[This is a resend of previous patches grouped together]

Misc. updates to various Alchemy parts:
#1: remove hardcoded MAC DMA base from the driver and pass it via
    platform resource information instead.
#2: include the Au1100 in au1000 suspend code
#3: centralize USB block control, to simplify the glues and as a
    preparatory step for Au1300 USB support
#4: do usb setup based on runtime cpu type detection, to get rid of
    a few per-subtype #defines.
#5: with USB out of the way, the rest of the per-subtype peripheral
    base addresses can be removed in favour of a single list.

All run-tested (except 1 and 2 due to lack of hardware) on
DB1200 and DB1300.
Please consider for 3.1.

Manuel Lauss (5):
  net: au1000_eth: pass MACDMA address through platform resource info.
  MIPS: Alchemy: include Au1100 in PM code.
  MIPS: Alchemy: abstract USB block control register access
  MIPS: Alchemy: rewrite USB platform setup.
  MIPS: Alchemy: more base address cleanup

This patch removes the last hardcoded base address from the au1000_eth
driver.  The base address of the MACDMA unit was derived from the
platform device id; if someone registered the MACs in inverse order
both would not work.
So instead pass the base address of the DMA unit to the driver with
the other platform resource information.

The current code forgets the Au1100 when looking for the
correct method to suspend the chip.

Au1200 and Au1300 have one or more registers which control access
to the usb blocks as well as PHY configuration.  I don't want
the OHCI/EHCI glues to know about the different registers and bits,
a new file hides the gory details of USB configuration from them.

  2011-07-08  9:18 ` [PATCH 5/5] MIPS: Alchemy: more base address cleanup Manuel Lauss
  4 siblings, 0 replies; 6+ messages in thread
From: Manuel Lauss @ 2011-07-08  9:18 UTC (permalink / raw)
  To: Linux-MIPS, Ralf Baechle; +Cc: Manuel Lauss

Use runtime CPU detection to setup all USB parts.
Remove the Au1200 OTG and UDC platform devices since there are no
drivers for them anyway.
Clean up the USB address mess in the au1000 header.
