BockW had used SRU before, but it was pass through mode. This means it is same as SSI. And BockW "platform base" code was removed from upstream code. It is now supported via DT, but it doesn't use SRU. More detail, r8a7778.dtsi has "rcar_sound,src" entry, but no-one is using this feature today. SRU probing has no relation to this removing. This means there is no effect for DT compatibility, no issues on upstream kernel. Gen2 SRC was created from Gen1 SRU, these are similar but not same IP. Keeping Gen1 SRU in current driver is a little bit difficult, and no-one is using it today. Gen1 sound is still supported via SSI. Gen1 SRU support will be removed in the next kernel version. This patch announces it.
