[PATCH] ASoC: cs35l41: Fix link problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Can't link I2C and SPI to the same binary, better
to move CS35L41 to 3 modules approach.
And instead of exposing cs35l41_reg, volatile_reg,
readable_reg and precious_reg arrays, move
cs35l41_regmap_i2c/spi to new module and expose it.
