Subject: [U-Boot] [PATCH 1/2] mx6cuboxi: Fix the delay for the AR8035 PHY
Date: Mon, 4 Jan 2016 14:36:17 -0200 [thread overview]
Message-ID: <1451925378-14121-1-git-send-email-festevam@gmail.com> (raw)
From: Fabio Estevam <fabio.estevam@nxp.com>
As per the AR8035 datasheet:
"For a reliable power on reset, suggest to keep asserting the reset
low long enough (10ms) to ensure the clock is stable and clock-to-reset
1ms requirement is satisfied."
So do as suggested and keep the reset low for 10ms.
