From mboxrd@z Thu Jan 1 00:00:00 1970 From: Masahiro Yamada Date: Sat, 8 Oct 2016 13:25:29 +0900 Subject: [U-Boot] [PATCH 7/9] ARM: uniphier: insert udelay() just before support_card_reset_deassert() In-Reply-To: <1475900731-10998-1-git-send-email-yamada.masahiro@socionext.com> References: <1475900731-10998-1-git-send-email-yamada.masahiro@socionext.com> Message-ID: <1475900731-10998-8-git-send-email-yamada.masahiro@socionext.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de As for LD11/LD20, we can no longer rely on the udelay() in the PLL init functions. udelay(200) is needed here to keep the ethernet device in the reset state for enough time. Anyway, 200 usec is quite short for humans, so nobody cares it.
