To: Linux-MIPS, Ralf Baechle; +Cc: Manuel Lauss
Noone seems to have test hardware or care anymore. Drop PB1000 support
and along with it the old Alchemy PCMCIA socket driver.

Please repost cc'ing the net / irda and pcmcia lists and maintainers. Even
if code is only getting removed there still is a potencial for conflicts
with other patches and generally maintainers' ego prefers a full mailbox :)
Thanks,

Noone seems to have test hardware or care anymore. Drop PB1000 support
and along with it the old Alchemy PCMCIA socket driver.
Cc: netdev@vger.kernel.org
Cc: linux-pcmcia@lists.infradead.org
Signed-off-by: Manuel Lauss <manuel.lauss@googlemail.com>

Resend with CC's added as requested by Ralf.
Cc'ing netdev for IrDA driver parts and pcmcia for the socket driver
removal.

From: Manuel Lauss @ 2011-11-01 19:03 UTC (permalink / raw)
To: Linux-MIPS, Ralf Baechle; +Cc: Manuel Lauss
No test hardware and no (apparent) users. These boards seem very
similar to the DB1500, so if required support can be brought back
again (I have datasheets) but then with dedicated board code, not
tacked on to DB1000 support.
Signed-off-by: Manuel Lauss <manuel.lauss@googlemail.com>

I need these gone for upcoming combined DB1000/1500/1100 support.

Initially I had to write to both the MASK and ENABLE registers,
otherwise the CPLD would generate tons of spurious interrupts.
With the change to the demux handler to disable the muxed line,
it is now sufficient to disable the interrupt by writing either
the enable or mask register.

Add basic support for the Au1300 variant(s):
- New GPIO/Interrupt controller
- DBDMA ids
- USB setup
- MMC support
- enable various PSC drivers
- detection code.

From: Manuel Lauss @ 2011-11-01 19:03 UTC (permalink / raw)
To: Linux-MIPS, Ralf Baechle; +Cc: Manuel Lauss, linux-fbdev
au1200fb calls 3 functions which have to be defined in board code.
Fix this ugliness with the introduction of platform_data.
Cc: linux-fbdev@vger.kernel.org
Signed-off-by: Manuel Lauss <manuel.lauss@googlemail.com>

I'd like this to go in via the MIPS tree since patches depend on it.

@ 2011-11-01 19:03 ` Manuel Lauss

From: Manuel Lauss @ 2011-11-01 19:03 UTC (permalink / raw)
To: Linux-MIPS, Ralf Baechle; +Cc: Manuel Lauss, linux-fbdev
au1200fb calls 3 functions which have to be defined in board code.
Fix this ugliness with the introduction of platform_data.
Cc: linux-fbdev@vger.kernel.org

I'd like this to go in via the MIPS tree since patches depend on it.

The PB1200 is basically a DB1200 with additional MMC and camera sockets
and different base addresses for external hardware (CPLD, IDE, Net, NAND).
This patch implements the missing PB1200 features in DB1200 support code
and runtime board detection.
Tested on DB1200 only.

To: Linux-MIPS, Ralf Baechle; +Cc: Manuel Lauss
These 3 boards are very similar; with this patch a single kernel image
which runs on all three can be built.
Tested on DB1500 and DB1100.

Done, but:
patching file arch/mips/alchemy/devboards/db1000.c
Hunk #1 succeeded at 25 with fuzz 1.
As with every use of symbol_get I wonder if this is not a case of doing
something the very wrong way.

All Devboards can use the 32kHz counter as a RTC device.
Also delete the custom CMOS RTC header, which can be used for the
DS1693 on the PB1500. But since it doesn't have a buffer battery
it is as useful as the on-chip RTC which I prefer.

Transform the au1550nd.c driver into a platform_driver and hook it
up in the PB1550 board (gen_nand works fine on the DB1550, but since
I don't have a PB1550 to test this driver stays for now).

Tested on the DB1550 as well.
I'd like for this to go in via the MIPS tree if at all possible.

To: Linux-MIPS, Ralf Baechle; +Cc: Manuel Lauss, Samuel Ortiz, netdev
Moderate driver cleanup:
convert to platform driver, get rid of board-specific code.
Driver loads and runs on a DB1100 board. But since I have no other
IrDA hardware to exchange data with I can't say whether it really sends
and receives.

I'd like for this to go in via the MIPS tree since other mips patches depend
on it.
