Hi SH ML, ALSA ML
We have below sound drivers in upstream kernel. But, these are not used from upstreamed board. And, these are for very old SoC. I guess Renesas doesn't/can't support these SoC/board anymore. Can we remove these sound drivers ? Because maintenance cost for these is not zero...
- ${LINUX}/sound/soc/sh/ssi.c - SH7760/SH7780 - CONFIG_SND_SOC_SH4_SSI
- ${LINUX}/linux/sound/soc/sh/hac.c - SH7760/SH7780 - CONFIG_SND_SOC_SH4_HAC
- ${LINUX}/sound/soc/sh/sh7760-ac97.c - SH7760 - CONFIG_SND_SH7760_AC97
- ${LINUX}/sound/soc/sh/dma-sh7760.c - SH7760 - CONFIG_SND_SOC_PCM_SH7760
- ${LINUX}/sound/soc/sh/siu_dai.c *1 ${LINUX}/sound/soc/sh/siu_pcm.c ${LINUX}/sound/soc/sh/siu.h - SH7343, SH7722 - CONFIG_SND_SOC_SH4_SIU
- ${LINUX}/sound/soc/sh/migor.c *2 - SH7722 - CONFIG_SND_SIU_MIGOR
*1 it is registered from ${LINUX}/arch/sh/kernel/cpu/sh4a/setup-sh7722.c but, no one enabled CONFIG_SND_SOC_SH4_SIU in defconfig
*2 it uses *1, but no one enabled CONFIG_SND_SIU_MIGOR
