Sorry about that, missed out doing that posting this time.

-- clock-names: the following clocks are required:
+- clock-names: these vary based on the DSI version. For DSI6G:
* "bus_clk"
* "byte_clk"
+ * "byte_clk_src
This sounds like the parent of byte_clk. Is that really a clock within
the block?
byte_clk_src isn't in the block, but byte_clk_src's parent is one of
the PLLs in this block. We take this clock so that we can re-parent
it to an appropriate PLL. The decision of what PLL to choose needs to
be done by the DSI block's driver.
* "core_clk"
* "core_mmss_clk"
* "iface_clk"
* "mdp_core_clk"
* "pixel_clk"
+ * "pixel_clk_src"
+ For DSIv2, we need a few more:
What is the overall order of clocks? As listed?
Order in which the driver does clk_get? It uses the clock
name to get each one individually, so the order doesn't matter
as such.
I don't think it the order of clk_get in the driver is the same
as what's been listed here. I can fix it if that's the norm.
Thanks,
