  clk: Move __clk_{get,put}() into private clk.h API
  clk: sunxi: Use CLK_IS_CRITICAL flag for critical clks
  arch: Remove clkdev.h asm-generic from Kbuild
  clk: Prepare to remove asm-generic/clkdev.h
  blackfin: Use generic clkdev.h header

* clk-debugfs-fixes:
  clk: Simplify debugfs registration
  clk: Fix debugfs_create_*() usage
  clk: Show symbolic clock flags in debugfs
  clk: Improve flags doc for of_clk_detect_critical()

* clk-renesas:
  clk: renesas: r8a7796: Add FDP clock
  clk: renesas: cpg-mssr: Keep wakeup sources active during system suspend
  clk: renesas: mstp: Keep wakeup sources active during system suspend
  clk: renesas: r8a77970: Add LVDS clock

* clk-meson:
  clk: meson-axg: fix potential NULL dereference in axg_clkc_probe()
  clk: meson-axg: make local symbol axg_gp0_params_table static
  clk: meson-axg: fix return value check in axg_clkc_probe()
  clk: meson: mpll: use 64-bit maths in params_from_rate
  clk: meson-axg: add clock controller drivers
  clk: meson-axg: add clocks dt-bindings required header
  dt-bindings: clock: add compatible variant for the Meson-AXG
  clk: meson: make the spinlock naming more specific
  clk: meson: gxbb: remove IGNORE_UNUSED from mmc clocks
  clk: meson: gxbb: fix wrong clock for SARADC/SANA
