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] [1] https://lore.kernel.org/lkml/20260210103821.4169-1-umang.chheda@oss.qualcomm.com/ [2] https://lore.kernel.org/lkml/20260222173545.3627478-1-umang.chheda@oss.qualcomm.com/ Umang Chheda (1): arm64: dts: qcom: monaco-evk: Add IFP Mezzanine arch/arm64/boot/dts/qcom/Makefile | 4 + .../dts/qcom/monaco-evk-ifp-mezzanine.dtso | 149 ++++++++++++++++++ 2 files changed, 153 insertions(+) create mode 100644 arch/arm64/boot/dts/qcom/monaco-evk-ifp-mezzanine.dtso -- 2.34.1
