[PATCH 0/1] add support for the NAND clocks on Meson8b

[Martin Blumenstingl]

This adds support for the NAND clocks found in the Meson8b SoC.
The clocks consist of a simple gate, a divider and a mux. The mux
parents are not documented in the public S805 datasheet [0], so I
had to use a bit of math and take the vendor kernel as reference [1]
to find the actual parent clocks.
Some mux parents cannot be divided down without remainder to the
target clocks (as expected by the vendor NAND driver) these clocks
have the ROUND_CLOSEST flag set.

This is based on the "clk-meson" branch (e65ae3fb97b4 "dt-bindings:
clock: gxbb-clkc: Add GXL compatible variant")
