Subject: [PATCH v3 0/2] usb: xhci: Load Raspberry Pi 4 VL805's firmware
Date: Tue, 5 May 2020 18:26:05 +0200 [thread overview]
Message-ID: <20200505162607.334-1-nsaenzjulienne@suse.de> (raw)
Newer revisions of the RPi4 need their xHCI chip, VL805, firmware to be
loaded explicitly. Earlier versions didn't need that as they where using
an EEPROM for that purpose. This series takes care of setting up the
relevant infrastructure and run the firmware loading routine at the
right moment.
Note that this builds on top of Sylwester Nawrocki's "USB host support
for Raspberry Pi 4 board" series.
---
Note: this was tested on both rpi_arm64_defconfig on both rpi3 & rpi4.
Changes since v2:
- Correct comment on patch #1
- Address Matthias' comments
Changes since v1:
- Rename function
- Use callback in xhci-pci.c
