Subject: [PATCH 23/24 v2] MIPS: Alchemy: use the OHCI platform driver
Convert the Alchemy platform to register the ohci-platform driver, now that
the ohci-platform driver properly handles the specific ohci-au1xxx resume
from suspend case.
This also greatly simplifies the power_{on,off} callbacks and make them
work on platform device id instead of checking the OHCI controller base
address like what was done in ohci-au1xxx.c.
Impacted defconfigs are also updated accordingly to select the OHCI platform
driver.
Signed-off-by: Florian Fainelli <florian@...nwrt.org>
---
Changes since v1:
- updated defconfigs accordingly
- really instantiate "ohci-platform" instead of "ohci-au1xxx"
- rebased on top of the latest OHCI HCD changes
