Subject: [PATCH 0/4] amlogic: vim3: add support for dynamic PCIe enable
Date: Fri, 18 Sep 2020 11:28:58 +0200 [thread overview]
Message-ID: <20200918092902.28028-1-narmstrong@baylibre.com> (raw)
The VIM3 on-board MCU can mux the PCIe/USB3.0 shared differential
lines using a FUSB340TMX USB 3.1 SuperSpeed Data Switch between
an USB3.0 Type A connector and a M.2 Key M slot.
The PHY driving these differential lines is shared between
the USB3.0 controller and the PCIe Controller, thus only
a single controller can use it.
This serie adds a VIM3 specific board support and adds this dynamic
switching right before booting Linux.
