New TiPB - PCMCIA settings

New TiPB - PCMCIA settings

[George Staikos]

   After fighting for a short while, I have some settings for config.opts on
the new Ti PowerBook.  These make PCMCIA work for me anyways:

include memory 0xa0003000-0xa0ffffff
include port 0x9100-0x9fff

   Remove any other include memory/port lines to avoid oopses.

   It would really be nice if yenta_socket could be cleaned up and this stuff
could be autodetected.  the algorithm was straightforward I think:

>From /proc/iomem, find the card services region and use a suitable sized
region starting after that (assuming it is free).

>From /proc/ioports, find the PCI entry for cardbus and use the ports available
directly after the last cardbus slot for a suitable sized region.

What doesn't work right now:
- dmasound is aweful (lots of clicking and sounds bad)
- video issues in XFree86 and fbdev, along with sleeping
    - closing the screen causes lots of garbling on the screen.
- v.92 modem (hcfusb doesn't work on it)

With a current benh kernel? Do the latest TiBooks have different sound
hardware again?

Sleep doesn't even work with the 7500 Mobility yet, let alone the 9000
Mobility. Otherwise, people have reported moderate success with radeonfb
from the current benh tree and my DRI snapshot Debian packages.

According to the device-tree, it seems to be a snapper (tas3004),
maybe we don't set some i2s registers properly, I don't know.
The device-tree also imply that it supports 2 sample rates,
it's possible that the sample rate or format on i2s side doesn't
match what is configured in the texas chip.

The remaining problem seem to be the same as desktop r9000's with ADC
connector, that is a palette issue. According to Ani, the DACs are
physical (that is, regardless of CRTC1 or 2 usage, the DACs for each
output is fixed, and we may not be configuring the palette in the
proper one).
