tty: serial: 8250: tegra: irq 68: nobody cared workaround

2012-12-17T12:27:29+00:00

The irq request flag sometimes does not get reset or is asserted
immediately, but iir does not indicated this, if so ISR is entered with
iir set to 0xc1, i.e. no irq pending.
Try enabling the transmit register empty interrupt, iir becomes 0xc2,
irq gets de-asserted and ier is reverted by the regular code flow in
the ISR.
We try this every 4096 spurious irq.

net: asix: revise Ethernet MAC address assignment

2012-12-05T15:20:01+00:00

Revise Ethernet MAC address assignment: should now use MAC from EEPROM
if set and further handles up to two instances of custom user MACs (2nd
one with a 0x100000 offset). This way customer does not have to put
EEPROM on a secondary Ethernet on the carrier board and still gets a
valid official MAC address from us (e.g. analogous to how we did it on
our Protea carrier board).

tegra: udc: fix spurious whitespace in log message

Fix spurious whitespace in Tegra's UDC driver log message.

colibri_t20: USB: fix building device controller driver as module

2012-11-20T15:30:14+00:00

Trying to build USB device controller driver as a module failed as
follows:

ERROR: "g_usb_high_speed" [drivers/usb/gadget/tegra_udc.ko] undefined!

This is due to a missing export of above mentioned global variable.

colibri_t20: USB: allow forcing full speed only

2012-11-20T09:00:04+00:00

Allow limiting externally accessible USB OTG and host port to full
speed only in order to be compatible with older carrier boards (e.g.
old Colibri Evaluation Board v2.1c, Orchid or Protea). The following
kernel argument can be set to either 0 meaning false or 1 meaning true:

usb_high_speed

USB: ehci: tegra: fix USB1 port reset issue

2012-11-19T12:05:21+00:00

Tegra USB1 port needs to issue Port Reset twice internally, otherwise it
fails to enumerate devices attached to it

android: dc: tegra: video: conditionally revert timestamp support

2012-11-16T16:13:59+00:00

Android R14 userspace seems to have issues with timestamp support:

[   14.764337] host1x host1x: SurfaceFlinger: syncpoint id 8 (disp0_a) stuck waiting 3, timeout=2147483447
[   14.773845] host1x host1x: id 8 (disp0_a) min 2 max 4
[   14.779163] host1x host1x: id 9 (disp1_a) min 2 max 4

[   14.789586] host1x host1x: id 20 (disp0_b) min 2 max 4
[   14.794889] host1x host1x: id 21 (disp1_b) min 2 max 4
[   14.800241] host1x host1x: id 22 (3d) min 77 max 95

[   14.826810] host1x host1x: waitbase id 3 val 77

Therefore conditionally revert it in that case for now.

usb: otg: colibri_t20: notify USB events to otg core

2012-11-14T10:02:43+00:00

Notify USB connection events to otg core. These notifications will be
used by drivers (e.g. otg wakelock driver) who registered for the
events.

See a4c597152f0b69ba1172b3d52d4e9d39ea3bbd53.
