| | | | | | | | | | | | This function is used from more places than just __init code. Removing __init silences a section mismatch warning here.

* clk: Convert to using %pOF instead of full_nameRob Herring2017-07-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

* clk: mediatek: fixed static checker warning in clk_cpumux_get_parent callSean Wang2017-07-171-4/+0
| | | | | | | | | | | | Fixed the signedness bug returning '(-22)' on the return type as u8 with removing the sanity checker in clk_cpumux_get_parent() since clk_cpumux_set_parent() always ensures validity in clk_cpumux_get_parent() got called.

* clk: mediatek: add missing cpu mux causing Mediatek cpufreq can't workSean Wang2017-06-191-0/+120
This patch adds CPU multiplexer clocks which are essential for Mediatek cpufreq driver. It would use the CPU clock multiplexer to switch to the intermediate clock source temporarily and then wait for the primary clock changing getting stable.
