I agree this is a reasonable move. But while you simplify the interface
of clk_register(), why not making a further step to simplify the
following interfaces simple too?

struct clk *clk_register_fixed_rate(struct device *dev, const char *name,
const char *parent_name, unsigned long flags,
unsigned long fixed_rate);
struct clk *clk_register_gate(struct device *dev, const char *name,
const char *parent_name, unsigned long flags,
void __iomem *reg, u8 bit_idx,
u8 clk_gate_flags, spinlock_t *lock);
struct clk *clk_register_divider(struct device *dev, const char *name,
const char *parent_name, unsigned long flags,
void __iomem *reg, u8 shift, u8 width,
u8 clk_divider_flags, spinlock_t *lock);
struct clk *clk_register_mux(struct device *dev, const char *name,
char **parent_names, u8 num_parents, unsigned long flags,
void __iomem *reg, u8 shift, u8 width,
u8 clk_mux_flags, spinlock_t *lock);

Otherwise,
