Subject[PATCH v1] clk: Add enable-state column to clk summary
Date
Add "enable state" column to the clk summary. It's handy to know actual
hardware state of all clocks for debugging purposes. In conjunction with
clk_ignore_unused, this tells us what unused clocks are left on after
bootloader without disabling the clocks. It's also s useful debugging
information for cases where firmware touches clocks.
