7ceb1892c0 video: omap: delete support for early fbmem allocation
Commit 1e434f9318 (OMAPFB: remove early mem
alloc from old omapfb) deleted the support for early fbmem allocation
from the platform code, but some code still remains in the driver side.
Delete this code now, as it repotedly causes build issues on !MMU.

The patch was tested on Amstrad E3 and Nokia 770 and framebuffer
functionality is not affected.

really add any value without the info that the np could

fabd3152fb video/mbx: fix building debugfs support
The mbx framebuffer debugfs support apparently hasn't been able
to build for a long time, at least since 2006 when the u.generic_ip
field in the inode was removed. This fixes the obvious bug, and
also makes it possible to build the driver as a module when
debugfs support is enabled, by simply including the C file.
It's ugly, but it won't make the driver any worse than it
already is, and doesn't require a more invasive change that
might break it further.

81c44c2b2c video/omap: fix modular build
The framebuffer layer can be a loadable module, which forces
omapfb to be a module as well. However, this breaks the lcd
drivers, which are linked into the omapfb driver but each
have their own module_init() function. To solve this,
we split out the lcd drivers into separate modules and
export omapfb_register_panel, which is the only interface
required between the main omapfb driver and the lcd panel
drivers.

We also have to introduce a new Kconfig symbol for H3, since
that lcd driver has a dependency on TPS65010, which we can
express better in Kconfig than Makefile syntax.

423431a3b5 video: sh_mobile_lcdcfb depends on meram
The sh_mobile_lcdcfb driver calls interfaces provided
by the corresponding "meram" helper. This fails if meram
is a module but lcdcfb is built-in.

To work around it, this uses special Kconfig magic to
only allow lcdcfb to be built if
a) both are modules,
b) meram is built-in, or
c) meram is disabled and the helpers stubbed out

Changing meram from 'y' to 'm' now forces clcd to
be a module as well, which seems to be the desired
behavior.

776bbb97e0 video: Kconfig: move drm and fb into separate menus
At the moment the "Device Drivers / Graphics support" kernel config page
looks rather messy, with DRM and fbdev driver selections on the same
page, some on the top level Graphics support page, some under their
respective subsystems.

If I'm not mistaken, this is caused by the drivers depending on other
things than DRM or FB, which causes Kconfig to arrange the options in
not-so-neat manner.

Both DRM and FB have a main menuconfig option for the whole DRM or FB
subsystem. Optimally, this would be enough to arrange all DRM and FB
options under the respective subsystem, but for whatever reason this
doesn't work reliably.

This patch adds an explicit submenu for DRM and FB, making it much
clearer which options are related to FB, and which to DRM.

0925afc9a4 OMAPDSS: fix shared irq handlers
DSS uses shared irq handlers for DISPC and DSI, because on OMAP3, the
DISPC and DSI share the same irq line.

However, the irq handlers presume that the hardware is enabled, which,
in theory, may not be the case with shared irq handlers. So if an
interrupt happens while the DISPC/DSI is off, the kernel will halt as
the irq handler tries to access the DISPC/DSI registers.

In practice that should never happen, as both DSI and DISPC are in the
same power domain. So if there's an IRQ for one of them, the other is
also enabled. However, if CONFIG_DEBUG_SHIRQ is enabled, the kernel will
generate a spurious IRQ, which then causes the problem.

This patch adds an is_enabled field for both DISPC and DSI, which is
used to track if the HW is enabled. For DISPC the code is slightly more
complex, as the users of DISPC can register the interrupt handler, and
we want to hide the is_enabled handling from the users of DISPC.

35762a47c0 backlight: core: Replace kfree with put_device
As per the comments on device_register, we shouldn't call kfree()
right after a device_register() failure. Instead call put_device(),
which in turn will call bl_device_release resulting in a kfree to the
full structure.
