Archit Taneja 6af9cd1431 OMAP2PLUS: DSS2: Generalize naming of PRCM related clock enums in DSS driver
enum dss_clock structure is replaced with generic names that
could be used across OMAP2420, 2430, 3xxx, 44xx platforms.

Sumit Semwal 872462cdfc OMAP2PLUS: clocks: Align DSS clock names and roles
Currently, clock database has <dev, clock-name> tuples for DSS2. Because of
this, the clock names are different across different OMAP platforms.

This patch aligns the DSS2 clock names and roles across OMAP 2420, 2430, 3xxx,
44xx platforms in the clock databases, hwmod databases for opt-clocks, and DSS
clock handling.

This ensures that clk_get/put/enable/disable APIs in DSS can use uniform role
names.

Senthilvadivu Guruswamy ef631f8250 OMAP2,3: DSS2: Get DSS IRQ from platform device
DSS IRQ number can be obtained from platform_get_irq().  This API in turn
picks the right IRQ number belonging to HW IP from the hwmod database.
So hardcoding of IRQ number could be removed.

This IRQ is stored in dss_irq as part of dss structure, and freed it in
dss_exit().

Senthilvadivu Guruswamy c8aac01b7b OMAP2, 3: DSS2: DSI: create platform_driver, move init, exit to driver
Hwmod adaptation design requires each of the DSS HW IP to be a platform driver.
So a platform_driver for DSI is created and init exit methods are moved from core.c
to its driver probe,remove. pdev member has to be maintained by its own drivers.

Also, vdds_dsi regulator handling is copied to dsi.c, since vdds_dsi regulator is
needed by dpi_init() too. Board files are updated accordingly to add 2 instances of
vdds_dsi regulator.

DSI platform driver is registered from inside omap_dss_probe, in the order desired.

Senthilvadivu Guruswamy 8b9cb3a8f3 OMAP2, 3: DSS2: Move clocks from core driver to dss driver
All clock management is moved to dss platform driver. clk_get/put APIs use
dss device instead of core platform device.

Hwmod adaptation design requires each of the DSS HW IP to be a platform driver.
So the device name is changed from omapdss to omapdss_dss in 2420, 2430,
3xxx clock database files. Now the core driver "omapdss" only takes care
of panel registration with the custom bus.
core driver also uses the clk_enable() / clk_disable() APIs exposed by DSS for
clock management.
DSS driver would do clock management of clocks needed by DISPC, RFBI, DSI, VENC

TODO:  The clock content would be adapted to omap_hwmod in a seperate series.

Sumit Semwal 8ba775ca0d OMAP2, 3: DSS2: remove forced clk-disable from omap_dss_remove
As part of omap hwmod changes, DSS will not be the only controller of its
clocks. hwmod initialization also enables the interface clocks, and
manages them.
So, when DSS is built as a module, omap_dss_remove doesn't try to disable
all clocks that have a higher usecount.

result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()

This commit makes things use more neutral function names which dont make
implications about the underlying lock.

The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()

This patch also paves the way to switching console_sem from a semaphore to
a mutex.

lcd_device_register may return ERR_PTR, so a check is added for this value
before the dereference.  All of the other changes reorganize the error
handling code in this function to avoid duplicating all of it in the added

In the original code, in one case, the global variable fb_buffer was set to
NULL in error code that appears after this variable is initialized.  This
is done now in all error handling code that has this property.

The semantic match that finds this problem is as follows:

lh7a40x has only been receiving updates for updates to generic code.
The last involvement from the maintainer according to the git logs was
in 2006.  As such, it is a maintainence burden with no benefit.

This gets rid of two defconfigs.

David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

Yannick Heneault 554ec37aca vgacon: check for efi machine
It seems there is a small problem of VGA palette corruption on EFI
machine.  When the kernel initializes the architecture, it checks if the
machine is a EFI machine and assumes that a VGA console can exist.

When it initializes the console in vgacon_startup it checks if it can
really use the VGA console.  I think this is where a check is missing.
Currently, the function can fail if a VESA boot mode is detected but not if
a EFI boot mode was used.

Thus vgacon_startup() doesn't fail and initialize the video card for a real
VGA mode.  This function changes the first 16entries of the VGA palette.

When the efifb driver kicks in, the palette is not restored to default
ramp value, thus the 16 first entry remain in a modified state.  The
following patch prevent this corruption.

Alberto Panizzo aff5ce6ca8 drivers/video/backlight/l4f00242t03.c: fix reset sequence
The reset command is part of the init sequence and it take effect
only if the lcd is powered.

The effect of the bug was that the sequence:
set lcd power_state to FB_BLANK_POWERDOWN
set lcd power_state to FB_BLANK_UNBLANK
Did not produced a complete reboot of the LCD which was showing fuzzy
colours.

This was not experienced before implementing correctly all the LCD power
states with the patch [1].  Since before the patch [1] the regulators were
not touched and the LCD shutdown was reached with a register write.  After
the patch [1] a complete boot sequence with an initial reset is needed for
the display every time the LCD is powered up.

will use the default 720p video mode. If a command line option of the
form "video=sh_mobile_lcdc:<width>x<height>@<refresh>" is provided,
the driver will look for that mode among those, available in the
monitor EDID. This patch adds the ability to request the driver to
use monitor's preferred mode by specifying 0 as width and hight in
the above string. If that mode is not supported by the system, the
driver will continue scanning through EDID modes, until it finds a
suitable one.

