[PATCH v4 00/13] Add RSPI support for RZ/T2H and RZ/N2H

[Cosmin Tanislav]

V4:
 * remove conditional minItems: 2 and maxItems: 3 for clocks property
   since it is already set to that
 * remove renesas,r9a09g087-rspi check since it implies
   renesas,r9a09g077-rspi
 * replace contains: enum: with contains: const: since there's only one
   compatible to be checked against

V3:
 * no changes

V2:
 * fix missing unwind goto quit_resets
 * add resets: false and reset-names: false

Cosmin Tanislav (13):
  spi: rzv2h-rspi: make resets optional
  spi: rzv2h-rspi: make FIFO size chip-specific
  spi: rzv2h-rspi: make clocks chip-specific
  spi: rzv2h-rspi: move register writes out of rzv2h_rspi_setup_clock()
  spi: rzv2h-rspi: avoid recomputing transfer frequency
  spi: rzv2h-rspi: make transfer clock rate finding chip-specific
  spi: rzv2h-rspi: add support for using PCLK for transfer clock
  spi: rzv2h-rspi: add support for variable transfer clock
  spi: rzv2h-rspi: add support for loopback mode
  dt-bindings: spi: renesas,rzv2h-rspi: document RZ/T2H and RZ/N2H
  spi: rzv2h-rspi: add support for RZ/T2H and RZ/N2H
  arm64: dts: renesas: r9a09g077: Add SPIs support
  arm64: dts: renesas: r9a09g087: Add SPIs support
