Subject: [PATCH v2 0/2] i3c: dw: Document optional core reset and drop redundant name
Date: Mon, 20 Jul 2026 13:05:08 +0530	[thread overview]
Message-ID: <20260720073510.1869623-1-shubhamsanjay.patil@amd.com> (raw)

This series documents the optional core reset for the Synopsys
DesignWare I3C master and updates the driver to match the binding.
The DesignWare I3C master IP has a single core reset input. The
binding never documented this reset, and the driver looked it up by
the "core_rst" name even though a name is redundant for a single
reset line.

This series addresses both:
  - Patch 1 documents the optional 'resets' property in the binding.
    The reset is kept optional because the reset line is
    integration-specific.
  - Patch 2 removes the "core_rst" reset name from the driver and
    looks the reset up by passing NULL, since the name is redundant
    for a single reset.

Changes in v2:
- Updated commit description for binding patch
- Dropped reset-names from the binding
- Added driver patch to remove redundant reset name

Note:
The DesignWare I3C driver support was added by
commit 1dd728f5d4d4 ("i3c: master: Add driver for Synopsys DesignWare IP").

The original Synopsys DesignWare I3C binding was added by
commit 116e246a8bcd ("dt-binding: i3c: Document Synopsys DesignWare I3C"),
but it did not document the optional core reset.
