- Stop using clock-output-names in ST clk drivers

* clk-st:
  dt-bindings: clock: st: clkgen-fsyn: add new introduced compatible
  clk: st: clkgen-fsyn: embed soc clock outputs within compatible data
  dt-bindings: clock: st: clkgen-pll: add new introduced compatible
  clk: st: clkgen-pll: embed soc clock outputs within compatible data
  dt-bindings: clock: st: flexgen: add new introduced compatible
  clk: st: flexgen: embed soc clock outputs within compatible data
  clk: st: clkgen-pll: remove unused variable of struct clkgen_pll

* clk-si:
  clk: si5341: Add sysfs properties to allow checking/resetting device faults
  clk: si5341: Add silabs,iovdd-33 property
  clk: si5341: Add silabs,xaxb-ext-clk property
  clk: si5341: Allow different output VDD_SEL values
  clk: si5341: Update initialization magic
  clk: si5341: Check for input clock presence and PLL lock on startup
  clk: si5341: Avoid divide errors due to bogus register contents
  clk: si5341: Wait for DEVICE_READY on startup
  dt-bindings: clock: clk-si5341: Add new attributes

* clk-hisilicon:
  clk: hisilicon: Add clock driver for hi3559A SoC
  dt-bindings: Document the hi3559a clock bindings
