Merge series "Add RZ/G2L Sound support" from Biju Das <biju.das.jz@bp.renesas.com>: 

This patch series aims to add ASoC support on RZ/G2L SoC's.

It is based on the work done by Chris Brandt for RZ/A ASoC driver.

Biju Das (8):
  ASoC: dt-bindings: Document RZ/G2L bindings
  sound: soc: sh: Add RZ/G2L SSIF-2 driver
  arm64: dts: renesas: r9a07g044: Add external audio clock nodes
  arm64: dts: renesas: r9a07g044: Add SSI support
  arm64: defconfig: Enable ASoC sound support for RZ/G2L SoC
  ASoC: dt-bindings: sound: renesas,rz-ssi: Document DMA support
  sound: sh: rz-ssi: Add SSI DMAC support
  arm64: dts: renesas: r9a07g044: Add SSI DMA support
