Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2012-03-27T23:03:32+00:00

Pull "ARM: global cleanups" from Arnd Bergmann:
 "Quite a bit of code gets removed, and some stuff moved around, mostly
  the old samsung s3c24xx stuff.  There should be no functional changes
  in this series otherwise.  Some cleanups have dependencies on other
  arm-soc branches and will be sent in the second round.

Fixed up trivial conflicts mainly due to #include's being changes on
both sides.

OMAPDSS: register dss drivers in module init

2012-03-21T12:55:15+00:00

We do the dss driver registration in a rather strange way: we have the
higher level omapdss driver, and we use that driver's probe function to
register the drivers for the rest of the dss devices.

There doesn't seem to be any reason for that, and additionally the
soon-to-be-merged patch "ARM: OMAP: omap_device: remove
omap_device_parent" will break omapdss initialization with the current
registration model.

This patch changes the registration for all drivers to happen at the
same place, in the init of the module.

OMAPDSS: APPLY: fix clearing shadow dirty flag with manual update

2012-03-13T13:46:21+00:00

Currently the shadow-dirty flags for manual update displays is cleared
in the apply_irq_handler when an update has finished. This is not
correct, as the shadow registers are taken into use (i.e. after that
they are not dirty) when the update is started.

Move the mgr_clear_shadow_dirty() call from apply_irq_handler to
dss_mgr_start_update() to fix this.

OMAPDSS: APPLY: print warning if wait_pending_extra_info_updates fails

2012-03-06T12:08:39+00:00

wait_pending_extra_info_updates() currently does a hacky second check
for extra_info_update_ongoing() at the end of the function to show a
warning if extra_info update is still ongoing. The call to
extra_info_update_ongoing() should really be inside spinlock, but that's
a bit heavy just for verification.

Rather than that, check the return value of the
wait_for_completion_timeout() and print an error if it has timeouted or
returned an error.

Even better would be to return the error value and act on it in the
callers of wait_pending_extra_info_updates. However, it's not clear what
the callers should do in case of an error, as the error should only
happen if there's a bug in the driver or the HW. So we'll just print the
warning for now.

OMAPDSS: MANAGER/APPLY: Add runtime_pm protection around wait_for_go/vsync functions

2012-03-06T12:08:30+00:00

If DSS suspends within the functions dss_mgr_wait_for_go(),
dss_mgr_wait_for_go_ovl() or dss_mgr_wait_for_vsync(). It may lose it's clock
and lead to a register access failure.

Request runtime_pm around these functions.

then calling them from omap_dispc_wait_for_irq_interruptible_timeout()]

2012-03-06T12:08:23+00:00

coef3_M8 had an incorrect phase with 50% more intensity. This resulted in
banding on slightly down/upscaled images. Fixed a rounding error in coef5_M9.

Also removed ARRAY_LEN macro as ARRAY_SIZE is the standard linux one.

Add missing but supported color formats for GFX pipeline in dss features:
RGBX16-4444, RGBA16-4444 and XRGB16-1555.

In dispc_ovl_set_color_mode():

- Remove unsupported modes on GFX pipeline: YUV2 and UYVY. Replace these by
  missing modes supported by GFX pipelines: RGBX16-4444 and RGBA16-4444.

- Fix swapped modes on VID pipelines: RGBX16-4444 and XRGB16-4444.

OMAPDSS: HDMI: Add M2 divider while calculating clkout

2012-03-06T12:08:10+00:00

While calculating regm and regmf value add using M2 divider in
the equation.
Formula for calculating:
Output clock on digital core domain:
	CLKOUT = (M / (N+1))*CLKINP*(1/M2)
Internal oscillator output clock on internal LDO domain:
	CLKDCOLDO = (M / (N+1))*CLKINP
The current code when allows variable M2 values as input
ignores using M2 divider values in calculation of regm and regmf.
so fix it by using M2 in calculation although the default value for
M2 is 1.
