node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

It makes not sense using u8 to hold a value on a 32-bit or 64-bit machine.
It can only bloat the code by forcing the compiler to mask the value.
Change it to uint.

Compiling the 'bmp' command with DM and having one of the following macros
enabled:
CONFIG_BMP_16BPP, CONFIG_BMP_24BPP ONFIG_BMP_32BPP
generates this error:
drivers/video/video_bmp.c: In function ‘video_bmp_display’:
drivers/video/video_bmp.c:315:22: error: ‘lcd_line_length’ undeclared (first use in this function)
fb -= width * 2 + lcd_line_length;

This patch moves to using the correct variable instead and enables the

Now that all x86 boards have been converted to DM video, drop the

With DM VESA driver on x86 boards, plat->base/size/align are all
zeroes and starting address passed to alloc_fb() happens to be 1MB
aligned, so this routine does not trigger any issue. On QEMU with
U-Boot as coreboot payload, the starting address is within 1MB
range (eg: 0x7fb0000), thus causes failure in video_post_bind().
Actually if plat->size is zero, it makes no sense to do anything
in this routine. Add such check there.

When the backlight's pwm input is connected to a pwm output of the SoC,
actually use pwm to drive the backlight.
The mean reason for doing this is to fix the backlight turning off
for aprox. 1 second while the kernel is booting. This is caused by
the kernel actually using pwm to drive the backlight, so that it
can dim the backlight. First the pwm driver loads and switches the
pinmux for the pin driving the backlight's pwm input to the pwm
controller. Then about 1s later the actual backlight driver loads
and tells the pwm driver to actually update the pwm settings, which
have a power-on-reset value of "off".
An additional advantage is that this allows us to initatiate the
backlight at 80%, which is the kernel default, avoiding a brightness
change while the kernel loads.
