Hi Mark,

	Now I want to replace the original devm_clk_get API in the
driver with devm_clk_bulk_get_all API, which can achieve compatibility,
but it seems that it is not good for other ip with only one clock, so I
want to ask about that can I replace it? Or define that inside jh7110?

Best regards,
William
