Subject: [PATCH 1/3] net: phy: smsc: add proper reset flags for LAN8710A
Date: Wed, 9 Jul 2025 15:32:20 +0200 [thread overview]
Message-ID: <20250709133222.48802-2-buday.csaba@prolan.hu> (raw)
In-Reply-To: <20250709133222.48802-1-buday.csaba@prolan.hu>
According to the LAN8710A datasheet (Rev. B, section 3.8.5.1), a hardware
reset is required after power-on, and the reference clock (REF_CLK) must be
established before asserting reset.
