From a4b10c088c4f6ef2e2bba33e8cfea369bcbbce44 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 21 Jan 2016 19:44:00 -0700 Subject: dm: clk: Add a simple version of clk_get_by_index() This function adds quite a bit of code to SPL and we probably don't need all the features in SPL. Add a simple version (for SPL only) to save space.
