Subject: [PATCH net-next v3 1/9] dt-bindings: net: mediatek-dwmac: fix unit in rx/tx delay property description
Date: Fri, 16 Oct 2026 12:31:05 +0200	[thread overview]
Message-ID: <20261016-dwmac-mediatek-mt8189-v3-1-25daf2bbcf35@collabora.com> (raw)
In-Reply-To: <20261016-dwmac-mediatek-mt8189-v3-0-25daf2bbcf35@collabora.com>

The "mediatek,rx-delay-ps" and "mediatek,tx-delay-ps" descriptions say
their values are in nanoseconds but their names with the "ps" suffix
suggest it is picoseconds.
They are in fact used in both driver and devicetree as picosecond.
So, modify the two properties unit description to fix their unit.

Fixes: 150b6adda6b1 ("net: dt-bindings: dwmac: Convert mediatek-dwmac to DT schema")
