[PATCH 03/32 v4] MIPS: Loongson 1B: use ehci-platform instead of ehci-ls1x.

[PATCH 03/32 v4] MIPS: Loongson 1B: use ehci-platform instead of ehci-ls1x.

[Florian Fainelli]

The Loongson 1B EHCI driver does nothing more than what the EHCI platform
driver already does, so use the generic implementation.

[PATCH 08/32 v4] MIPS: Alchemy: use the ehci platform driver

[Florian Fainelli]

Use the ehci platform driver power_{on,suspend,off} callbacks to perform the
USB block gate enabling/disabling as what the ehci-au1xxx.c driver does.
Update the db1200 and db1300 defconfigs to now select the EHCI platform
driver.

[PATCH 24/32 v4] MIPS: Alchemy: use the OHCI platform driver

[Florian Fainelli]

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.

[PATCH 26/32 v2] USB: move common alchemy USB routines to arch/mips/alchemy/common.c

[Florian Fainelli]

A previous patch converted the Alchemy platform to use the OHCI and EHCI
platform drivers. As a result, all the common logic to handle USB present in
drivers/usb/host/alchemy-common.c has no reason to remain here, so we move it
to arch/mips/alchemy/common/usb.c which is a more appropriate place. This
change was suggested by Manuel Lauss.

Do we need to initilaize static data to 0?

These two defconfig files are no longer in Linus's tree, so I'll just
remove them from this patch.  If that's not ok, can you send a follow-on
patch that adds the config option to the correct defconfig file?

Same issue with the defconfigs in this patch, they aren't around
anymore, so I've removed them from this patch.  If they just moved,
please send a follow-up patch to fix them up.

Indeed, my bad I will follow up with some fixes for this patchset anyway.

Looks like I hit reply too quickly, the patch entitled
"USB: EHCI: remove Loongson 1B EHCI driver" actually removes this bit from
ehci-hcd.c.
