commit 8af6c521cc236534093f9e744cfa004314bfe5ae upstream.
Currently each SSI unit 's busif mode/adinr/dalign address is registered by: (in busif4 case) RSND_GEN_M_REG(SSI_BUSIF4_MODE, 0x500, 0x80) RSND_GEN_M_REG(SSI_BUSIF4_ADINR,0x504, 0x80) RSND_GEN_M_REG(SSI_BUSIF4_DALIGN, 0x508, 0x80)
But according to user manual 41.1.4 Register Configuration ssi9 4/5/6/7 busif mode/adinr/dalign register address ( SSI9-[4/5/6/7]_BUSIF_[MODE/ADINR/DALIGN] ) are out of this rule.
This patch registers ssi9 4/5/6/7 mode/adinr/dalign register as single register, and access these registers in case of SSI9 BUSIF 4/5/6/7.
