Subject: [PATCH 0/2] i2c: i801: Use MMIO if available
Date: Wed, 12 Mar 2025 20:06:31 +0100	[thread overview]
Message-ID: <28ad9377-6d8a-4259-8cd4-7edaa00e26d7@gmail.com> (raw)

Newer versions of supported chips support MMIO in addition to legacy
PMIO register access. Probe the MMIO PCI BAR and use faster MMIO
register access if available.

Tested on N100 (Alder Lake-N).

This series is a rebased re-spin of a series submitted last October.
