Subject: [PATCH] rockchip: clk: rk3399: accept all assigned-clocks from the
'cru'-node
The RK3399 CRU-node assigns rates to a number of clocks that are not
implemented in the RK3399 clock-driver (but which have been
sufficiently initialised from rkclk_init()): for these clocks, we
simply ignore the set_rate() operation and return 0 to signal success.
