From c17435c56bb1feb7365ebffcfbe98baae50a0fb4 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Thu, 29 Sep 2016 12:05:00 +0300 Subject: [PATCH] clk: ti: add API for creating aliases automatically for simple clock types This API generates clock aliases automatically for simple clock types (fixed-clock, fixed-factor-clock), so that we don't need to add the data for these statically into tables. Shall be called from the SoC specific clock init.
