[PATCH v2 0/2] i3c: dw: Document optional core reset and drop redundant name
From: Shubham Patil
Date: Mon Jul 20 2026 - 03:35:32 EST
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.
