USB: io_ti: fix chars_in_buffer overhead

2013-06-13T17:49:49+00:00

commit b16634adce951a7371be931487034f7365971ed0 upstream.

Use the new generic usb-serial wait_until_sent implementation to wait
for hardware buffers to drain.

This removes the need to check the hardware buffers in chars_in_buffer
and thus removes the overhead introduced by commit 263e1f9f ("USB:
io_ti: query hardware-buffer status in chars_in_buffer") without
breaking tty_wait_until_sent (used by, for example, tcdrain, tcsendbreak
and close).

USB: ftdi_sio: fix chars_in_buffer overhead

2013-06-13T17:49:49+00:00

commit a37025b5c702aaf87191cd75fcc42c54454f16f5 upstream.

Use the new generic usb-serial wait_until_sent implementation to wait
for hardware buffers to drain.

This removes the need to check the hardware buffers in chars_in_buffer
and thus removes the overhead introduced by commit 6f602912 ("usb:
serial: ftdi_sio: Add missing chars_in_buffer function") without
breaking tty_wait_until_sent (used by, for example, tcdrain, tcsendbreak

USB: serial: add generic wait_until_sent implementation

2013-06-13T17:49:48+00:00

commit dcf0105039660e951dfea348d317043d17988dfc upstream.

Add generic wait_until_sent implementation which polls for empty
hardware buffers using the new port-operation tx_empty.

The generic implementation will be used for all sub-drivers that
implement tx_empty but does not define wait_until_sent.

drm/i915: force full modeset if the connector is in DPMS OFF mode

2013-06-13T17:49:47+00:00

commit e3de42b68478a8c95dd27520e9adead2af9477a5 upstream.

Currently the driver's assumed behavior for a modeset with an attached
FB is that the corresponding connector will be switched to DPMS ON mode
if it happened to be in DPMS OFF (or another power save mode). This
wasn't enforced though if only the FB changed, everything else (format,
connector etc.) remaining the same. In this case we only set the new FB
base and left the connector in the old power save mode.

Fix this by forcing a full modeset whenever there is an attached FB and
any affected connector is in a power save mode.

V_2: Run the test for encoders in power save mode outside the the
test for fb change: user space may have just disabled the encoders
but left everything else in place. Make sure the connector list is
not empty before running this test.

radeon: use max_bus_speed to activate gen2 speeds

2013-06-13T17:49:44+00:00

commit 7e0e41963740525af702bb23edede8ae9afc4ac0 upstream.

radeon currently uses a drm function to get the speed capabilities for
the bus, drm_pcie_get_speed_cap_mask. However, this is a non-standard
method of performing this detection and this patch changes it to use
the max_bus_speed attribute.

pci: Set dev->dev.type in alloc_pci_dev

2013-06-13T17:49:41+00:00

commit 88e7b167a079f090405ab4390b629b5effdab41a upstream.

Set dev->dev.type in alloc_pci_dev so that archs that have their own
versions of pci_setup_device get this set properly in order to ensure
things like the boot_vga sysfs parameter get created as expected.
