This series adds CRG driver for Hi3798MV100 SoC.
v2: move bindings to a separate patch
v3: fix bindings commit message, reorganize patches
v4: add ethernet and gpu clocks
v5: add complex clock
v6: migrate devm api

This looks costly and sometimes incorrect. The use of devm_ APIs means
that a driver is bound to the device. When the driver is unbound the
devm APIs cleanup and remove resources allocated. If you're simply
finding the device associated with a device node you can't tell if the
device is bound to a driver or not. So you should stop passing a
device_node pointer to these functions and switch them to a struct
device, or keep the device_node because you don't have a struct device
that's bound to a driver in the caller, in which case you can't use devm
APIs.

Some general comments. Typically we link to previous rounds with lore
links like
https://lore.kernel.org/r/message.id.of.previous.cover.letter
and also generate patches with `git format-patch --base` so we know what
baseline kernel version was used to develop on. And, please send your
emails To: something/somebody. Right now the To: header is empty, so it
looks like spam.

Hi David,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on clk/clk-next]
[also build test ERROR on linus/master v6.3-rc3 next-20230322]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
