From bcc5fd49a0fda5abc22057f65b318788ccb5d2ad Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Mon, 15 Sep 2014 18:15:53 +0200 Subject: clk: at91: add a driver for the h32mx clock Newer SoCs have two different AHB interconnect. The AHB 32 bits Matrix interconnect (h32mx) has a clock that can be setup at the half of the h64mx clock (which is mck). The h32mx clock can not exceed 90 MHz.
