The original edid_get_timing() function returns the first valid timing,
but on some plaforms, we could only supports a subset of the listed
monitot's navite timing.
Let's introduce a edid_get_timing_validate() adding a mode_valid callback
including a private cookie pointer.
If the callback returns false, the current timing is discared and the next
one is checked. If no valid & supported timings are found, the function
would return an error.

in case of bmp_logo, the video_bmp driver is used for
drawing a bmp logo. This driver supports only "full"
bmp data. Adding a logo with the bmp_logo tool to
u-boot binary adds currently only real data and drops
the bmp header.
This patch adds now the full bmp data to the u-boot
binary, so video_bmp driver works with the logo embedded
into u-boot.

ttyO2 console enables legacy CONFIG_SERIAL_OMAP driver in kernel.
Nowadays it's preferred to use the generic CONFIG_SERIAL_8250_OMAP
driver, which being enabled via ttyS2 console. Both drivers are enabled
in multi_v7_defconfig and in omap2plus_defconfig, for compatibility
reasons. Let's switch to ttyS2 console, to be sure that standard 8250
serial driver is used.
Similar behavior can be also achieved by enabling
CONFIG_SERIAL_8250_OMAP_TTYO_FIXUP option in kernel, but it's better not
to rely on that, as it can be disabled or removed after transitional
period.
Right now on DRA7/AM57x platforms the 8250-omap driver is being probed
first, and omap-serial driver is only probed if the first one failed.
It can be seen from uart3 definition in arch/arm/boot/dts/dra7-l4.dtsi:
compatible = "ti,dra742-uart", "ti,omap4-uart";
So the kernel already uses 8250 driver. This change basically allows
kernel developers to throw away the omap-serial driver and associated
compatibility options. Similar discussions [1,2] have started several
years ago, so it should be safe to do that now.

If UHS speed modes are enabled, a compatible SD card switches down to 1.8V
during enumeration. If after this a software reboot/crash takes place and
on-chip ROM tries to enumerate the SD card, the difference in
IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card.
The fix for this is to have support for power cycling the card in
hardware (with a PORz/soft-reset line causing a power cycle of the card).
Because the beaglebone X15 (rev A,B and C), am57xx-evms and am57xx-idks don't
have this capability, disable voltage switching for these boards.
The major effect of this is that the maximum supported speed mode is now
high speed(50 MHz) down from SDR104(200 MHz).

During a short period when the bus voltage is switched from 3.3v to 1.8v,
(to enumerate UHS mode), the mmc module is disabled and the mmc IO lines
are kept in a state according to the programmed pad mux pull type.
According to 4.2.4.2 Timing to Switch Signal Voltage in "SD Specifications
Part 1 Physical Layer Specification Version 5.00 February 22, 2016", the
host should hold CLK low for at least 5ms.
In order to keep the card line low during voltage switch, the pad mux of
mmc1_clk line should be configured to pull down.
Add a new pinctrl group for clock line without pullup to be used in boards
where mmc1_clk line is not connected to an external pullup.
