[PATCH 0/2] Document Media Controller IOCTL number assignments

Posted by Sakari Ailus 6 months, 3 weeks ago

Hello all,

The Media Controller uses IOCTL numbers with '|' type up to 0x81 but the
range from 0x80 upwards is documented to belong to samples. The samples,
however, are not currently using these values. Solve the problem by
bumping the top of the MC range and the samples allocation by 0x10.

Some sample code in samples/rust/rust_misc_device.rs also uses MC IOCTL
numbers below the current limit 0x80, it'd be nice to address that as well
as align with the changes in this patch.
