video: remove unnecessary platform_set_drvdata()

2013-06-26T11:44:40+00:00

The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.

drivers/video/ep93xx-fb.c: fix section mismatch and use module_platform_driver

2013-04-29T22:54:26+00:00

Remove the __init tags from the ep93xxfb_calc_fbsize() and
ep93xxfb_alloc_videomem() functions to fix the section mismatch
warnings.

Use module_platform_driver() to remove the init/exit boilerplate.

drivers/video/ep93xx-fb.c: include for devm_ioremap()

2013-03-22T23:41:20+00:00

Commit be8678149701 ("drivers/video/ep93xx-fb.c: use devm_ functions")
introduced a build error:

Include  to pickup the declaration of 'devm_ioremap'.

Drivers: video: remove __dev* attributes.

2013-01-03T23:57:01+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Merge tag 'fbdev-updates-for-3.7' of git://github.com/schandinat/linux-2.6

2012-10-12T01:21:02+00:00

Pull fbdev updates from Florian Tobias Schandinat:
 "This includes:
   - large updates for OMAP
     - basic OMAP5 DSS support for DPI and DSI outputs
     - large cleanups and restructuring
   - some update to Exynos and da8xx-fb
   - removal of the pnx4008 driver (arch removed)
   - various other small patches"

Fix up some trivial conflicts (mostly just include line changes, but
also some due to the renaming of the deferred work functions by Tejun).

ARM: ep93xx: move platform_data definitions

2012-09-14T09:16:55+00:00

Platform data for device drivers should be defined in
include/linux/platform_data/*.h, not in the architecture
and platform specific directories.

This moves such data out of the ep93xx include directories

drivers/video/ep93xx-fb.c: use devm_ functions

2012-08-23T12:58:24+00:00

The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

drivers/video/ep93xx-fb.c: clean up error-handling code

2012-04-21T21:47:49+00:00

There were two problems in this code: failure of the setup function should
free locally allocated resources like other nearby failures, and the test
if (&info->cmap) can never be false.  To generally clean things up, this
patch reorders the error handling code at the failed label and adds labels
so that the conditionals are not necessary.

ep93xx: Use ioremap for backlight driver

2012-03-14T00:41:10+00:00

The ep93xx backlight driver uses a single register within the
framebuffer's register space. Currently the backlight driver uses a
static IO mapping for the register since the memory cannot be
requested by both drivers.

Convert the static mapping to use ioremap so that we can remove the
dependency on mach/hardware.h. To do so, we need remove the
request_mem_region from both the backlight and framebuffer drivers,
since whichever driver is loaded second will fail with -EBUSY
otherwise.

A proper fix is still required, and a FIXME comment has been added to
both drivers.

video: Add module.h to drivers/video files who really use it.

2011-10-31T23:31:33+00:00

They were getting this implicitly by an include of module.h
from device.h -- but we are going to clean that up and break
that include chain, so include module.h explicitly now.
