It's not clear what kernel this series is meant to apply to. It doesn't apply cleanly to v4.1-rc2 (the version stated for v5) or the current -rc (v4.1-rc5) it also doesn't apply cleanly to linus/master or linux-next. If the series doesn't apply to Linus tree, please state clearly in the changelog what tree it should apply to as well as any dependncies. Also, this version is missing patch 1 from the v6 series, which adds the Kconfig/defconfig changes. Without that patch, nothing in this series is even compiled (clk driver or DTS files.) So my recommendation, since the clock driver is very close to being merged: Please create a v9 series with *only* the patches that are not already queued up on the clk tree[1]. That should be patches 1-3 and 7 of this series, plus patch 1 from v6. That series should apply cleanly to v4.1-rc1 (or a newer -rc if there are dependencies.) In the changelog to that series, state the version that it applies to, and also state that it depends on the clk-next branch where the clock maintainers have queued up the driver[1]. Then all that's left is to collect an ack from a DT maintainer, and these can be queued up via the arm-soc tree. FWIW, I've boot tested patches 1-3 and 7 of this series, plus patch 1 from v6 combined with the clk-next-hi6220 branch[1] on my board (which uses ATF + mainline u-boot) and all 8 A53 cores are coming up, so feel free to add: Tested-by: Kevin Hilman to your v9 series.
