Why don't you put each entry into a single line instead?

Even if it gets larger than 80 columns, it would be easier to read.

I thought about it, but came to the conclusion that it is better to observe
the kernel rules.

Do you mean checkpatch complaint?

Then try to make checkpatch happy with other clock file such as
arch/arm/mach-imx/clk-imx6q.

The result will be unreadable :-)

As another solution we can use macros, something like this:

#define IMXCLK_MUX(id, name, reg, off, sz, arr)	\
	clk[id] = imx_clk_mux(name, reg, off, sz, arr, ARRAY_SIZE(arr))

...
	IMXCLK_MUX(IMX1_CLK_PREM, "prem", CCM_CSCR, 16, 1, prem_sel_clks);

Please don't do that. We have i.MX specific wrapper functions. Wrapping
these again with macros doesn't improve the situation. I'm with Fabio
here, I would prefer the functions in a single line.

OK. Shawn, if no objections to parts 1 and 2, I would like them to be applied.

+- reg: Address and length of the register set.
+- interrupts: Should contain CCM interrupt.
