Nope. Accessing device drivers (enabled in the device-tree) is possible
in the section: device_initcall() and *NOT* in the coredevice_initcall()
Anyway I was wondering if looking for a node in the device-tree, it will
be possible to change the status of that node.
in DTS I have
but I need to set the status to "okay" later on the device_initcall() time.
Iterating in the device tree using for_each_node_by_name_from() does not
show any node like hdmi, but using the same function to look for any
"display-timing" section it works.
Why? Where I have to look on to change the status of the device driver
node &hdmi and &ldb?
I see a lot of __fixup() functions but I do not understand it correctly.
Like to change the phandle of the native-mode too..
