e2b0a8e1e6 drm/radeon/kms: add hw_i2c module option
Turn off hw i2c by default except for mm i2c which
is hw only until we sort out the remaining prescale
issues on older chips.  hw i2c can be enabled with
hw_i2c=1.

ac1aade687 drm/radeon/kms: use new pre/post_xfer i2c bit algo hooks
This allows us to remove the internal bit algo bus used by
the radeon i2c algo.  We now register a radeon algo adapter
if the gpio line is hw capable and the hw inplementation is
available, otherwise we register a bit algo adapter.

f46c01208d drm/radeon/kms: display watermark updates (v2)
- Add module option to force the display priority
  0 = auto, 1 = normal, 2 = high
- Default to high on r3xx/r4xx/rv515 chips
  Fixes flickering problems during heavy acceleration
  due to underflow to the display controllers
- Fill in minimal support for RS600

v2 - update display priority when bandwidth is updated
so the user can change the parameter at runtime and it
will take affect on the next modeset.

9f998ad7e9 drm/radeon/kms: minor fixes for eDP with LCD* device tags (v2)
Some systems have LCD* rather than DFP* device tags in the bios
for eDP connectors; notably the new apple iMac. This fixes
things up so eDP connectors with either tag will work.

5f77df368c drm/radeon/r6xx/r7xx: CS parser fixes
- Drop some more safe regs taht userspace shouldn't hit
- Constant base regs need relocs.  This allows us to use
constant buffers rather than the constant register file.
Also we don't want userspace to be able to set arbitrary
mc base values for the const caches.
- Track SQ_CONFIG so we know whether userspace is using
the cfile or constant buffers.

fcbc451ba1 drm/radeon/kms: Fix NULL pointer dereference if memory allocation failed.
When there is allocation failure in radeon_cs_parser_relocs parser->nrelocs
is not cleaned. This causes NULL pointer defeference in radeon_cs_parser_fini
when clean up code is trying to loop over the relocation array and free the
objects.

Fix adds a check for a possible NULL pointer in clean up code.

d835933436 usb: r8a66597-hcd: fix removed from an attached hub
fix the problem that when a USB hub is attached to the r8a66597-hcd and
a device is removed from that hub, it's likely that a kernel panic follows.

9ce669a892 USB: xhci: Make endpoint interval debugging clearer.
The xHCI hardware can only handle polling intervals that are a power of
two.  When we add a new endpoint during a bandwidth allocation, and the
polling interval is rounded down to a power of two, print the original
polling interval in the endpoint descriptor.

f09a15e6e6 USB: Fix usb_fill_int_urb for SuperSpeed devices
USB 3 and Wireless USB specify a logarithmic encoding of the endpoint
interval that matches the USB 2 specification.  usb_fill_int_urb() didn't
know that and was filling in the interval as if it was USB 1.1.  Fix
usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case
alone, because David Vrabel wants to keep the old encoding.

Update the struct urb kernel doc to note that SuperSpeed URBs must have
urb->interval specified in microframes.

Add a missing break statement in the usb_submit_urb() interrupt URB
checking, since wireless USB and SuperSpeed USB encode urb->interval
differently.  This allows xHCI roothubs to actually register with khubd.

e549a17f69 USB: cp210x: Remove double usb_control_msg from cp210x_set_config
This patch removes a double usb_control_msg that sets the cp210x
configuration registers a second time when calling cp210x_set_config.
For data sizes >2 the second write gets corrupted.
The patch has been created against 2.6.34-rc1, but all cp210x driver
revisions are affected.
