Pull Amlogic clk driver updates from Jerome Brunet:

 * Expose more clock gate on meson8 (SAR ADC, RNG, USB, SDIO, ETH)
 * Add new compatible to the meson8 clock controller for meson8b
 * Add missing parents to gxbb clk81

* tag 'meson-clk-for-4.13-2' of git://github.com/BayLibre/clk-meson:
  clk: meson: gxbb: add all clk81 parents
  clk: meson: meson8b: add compatibles for Meson8 and Meson8m2
  clk: meson8b: export the ethernet gate clock
  clk: meson8b: export the USB clocks
  clk: meson8b: export the gate clock for the HW random number generator
  clk: meson8b: export the SDIO clock
  clk: meson8b: export the SAR ADC clocks
