From 8bd5741e3145e40c1e4f422fa5f1b9d7fe0644b3 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Thu, 14 May 2020 17:50:37 +0530 Subject: usb: renesas-xhci: Add the renesas xhci driver This add a new driver for renesas xhci which is basically a firmware loader for uPD720201 and uPD720202 w/o ROM. The xhci-pci driver will invoke this driver for loading/unloading on relevant devices. This patch adds a firmware loader for the uPD720201K8-711-BAC-A and uPD720202K8-711-BAA-A variant. Both of these chips are listed in Renesas' R19UH0078EJ0500 Rev.5.00 "User's Manual: Hardware" as devices which need the firmware loader on page 2 in order to work as they "do not support the External ROM". The "Firmware Download Sequence" is describe in chapter "7.1 FW Download Interface" R19UH0078EJ0500 Rev.5.00 page 131. The firmware "K2013080.mem" is available from a USB3.0 Host to PCIe Adapter (PP2U-E card) "Firmware download" archive. An alternative version can be sourced from Netgear's WNDR4700 GPL archives. The release notes of the PP2U-E's "Firmware Download" ver 2.0.1.3 (2012-06-15) state that the firmware is for the following devices: - uPD720201 ES 2.0 sample whose revision ID is 2. - uPD720201 ES 2.1 sample & CS sample & Mass product, ID is 3. - uPD720202 ES 2.0 sample & CS sample & Mass product, ID is 2.
