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.
[vkoul: fixed comments:
used macros for timeout count and delay
removed renesas_fw_alive_check
cleaned renesas_fw_callback
removed recursion for renesas_fw_download
add register defines and field names
move to a separate file
make fw loader as sync probe so that we execute in probe and
prevent race
make xhci-pci-renesas a seprate module]
