Add BCM63xx USBH PHY driver for BMIPS.
Signed-off-by: Álvaro Fernández Rojas <[email protected]>
---
v6: introduce changes suggested by Vinod:
- Remove BMIPS_GENERIC default from kconfig.
- Print registered message as debug.
v5: use devm_reset_control_get_exclusive.
v4: several improvements:
- Use devm_platform_ioremap_resource.
- Code cleanups.
- Improve device mode config:
- Move USBH_SWAP_CONTROL device mode value to variant variable.
- Set USBH_UTMI_CONTROL1 register value (variant variable).
v3: introduce changes suggested by Florian:
- Add support for device mode.
v2: introduce changes suggested by Florian:
- Drop OF dependency (use device_get_match_data).
- Drop __initconst from variant tables.
- Use devm_clk_get_optional.

Hello Simon,
This is based on your work:
https://github.com/nomis/linux/commit/c4c55b603a78e2732044a833e248c1a1087e7053
https://github.com/nomis/linux/commit/f153a58b9e6f88e72c3ef34dc076118f8b3ade5b
You never sent it, but I took it from your Github.
Nevertheless, I can remove you from these patches.
Best regards,
Álvaro.

Ok, it has been a long time and I couldn't find a branch with those in
locally.
Please remove my *email address* from the source code and MODULE_AUTHOR
