Hi Roger,
patches modifying the rockchip clock parts should have a subject like
clk: rockchip: .....
Same for the following patch

Why do you need to export the mac pll source selection?
I understand SCLK_MAC below, as you will want to select ext_gmac explicitly if
available. But otherwise, why would you need to explicitly select the pll
source?
The clock framework is intelligent enough that when you do a
clk_set_rate(sclk_mac, 50000000) for example that it will select the best pll
source + best divider to provide the most accurate frequency for this, so
there should be no need to handle the pll source manually.
