From c8edb316b9bb6149193436dfbd240994733e27be Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Fri, 14 Jun 2019 10:46:06 -0700 Subject: [PATCH] clk: Do a DT parent lookup even when index < 0 We want to allow the parent lookup to happen even if the index is some value less than 0. This may be the case if a clk provider only specifies the .name member to match a string in the "clock-names" DT property. We shouldn't require that the index be >= 0 to make this use case work.
