From: Adriana Reus adriana.reus@nxp.com
[ Upstream commit edc5a8e754aba9c6eaeddd18cb1e72462f99b16c ]
The parent of OCRAM_CLK should be axi_main_root_clk and not axi_post_div.
before:
axi_src 1 1 332307692 0 0 axi_cg 1 1 332307692 0 0 axi_pre_div 1 1 332307692 0 0 axi_post_div 1 1 332307692 0 0 ocram_clk 0 0 332307692 0 0 main_axi_root_clk 1 1 332307692 0 0
after:
axi_src 1 1 332307692 0 0 axi_cg 1 1 332307692 0 0 axi_pre_div 1 1 332307692 0 0 axi_post_div 1 1 332307692 0 0 main_axi_root_clk 1 1 332307692 0 0 ocram_clk 0 0 332307692 0 0
