Remove special clocks for Tegra 2, but use backup clock source
instead. This allows to run all common used resolution within
the drivers -1/+9% allowed band for pixelclock exactness.
|
|
Add some more modes e.g. for full HD panel.
Also add tweaked pixel clock for Tegra 2 because the clock is always
a child of the peripherial clock and only some divisors are available.
|
|
Updated several comments to make code easier to read and understand.
Also use the front_porch workaround in any case, for HDMI output
too.
|
|
In order to find a viable resolution we not only parse VESA mode,
we also parse CEA (multimedia) modes and our own small modedb (for
specific touch screens).
|
|
Use new modedb based framebuffer settings by defining default_mode
in the display controllers platform data. Also impelmented the
fallback logic to this default_mode in case no kernel cmd line
parameter was set.
|
|
Allow to specify framebufffer videomode using kernel command line
parameters. NVIDIAs binary X driver later on picks up those settings
and start X with current mode settings, if no EDID data are available.

Android R14 userspace seems to have issues with timestamp support:

Therefore conditionally revert it in that case for now.

Creates a miscdev at /dev/tegra-throughput which gl will use to set a
target frame rate. In addition it receives notifications from dc on
flip events. On each notification the percentage ratio of the actual
frame time to the target frame time is calculated. In subsequent
changes this ratio will be reported to other modules as a throughput
hint.
