Subject: [PATCH v4 10/12] arm64: dts: rockchip: rk3588s-nanopi-r6: add comment to gmac phy-mode
Date: Fri, 17 Jul 2026 09:23:08 +0200 [thread overview]
Message-ID: <20260717-nanopi-m6-v4-10-b31391a72e41@gmail.com> (raw)
In-Reply-To: <20260717-nanopi-m6-v4-0-b31391a72e41@gmail.com>
From: Joachim Eastwood <joachim.eastwood@gmail.com>
Add comment to explain rgmii-rxid phy-mode usage. Note that the actual
delay in ns is not known. The tx_delay value of 0x42 comes from vendor
DT.
