Hello, we are looking at up-streaming some of the work we have
done on the tegra2 and tegra3 automotive devices. The automotive
grade devices are close the commercial parts so we would like to
discuss the core changes before submitting.
The changes are mostly with things like the clock setup and a
few peripheral quirks (IIRC these are mostly MMC).
We are proposing to change the device-tree properties for the root
node and any other affected devices from "nvidia,tegraXX" to a new
"nvidia,tegraXXa". We would welcome discussion on whether to update
all the devices at the start
An example of tegra30a.dtsi:
#include "tegra30.dtsi"
/ {
compatible = "nvidia,tegra30a";
clock@60006000 {
compatible = "nvidia,tegra30a-car";
};
}
We don't think the changes are big enough to warrant their own
Kconfig/defconfig updates.
What kind of changes do you have? Tegra30a would point to a separate SoC
revision of Tegra3 the existence of which I'm not aware of. If you can
show some of the changes it would be easier to say how the system should
be specified.
Thanks,
Mikko
