fbdev: select versatile helpers for the integrator

2015-10-28T02:13:55+00:00

[ Upstream commit 2701fa0864ecb9e49d47a4aa1c02f172ab79639a ]

Commit 11c32d7b6274cb0f554943d65bd4a126c4a86dcd
"video: move Versatile CLCD helpers" missed the fact
that the Integrator/CP is also using the helper, and
as a result the platform got only stubs and no graphics.
Add this as a default selection to Kconfig so we have
graphics again.

video/fbdev: fix defio's fsync

2015-01-27T16:29:39+00:00

commit 30ea9c5218651bc11cbdba7820be78f04e2d83bc upstream.

fb_deferred_io_fsync() returns the value of schedule_delayed_work() as
an error code, but schedule_delayed_work() does not return an error. It
returns true/false depending on whether the work was already queued.

Fix this by ignoring the return value of schedule_delayed_work().

video/logo: prevent use of logos after they have been freed

2015-01-27T16:29:39+00:00

commit 92b004d1aa9f367c372511ca0330f58216b25703 upstream.

If the probe of an fb driver has been deferred due to missing
dependencies, and the probe is later ran when a module is loaded, the
fbdev framework will try to find a logo to use.

However, the logos are __initdata, and have already been freed. This
causes sometimes page faults, if the logo memory is not mapped,
sometimes other random crashes as the logo data is invalid, and
sometimes nothing, if the fbdev decides to reject the logo (e.g. the
random value depicting the logo's height is too big).

This patch adds a late_initcall function to mark the logos as freed. In
reality the logos are freed later, and fbdev probe may be ran between
this late_initcall and the freeing of the logos. In that case we will
miss drawing the logo, even if it would be possible.

OMAPDSS: DSI: Fix PLL_SELFEQDCO field width

2014-10-22T08:33:16+00:00

PLL_SELFREQDCO bitfield is from bit 3 to 1, but the driver writes bits
from 4 to 1. The bit 4 is 'reserved', so this probably should not cause
any issues, but it's better to fix it.

OMAPDSS: fix dispc register dump for preload & mflag

is not dumped for GFX.

OMAPDSS: HDMI: fix regsd write

2014-10-22T08:11:18+00:00

HDMI PLL's REGSD field is only set by the driver if the PLL's output
clock is over 1GHz. This is clearly an error, as REGSD should be set
always.

OMAPDSS: HDMI: fix PLL GO bit handling

2014-10-22T08:07:54+00:00

The PLL settings are committed by setting GO bit, which is then cleared
by the HW when the settings have been taken into use.

The current PLL code handles this wrong: instead of waiting for the bit
to be cleared, it waits for the bit to be set. Usually, the bit is
always set, as the CPU has just set it before. However, if the CPU takes
enough time between setting the GO bit and checking it, the HW may
already have cleared the bit and this leads to timeout error.

Fix the wait to check the bit properly.
