From 66e3efebbcfe2627154d81d6a3c172b337396daf Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 8 Oct 2016 13:25:29 +0900 Subject: [PATCH] ARM: uniphier: insert udelay() just before support_card_reset_deassert() 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.
