[PATCH 0/2] Add Altera timeout bridge driver

[Vyacheslav Yurkov via B4 Relay <devnull+V.Yurkov.EXT.bruker.com@kernel.org>]

This series adds support for the Altera timeout bridge IP. 

The timeout bridge connects an Avalon bus to the HPS and provides a
downstream address space for devices implemented in the FPGA. The
bridge also exposes status information and generates an interrupt when
a timeout occurs.

The driver registers the timeout bridge as a bus and allows child
devices behind the bridge to be described as the child nodes in the
device tree.

The latest bridge documentation (as of October 2026):
