cpu_psci_cpu_die() is called in the context of the dying CPU, which
will no longer be online or tracked by RCU. It is therefore not generally

How about a different interface for those cpufreq drivers?

The i.MX8M Nano has supports the MICFIL digital interface.

The driver exists for the Enhanced Asynchronous Sample Rate Converter

On the vendor kernel, they put this on a spba-bus for SDMA support.
Add the node for the spba-bus with the easrc node inside.

This series adds support for the ELAN eKTF2132 touchscreen controller to
the existing ektf2127 driver. It is similar to the eKTF2127, but it uses
a different packet type and format to report touch events.
My understanding of the packet format is based on the Kobo Arua vendor
kernel:

The Kobo Aura has an eKTF2132 touchscreen controller.
Although the vendor kernel toggles a reset pin (GPIO5-12) during the
startup sequence, the touchscreen works without it.

I actually used AF_PACKET sockets to transport data directly over LAPB

LAPB doesn't need anything from layer 3. I
