Hello,
currently I try to migrate the friendlyARM U-Boot from
https://github.com/friendlyarm/u-boot (v2016.01, for boards with s5p4418
SOC) to the current (official) U-Boot version.
Now I have some trouble migrating to Video DM. "CONFIG_SPLASH_SCREEN" is
used and therefore an appropriate screen is displayed. With the updated
code this is not working anymore because the probe-function is not
called (the bind-function is called). My new driver declaration is as
following:
U_BOOT_DRIVER(nexell_display) = {
.name = "nexell-display",
.id = UCLASS_VIDEO,
.of_match = nx_display_ids,
.bind = nx_display_bind,
.probe = nx_display_probe,
.priv_auto_alloc_size = sizeof(struct nx_display_dev),
};
In "doc/driver-model/README.txt" the following is stated:
...
2. Activation/probe
When a device needs to be used, U-Boot activates it, by following these
steps (see device_probe()):
...
But if "CONFIG_SPLASH_SCREEN" is defined then the video device "needs to
be used" and the probe-function should be called? Or do I have to call
the probe-function by my self? If so how?
Regards
Stefan
