Currently SND_SOC_JZ4740_CODEC depends on SOC_JZ4740 but SOC_JZ4740 is not
defined in any Kconfig. Thus the codec driver will not be built when select
"Build all ASoC CODEC drivers".
(Unless it is selected by SND_JZ4740_SOC_QI_LB60).
Remove the dependency with SOC_JZ4740, then this code driver can be built when
select "Build all ASoC CODEC drivers".

Just checking the code in cs42l51_fill_cache():
The cache pointer points to codec->reg_cache + 1.
I think it is because CS42L51_FIRSTREG is 0x01,
so codec->reg_cache[0] is not used here.

Then we read CS42L51_NUMREGS bytes to cache.
So we need reg_cache_size to be CS42L51_NUMREGS + 1.

Replace the manual register restore mechanism in cs4270.c and call the
generic snd_soc_cache_sync() handler instead.

This factors code out in favour of core facilities and also fixes a
bus confusion that is most probably caused by intermixing i2c-regmap
functions and i2c_smbus_* accessors.

According to the datasheet:
The BIT[5:4] of ADC Control Register 2 is to control the word width.
        00 = 25 Bits
        01 = 20 Bits
        10 = 16 Bits
        11 = Invalid

Thus, the AD1836_ADC_WORD_OFFSET should be defined as 4.

codec->hw_write is broken now, convert codec->hw_write to snd_soc_write.

The hardware has 2 banks of registers sharing a section in I2C register space.
The 1st bank is the primary one and is cached.
The 2nd bank is for loading coefficients only and they do not need cache.
These coefficients registers are therefore direct writes.
Thus we set cache_bypass flag to deal with this before calling snd_soc_write.
