Tomi Valkeinen a38bb793ea OMAPDSS: fix regression with display sysfs files
omapdss's sysfs directories for displays used to have 'name' file,
giving the name for the display. This file was later renamed to
'display_name' to avoid conflicts with i2c sysfs 'name' file. Looks like
at least xserver-xorg-video-omap3 requires the 'name' file to be
present.

To fix the regression, this patch creates new kobjects for each display,
allowing us to create sysfs directories for the displays. This way we
have the whole directory for omapdss, and there will be no sysfs file
clashes with the underlying display device's sysfs files.

We can thus add the 'name' sysfs file back.

Tomi Valkeinen a2408154a1 OMAPDSS: DPI: DRA7xx support
Add support for DRA7xx DPI output.

DRA7xx has three DPI outputs, each of which gets its input from a DISPC
channel. However, DRA72x has only one video PLL, and DRA74x has two
video PLLs. In both cases the video PLLs need to be shared between
multiple outputs. The driver doesn't handle this at the moment.

Also, DRA7xx requires configuring CONTROL module bits to route the clock
from the PLL to the used DISPC channel.

Tomi Valkeinen a87a6d6b09 OMAPDSS: encoder-tpd12s015: Fix race issue with LS_OE
A race issue has been observed with the encoder-tpd12s015 driver, which
leads to errors when trying to read EDID. This has only now been
observed, as OMAP4 and OMAP5 boards used SoC's GPIOs for LS_OE GPIO. On
dra7-evm boards, the LS_OE is behind a i2c controlled GPIO expander,
which increases the time to set the LS_OE.

This patch simplifies the handling of the LS_OE gpio in the driver by
removing the interrupt handling totally. The only time we actually need
to enable LS_OE is when we are reading the EDID, and thus we can just
set and clear the LS_OE gpio inside the read_edid() function.

This also has the additional benefit of very slightly decreasing the
power consumption.

Tomi Valkeinen 4d073292a7 fbdev: fix CVT vertical front and back porch values
CVT v1.1 spec says: "the vertical front porch shall in all cases be
fixed to 3 lines". The code in fbcvt.c instead sets the _back_ porch to
3 (plus margin).

After swapping cvt.v_front_porch and cvt.v_back_porch the resulting
timings were in line with CVT timings in VESA DMT spec.

The bug seems to be more than 9 years old, but I presume it has not been
noticed as usually the video timings come from the EDID or from the
timing tables in fbdev, and probably swapped values for vfp and vbp work
fine for most of the displays.

David Ung 72bbf10bf0 video: fbdev: Validate mode timing against monspec
fbmon may generate mode timings that are out of spec of the monitor.
eg DELL U2410 has a max clock 170mhz but advertises a resolutions of
1920x1200@60 in its Standard Timings using 2byte code of D1 00.
When this is looked up in the DMT table it gives it a 193mhz clock.
Although the DELL monitor supports 1920x1200@60, it can only run with
reduced timings at 154mhz or DMT id 0x44 which has no STD 2byte code.
This patch checks to see if the mode can be supported by the monitor
by comparing against monspecs.dclkmax.

David Ung 8f5ee77bb8 video: fbdev: Check Standard Timing against DMT
Add the VESA Display Monitor Timing (DMT) table.
During parsing of Standard Timings, it compare the 2 byte STD code
with DMT to see what the VESA mode should be.  If there is no entry
in the vesa_modes table or no match found, it fallsback to the
GTF timings.

commit 765d5b9c2b ("fbdev: fbcon: select
VT_HW_CONSOLE_BINDING") made FRAMEBUFFER_CONSOLE always select
VT_HW_CONSOLE_BINDING, but forgot to remove

	select VT_HW_CONSOLE_BINDING if FRAMEBUFFER_CONSOLE

from the individual drivers' sections that already did this before.

Geert Uytterhoeven 8f5b1e6511 console/dummy: Move screen size selection from CPP to Kconfig
PA-RISC already handled the dummy console screen size selection in
Kconfig, so generalize this to other platforms.

ARM keeps on using screen_info, which is filled in by
platform-specific code, or from ATAGS.

we'd better use dma_addr_t instead of phys_addr_t. Because the
address we got in fact is DMA or bus address for the platform.

Mathias Krause a8fc91afab atyfb: mark DMI system id table as __initconst
We can mark the DMI system id table as __initconst by using a helper
variable that'll tell us if we need to unregister the reboot notifier in
atyfb_exit() instead of matching the DMI system id again.

This frees up ~680 bytes of runtime memory, the DMI table occupies.
