Log:
MFC r357250, r363926-r363927
r357250 (by ganbold@):
Add USB3 related clock definitions for Rockchip RK3328 SoC.
Reviewed by: manu
r363926:
Add flag for SYSCON-controlled clocks on Rockhip platform
Ethernet clocks on RK3328 are controlled by SYSCON registers, so add
RK_CLK_COMPOSITE_GRF flag to indicate that clock node should access grf
registers instead of CRU's
