Subject: [PATCH 107/247] clk: at91: sama7g5: remove mck0 from parent list of
|
|
other clocks
|
|
|
|
MCK0 is changed at runtime by DVFS. Due to this, since not all IPs
|
|
are glitch free aware at MCK0 changes, remove MCK0 from parent list
|
|
of other clocks (e.g. generic clock, programmable/system clock, MCKX).