The root cause of the panic is the race between the resume and reconnect to the backend.

Clearing the 'update_wanted' flag of xenfb before disconnecting from the

Sumit Semwal 18faa1b68a OMAP: DSS2: Introduce omap_channel as an omap_dss_device parameter, add new overlay manager.
A panel connects to one of the overlay managers of DSS through some interface block.
On OMAP4, specifying the type of the display is not sufficient to conclude which manager
the panel should be connected to.
Hence, a new member 'channel' is introduced in omap_dss_device structure to determine
which manager the panel uses. The dss_recheck_connections() called in dss_driver_probe()
uses this channel parameter to set the correct manager to the corresponding omap_dss_device.

The channel parameter is used only once to ensure the correct managers are set for each
panel. The parameter dssdev->manager->id will take care of ensuring that the panel and
then the interface driver configures the correct DISPC channel.

Also, add a new Overlay Manager in manager.c, make other changes needed for LCD2 channel.

Sumit Semwal 8613b0005d OMAP: DSS2: Represent DISPC register defines with channel as parameter
On OMAP4, we have a new DISPC channel for Overlay Manager LCD2. There is a set
of regsiters for LCD2 channel similar to the existing LCD channel, like
DISPC_CONTROL2, DISPC_DIVISOR2, DISPC_CONFIG2 and so on.

Introduce new enum members for LCD2 Channel and corresponding Overlay Manager
in display.h.

Represent the following DISPC register defines with channel as a parameter
to differentiate between LCD and LCD2 registers (and also DIGIT in some cases):

DISPC_DEFAULT_COLOR, DISPC_TRANS_COLOR, DISPC_TIMING_H, DISPC_TIMING_V,
DISPC_POL_FREQ, DISPC_DIVISOR, DISPC_SIZE_LCD, DISPC_DATA_CYCLEk,
DISPC_CPR_COEF_R, DISPC_CPR_COEF_G and DISPC_CPR_COEF_B

This parametrization helps in reducing the number of register defines for DISPC.
Replace the existing reads/writes to these registers in this new way.
Also, Introduce defines for registers DISPC_CONTROL2 and DISPC_CONFIG2 which
are used exclusively for LCD2 channel.

David S. Miller 09798eb947 atyfb: Fix bootup hangs on sparc64.
After commit 25edd6946a ("sparc64: Get
rid of indirect p1275 PROM call buffer.")  we can't pass virtual
addresses >4GB to PROM calls.

Largely this is never necessary in drivers because we have a copy of
the entire PROM device tree in the kernel and a set of of_*()
interfaces to access it.

Unfortunately there were some lingering prom calls in the atyfb
driver, in particular prom_finddevice() was being called with an
on-stack address which could be anywhere.

This code is actually probing for information we already have, the
PROM choosen console output device is stored in of_console_device so
all of this nasty code consolidates into a one-line comparison.

Next we have some prom_getintdefault() calls which are trivially
transformed into the equivalent of_getintprop_default().

Special thanks to Fabio, who figured out exactly where the bootup
was hanging.  That made this bug trivial to fix.

Stefani Seibold 748103e723 drivers/video/i810/i810-i2c.c: fix i2c bus handling
These patch fix a longstanding bug in the i810 frame buffer driver.

The handling of the i2c bus is wrong: A 1 bit should not written to the
i2c, these will be done by switch the i2c to input. Driving an 1 bit
active is against the i2c spec.

An active driven of a 1 bit will result in very strange error, depending
which side is the more powerful one. In my case it depends on the
temperature of the Display-Controller-EEprom: With an cold eprom a got
the correct EDID datas, with a warm one some of the 1 bits was 0 :-(

The same bug is also in the intelfb driver in the file
drivers/video/intelfb/intelfb_i2c.c. The functions intelfb_gpio_setscl()
and intelfb_gpio_setsda() do drive the 1 bit active to the i2c bus. But
since i have no card which is used by the intelfb driver i cannot fix
it.

Brent Cook 529ed806d4 video: Fix the HGA framebuffer driver
Resurrected some old hardware and fixed up the hgafb driver to work
again. Only tested with fbcon, since most fbdev-based software appears
to only support 12bpp and up. It does not appear that this driver has
worked for at least the entire 2.6.x series, perhaps since 2002.

Hercules graphics hardware uses packed pixels horizontally, but rows are
not linear. In other words, the pixels are not packed vertically. This
means that custom imageblit, fillrect and copyarea need to be written
specific to the hardware.

 * Removed the experimental acceleration option, since it is required
   for the hardware to work.
 * Fixed imageblit to work with fb_image's wider than 8 pixels.
 * Updated configuration text (HGA hardware is from 1984)

Magnus Damm 417d48274e fbdev: sh_mobile_lcdcfb: Enable 32 bpp and 24 bpp support
This patch extends the LCDC driver with 24 bpp
and 32 bpp support.

