Merge tag 'amlogic-dt64-2' of git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic into next/dt64
Amlogic 64-bit DT updates for v4.14, round 2
- clock updates w/dependencies on clock tree
- GPIO names updates
* tag 'amlogic-dt64-2' of git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic:
ARM64: dts: meson-gxl-libretech-cc: Add GPIO lines names
ARM64: dts: meson-gx: Add AO CEC nodes
ARM64: dts: meson-gx: update AO clkc to new bindings
dt-bindings: clock: gxbb-aoclk: Add CEC 32k clock
clk: meson: gxbb: Add sd_emmc clk0 clkids
clk: meson-gxbb: expose almost every clock in the bindings
clk: meson8b: expose every clock in the bindings
clk: meson: gxbb: fix protection against undefined clks
clk: meson: meson8b: fix protection against undefined clks
dt-bindings: clock: meson8b: describe the embedded reset controller
