Subject: [PATCH v3 1/3] dt-bindings: i3c: snps: Add Altera Agilex5 SoC compatible

From: Adrian Ng Ho Yin <adrianhoyin.ng@...era.com>

Add the "altr,agilex5-dw-i3c-master" compatible string to the
Synopsys DesignWare I3C master binding. This allow Agilex5 to
use the generic DW I3C master controller while applying any
required platform-specific quirks.
