This might be improved in the future by using platform_device_id,
or by introducing some flags from platform_data, or when registering
the pwm devices.

Do you really need "pwm"?  I think NULL should do the job.

IMHO these should go into a seperate patch and preferably dynamically
allocated.

If you do this, can you please use SOC_IMX21 and SOC_IMX25?  Or maybe
even def_bool y?

Wouldn?t  "if (!cpu_is_mx1() && !cpu_is_mx21())" work here and make
the if statement simpler?

Yes, but less future proof.  (Assume the next generation SoC is
different ...)

there are already lines

	_REGISTER_CLOCK("mxc_pwm.0", "pwm", pwm1_clk)
	_REGISTER_CLOCK("mxc_pwm.1", "pwm", pwm2_clk)

further up in the list. I guess your definition is better, so can you
please remove the existing ones?

You can shorten this a bit:
	imx_mxc_pwm_data_entry(MX53, 0, 1, SZ_16K)
	imx_mxc_pwm_data_entry(MX53, 1, 2, SZ_16K)

I don't care much, but Sascha considers this better.
