From 0316c018c5a84d4e0b43123057adada3cddb3e00 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 20 Jul 2018 17:37:35 +0900 Subject: [PATCH] clk: uniphier: add NAND 200MHz clock The Denali NAND controller IP needs three clocks: - clk: controller core clock - clk_x: bus interface clock - ecc_clk: clock at which ECC circuitry is run Currently, only the first one (50MHz) is provided. The rest of the two clock ports must be connected to the 200MHz clock line. Add this.
