The Amlogic G12B SoC is very similar with the G12A SoC, sharing
most of the features and architecture.
G12B clock tree is very close, the main differences are :
- SYS_PLL is used for the second cluster (otherwise used fir the first on G12a)
- SYS_PLL1 is used for the first cluster (instead of SYS_PLL on G12a)
- A duplicate CPU tree is added for the second cluster
- G12A has additional clocks like for CSI an other components, not handled yet
Dependencies :
- Patch 1, 3 : None
- Patch 2 : Depends on Guillaume's Temperature sensor Clock patches at [1]
This patchset is a spinoff of the v2 Odroid-N2 megapatchset at [2]
Changes since original pathset :
- Added missing sys1_pll div16, cpub div16 and cpub atb/axi/ahb/trace clocks
- Rewrote "This patch .." in commit messages

The subject is wrong, it should be "clk: meson: add support for Amlogic G12B"

And I forgot Martins reviews...
It should still apply to patch 1, patch 2 has changed with new clocks.

You probably want to change the series title as well, s/G12A/G12B maybe ?
