As described in [1], the "clocks" property contains "a phandle to the clock device node, an index selecting between gated clocks (0) and other clocks (1), and an index specifying the clock to use." The current version of the clock driver, unlike the kernel, is currently able to properly handle nodes with "clocks" properties with an index set to 0.
This patch is preparatory for future developments that require the use of the DSI clock.
