROM.
- LVDS Display.
- 2*mini DP.

Changelog

v3:
- Add fixed-regulators to satisfy what is required by the bindings
  instead of representing the complete tree which is present on the
  board - Krzysztof.
- Rename fixed-regulator node names as per current format
  recommendation: 'regulator-[0-9]v[0-9]' - Krzysztof.
- Add comment on why output-high property is required for tc9573 pinctrl
  node - Dmitry.
- Update commit text to communicate USB-Hub, LVDS display and mini DP
  support will be added later once the dependent changes are
  available - Dmitry.
- v3-link: [2]

v2:
- Change the DT filename to "monaco-evk-ifp-mezzanine.dtso", also
  update commit text and cover letter text to reflect this change -
Konrad.
- Remove "status=okay" property from i2c15 node - Bjorn.
- Remove "power-source", "input-disable" and "output-enable" properties
  from tc9563_resx_n node and add "output-high" property instead to
  align with TLMM supported bindings - Bjorn.
- Remove extra '\n' from tc9563_resx_n node - Konrad.
- v1-link: [1]

[PATCH v3 1/1] arm64: dts: qcom: monaco-evk: Add IFP Mezzanine

[Umang Chheda]

The IFP Mezzanine is an hardware expansion add-on board designed
to be stacked on top of Monaco EVK.

It has following peripherals :
- 4x Type A USB ports in host mode.
- TC9563 PCIe switch, which has following three downstream ports (DSP) :
   - 1st DSP is routed to an M.2 E-Key connector, intended for
     WLAN modules.
   - 2nd DSP is routed to an M.2 B-key connector, intended for
     cellular modems.
   - 3rd DSP with support for Dual Ethernet ports.
- EEPROM.
- LVDS Display.
- 2*mini DP.

Add support for following peripherals :
- TC9563 PCIe Switch.
- EEPROM.

Enable support for USB hub, LVDS display and mini-DP later once dependent
changes are available in monaco-evk core-kit.

Written with inputs from :
    Krishna Chaitanya Chundru <krishna.chundru@oss.qualcomm.com> - PCIe
    Monish Chunara <monish.chunara@oss.qualcomm.com> - EEPROM.
