right justified and aligned with preceding please. While adding new
code to a existing driver it is a good idea to conform to existing
style
OK.

so if another version has this feature we would do:
if (jzdma->version == ID_JZ4770) ||
if (jzdma->version == ID_JZXXXX))
and so on.. why not add a value, clk_enable in the description and use
that. For each controller it is set to true or false
I agree with what you said in your other answers.
However here I still need to check the "version", because on JZ4725B
and JZ4770+
the way to start/stop each DMA channel's clock is different, so I can't
use a boolean.
