From e3f8bc8c6ecd0bcb7b4d413332b068ebbbcc31ee Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Tue, 16 Sep 2014 09:07:11 -0300 Subject: [PATCH] [media] smiapp-pll: Unify OP and VT PLL structs Uniform representation for VT and OP clocks. This is preparation for calculating the VT clocks using the OP clock code.
