The orignal commit 3263e09d287fbaa8a9424b5e69396599a3bbd518 (ARM: shmobile: Initial r8a73a4 SoC support V3) put MP clock parent as EXTAL2, but its code was removed on DIV6 clock support commit. This patch makes it consistent. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
