This patch series aims to add RZ/G2L sound support by adding
SSIF and audio clock nodes to SoC dtsi.
Currently SSI interrupt support is added in SoC dtsi, later will add DMA
support, once DMA patches accepted in mainline.
This patches are tested(audio playback/record) with renesas-devel and is based upon[1] & [2]

Add external audio clocks nodes to RZ/G2L (a.k.a R9A07G044) SoC DTSI.
The external audio clocks are configured as 0 Hz fixed frequency clocks by
default. Boards that provide audio clocks should override them.
