Re: [alsa-devel] r8a7790 only has audio when clock is forced on

Hi Ben, Violeta

     reg =   <0 0xec500000 0 0x1000>, /* SCU */
             <0 0xec5a0000 0 0x100>,  /* ADG */
             <0 0xec540000 0 0x1000>, /* SSIU */
             <0 0xec541000 0 0x1280>; /* SSI */
     clocks = <&mstp10_clks R8A7790_CLK_SSI>,

I don't think we have this one here.

Indeed. Adding it fixed our issue.

Phew, nice ! Sorry for my poor English which causes delay solution.

• SSI(ALL) is called via pm_runtime_xxx() from sound driver
• SRC(ALL) is called as parent clock of SRCn clocks

See, this is why I /hate/ the implicit clock management. This is another case where we're getting bitten by it.

I troubled about this ALL bit too, then, it become current style.

One reason was that this driver is supporting Gen1 sound too. But, this SRC(ALL) didn't exist on Gen1..
