From 7d75254b3d0dcc3231eca11c4c5143972ce25232 Mon Sep 17 00:00:00 2001 From: Kotaro Hayashi Date: Mon, 19 Dec 2016 11:14:04 +0900 Subject: [PATCH] ARM: uniphier: fix delay fixup code in LD11 UMC init The ddrphy_shift_rof_hws() never writes back the shifted delay value to the register, which makes this function non-effective.
