Previously the code would always run into the loop limitation > of 1000 iterations because the flag is never set when turning the PLLs off. > > Signed-off-by: Julien Langer > Signed-off-by: Anders Larsen > Cc: Andrew Victor > Cc: Russell King During suspend we set the MULA and MULB bits to 0 to disable the PLL's. When disabled, the PLLs will never "lock".