These modes have been kept disabled earlier due
to dependencies between the potential two LCDC
channels that are exported as two separate
framebuffer devices. The dependency boils down
to a byte swap register that is shared between
multiple channels.

With this patch applied all single channel LCDC
hardware can chose freely from 16, 24 and 32 bpp.
Dual channel LCDC must stick to the same setup
for both channels.

Without this patch only 16 bpp is fully supported.

This adds a driver for the the 2D graphics accelerator found on PXA3xx
processors. Only resource mapping, interrupt handling and a simple ioctl
handler is done by the kernel part, the rest of the logic is implemented
in DirectFB userspace.

Graphic applications greatly benefit for line drawing, blend, and
rectangle and triangle filling operations.

Benchmarks done on a PXA303 using the df_dok benchmarking tool follow,
where the value in square brackets show the CPU usage during that test.

Without accelerator (benchmarking 256x252 on 480x262 RGB16 (16bit)):

build dependency so that old omapfb depends on OMAP1/2/3, fixing the

Andrew Kephart e504b84805 fbdev: Fix fb_find_nearest_mode refresh comparison
Refresh rate nearness is not calculated or reset when nearest resolution
changes.

This patch resets the refresh rate differential measurement whenever a
new nearest resolution is discovered.  This fixes two error cases;
first, wherein the first mode's refresh rate differential is never
calculated and second, when the closest refresh rate from a previous
nearest resolution is erroneously preserved.

Daniel Drake 16cdd4336f lxfb: Maintain video processor palette through suspend/resume
The Geode X driver uses both of the LX's palettes, one for gamma
correction and one for colormaps.

The kernel driver currently only backs up the one used for colormaps
during suspend/resume. If you mess with gamma settings and do a
suspend/resume, colors go funny.

Fix this by backing up the video proc palette during suspend/resume,
alongside the display controller one which is already handled.

Caglar Akyuz 93c176f39f video: da8xx: Register IRQ as last thing in driver probing.
Following commit exposed a bug in driver:

	"fbdev: da8xx/omap-l1xx: implement double buffering"

Bug is, if interrupt handler is called before initialization is
finished, raster controller is enabled and following register
modifications causes hardware to stay in a broken state.

By looking at this one may say that proper locking is missing in
this driver, and a more proper fix should be prepared. However,
aformentioned commit causes a regression in the driver and some
fix to current one should be applied first.

Dan Carpenter 1e7c780488 fbcmap: integer overflow bug
There is an integer overflow in fb_set_user_cmap() because cmap->len * 2
can wrap.  It's basically harmless.  Your terminal will be messed up
until you type reset.

This patch does three things to fix the bug.

First, it checks the return value of fb_copy_cmap() in fb_alloc_cmap().
That is enough to fix address the overflow.

Second it checks for the integer overflow in fb_set_user_cmap().

Lastly I wanted to cap "cmap->len" in fb_set_user_cmap() much lower
because it gets used to determine the size of allocation.  Unfortunately
no one knows what the limit should be.  Instead what this patch does
is makes the allocation happen with GFP_KERNEL instead of GFP_ATOMIC
and lets the kmalloc() decide what values of cmap->len are reasonable.
To do this, the patch introduces a function called fb_alloc_cmap_gfp()
which is like fb_alloc_cmap() except that it takes a GFP flag.

dark).  Writing a value between 1..3 forces the backlight controller to
enter the corresponding Ambient Light Zone.  Writing 0 returns to normal
operation.

Fix valid range checking so we don't write invalid values to the
controller, and make sure we subtract 1, since this is what the register
definition (CFGR:BLV) requires.  Otherwise the values written don't work
correctly.

Arun Murthy fef7764f8b backlight: add low threshold to pwm backlight
The intensity of the backlight can be varied from a range of
max_brightness to zero.  Though most, if not all the pwm based backlight
devices start flickering at lower brightness value.  And also for each
device there exists a brightness value below which the backlight appears
to be turned off though the value is not equal to zero.

If the range of brightness for a device is from zero to max_brightness.  A
graph is plotted for brightness Vs intensity for the pwm based backlight
device has to be a linear graph.

intensity
	  |   /
	  |  /
	  | /
	  |/
	  ---------
	 0	max_brightness

But pratically on measuring the above we note that the intensity of
backlight goes to zero(OFF) when the value in not zero almost nearing to
zero(some x%).  so the graph looks like

intensity
	  |    /
	  |   /
	  |  /
	  |  |
	  ------------
	 0   x	 max_brightness

In order to overcome this drawback knowing this x% i.e nothing but the low
threshold beyond which the backlight is off and will have no effect, the
brightness value is being offset by the low threshold value(retaining the
linearity of the graph).  Now the graph becomes

intensity
	  |     /
	  |    /
	  |   /
	  |  /
	  -------------
	   0	  max_brightness

With this for each and every digit increment in the brightness from zero
there is a change in the intensity of backlight.  Devices having this
behaviour can set the low threshold brightness(lth_brightness) and pass
the same as platform data else can have it as zero.
