From 610a5d83010eaf02a857321092cf0cd02178bee7 Mon Sep 17 00:00:00 2001 From: Rajan Vaja <rajan.vaja@xilinx.com> Date: Mon, 28 Jun 2021 00:01:19 -0700 Subject: clk: zynqmp: Use firmware specific common clock flags Currently firmware passes CCF specific flags to ZynqMP clock driver. So firmware needs to be updated if CCF flags are changed. The firmware should have its own 'flag number space' that is distinct from the common clk framework's 'flag number space'. So define and use ZynqMP specific common clock flags instead of using CCF flags.
