Merge tag 'clk-for-linus-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Michael Turquette: "The bulk of the changes are updates and fixes to existing clk provider drivers, along with a pretty standard number of new drivers. The core recieved a small number of updates as well. Core changes of note: - removed CLK_IS_ROOT flag New clk provider drivers: - Renesas r8a7796 clock pulse generator / module standby and software reset - Allwinner sun8i H3 clock controller unit - AmLogic meson8b clock controller (rewritten) - AmLogic gxbb clock controller - support for some new ICs was added by simple changes to static data tables for chips sharing the same family Driver updates of note: - the Allwinner sunxi clock driver infrastucture was rewritten to comform to the state of the art at drivers/clk/sunxi-ng. The old implementation is still supported for backwards compatibility with the DT ABI" * tag 'clk-for-linus-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (162 commits) clk: Makefile: re-sort and clean up Revert "clk: gxbb: expose CLKID_MMC_PCLK" clk: samsung: Allow modular build of the Audio Subsystem CLKCON driver clk: samsung: make clk-s5pv210-audss explicitly non-modular clk: exynos5433: remove CLK_IGNORE_UNUSED flag from SPI clocks clk: oxnas: Add hardware dependencies clk: imx7d: do not set parent of ethernet time/ref clocks ARM: dt: sun8i: switch the H3 to the new CCU driver clk: sunxi-ng: h3: Fix Kconfig symbol typo clk: sunxi-ng: h3: Fix audio clock divider offset clk: sunxi-ng: Add H3 clocks clk: sunxi-ng: Add N-K-M-P factor clock clk: sunxi-ng: Add N-K-M Factor clock clk: sunxi-ng: Add N-M-factor clock support clk: sunxi-ng: Add N-K-factor clock support clk: sunxi-ng: Add M-P factor clock support clk: sunxi-ng: Add divider clk: sunxi-ng: Add phase clock support clk: sunxi-ng: Add mux clock support clk: sunxi-ng: Add gate clock support ...
