Geert Uytterhoeven 7b39e985cf ARM: dts: r8a7792: Correct Z clock
Unlike other R-Car Gen2 SoCs with Cortex-A15 CPU cores, R-Car V2H does
not have a programmable Z clock (Cortex-A15 CPU core clock), but uses a
fixed divider.
This is similar to the Z2 clock (Cortex-A7 CPU core clock) on R-Car E2.

Hence:
  - Remove the Z clock output from the cpg_clocks node, as this implied
    a programmable clock,
  - Add the Z clock as a fixed factor clock,
  - Let the first CPU node point to the new Z clock,
  - Remove the Z clock index from the bindings (this definition was used
    by r8a7792.dtsi only, and was not a contract between DT and driver).

Geert Uytterhoeven 90dce5428a ARM: dts: r8a7792: Add INTC-SYS clock to device tree
Link the ARM GIC to the INTC-SYS module clock, and add it to the "always
on" PM Domain, so it can be power managed using that clock.

Note that currently the GIC-400 driver doesn't support module clocks nor
Runtime PM, so this must be handled as a critical clock.

Sergei Shtylyov e0c3f92a08 ARM: dts: r8a7792: remove ADSP clock
Simon Horman told me that R8A7792 has ADSP clock based on an incorrect
table in the most recent R-Car gen2 manual. But when I received that manual
I discovered that this is false: R8A7792 is the only Gen 2 SoC that doesn't
have ADSP at all.  Accordingly remove the ADSP clock from DT for the
r8a7792.
