The card detect line should also be configured using pinctrl
interface. When pinctrl is enabled on Exynos, the old-style gpio
bindings is not supported. So a pinctrl node for sd2_cmd should be
defined which then can be listed in pinctrl-0.

It should have a more specific compatible value first, i.e.
"hardkernel,odroid-x" or similar.

Bootargs should be passed in from u-boot, don't specify them in the
static device tree.

we need to drop the \ \ stuff it will end with merge conflict
as if you add 2 dtb at the end you will end with 2 patch that touch the same
previous line

why not we can choose to have a default cmdline and even usit as a complement
of the bootloader one
it's up to the dts maintainer to choose

..which is why the dts files should be added alphabetically instead of

The chance of having a valid generic command line that will work for
everyone with that hardware is fairly small, especially on more
generic systems that might have a regular distro installed on them.

this does not hurt anyone 99% of the people will overwrite you can just see as
a cmdline example
