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.

Please add them alphabetically, so before smdk.

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
just appended to the list.

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.

we need to drop this \

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