Subject: [PATCH 0/2] USB: host: ehci-atmel: Enable HSIC port on SAMA5D2
Date: Fri, 10 Sep 2021 19:38:40 +0300 [thread overview]
Message-ID: <20210910163842.1596407-1-cristian.birsan@microchip.com> (raw)
From: Cristian Birsan <cristian.birsan@microchip.com>
On SAMA5D2 SoCs, Port C of USB Host contains a High-Speed Inter-Chip (HSIC)
transceiver. It can be used for USB chip-to-chip interconnect with a 2-signal
(strobe, data) synchronous serial interface using 240 MHz DDR signaling.
External cables, connectors, and hot plug & play are not supported.
This patch series enables this feature.
