From e3107d159c180698bd45511afb76e9ab8f9957fb Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 14 Nov 2019 12:57:28 -0700 Subject: [PATCH] arm: pxa: Drop pxa_wait_ticks() This function has a similar name to the common wait_ticks(). It is only used in one place and seems small enough to drop. Inline it.
