From: Umang Chheda Date: Tue, 3 Mar 2026 16:43:14 +0000 (+0530) Subject: arm64: dts: qcom: monaco-evk: Add IFP Mezzanine X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5a67924d2fc5787d894bdbd8a87ad6794487060d;p=thirdparty%2Fkernel%2Fstable.git arm64: dts: qcom: monaco-evk: Add IFP Mezzanine 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 - PCIe Monish Chunara - EEPROM.
