The config option SND_FSI_AK4642 selects SND_SOC_AK464 which in turn
enables the compilation of ak4642.c - however this codec uses I2C to
communicate with the HW.
Consequently when I2C is not set, the compilation fails [1]
This patch fixes this issues.

I'd have thought a depends was more appropriate. Arguably you want to
depend on the SH I2C driver since the driver is useless without the
relevant I2C controller.

Thanks for pointing this out - I had also a closer look at the codecs and the
other FSI related codec (da7210.c) depends on I2C too.
So maybe even move the dependency up to SND_SOC_SH4_FSI
since both codecs rely on I2C?
So something like this would be more appropriate?
config SND_SOC_SH4_FSI
tristate "SH4 FSI support"
+ depends on CONFIG_I2C_SH_MOBILE
help
This option enables FSI sound support
If you think this patch sounds correct, I can create a new 'official' patch.

No, while the two boards in mainline currently may need I2C obviously
other board designs with other control interfaces are possible so it
should be on the individual boards.

The config option SND_FSI_AK4642 selects SND_SOC_AK4642 which in turn
enables the compilation of ak4642.c - however this codec uses I2C to
communicate with the HW.
Same applies to DA7210.
Consequently when I2C is not set, the compilation fails [1]
This patch fixes this issues, by adding a depencdency on the related HW-
controller.

It uses I2C, but it doesn't matter which I2C master it's interfaced with.
A simple depends on I2C will suffice for this purpose just fine.

Since these are board specific drivers they know which I2C controller they are
hooked up to and so can usefully depend on a specific controller - without the
correct controller driver they will not function.

I don't really mind one way or the other. Having it depend on the
controller is fine, but it's not really much of a stretch to expect it to
show up on other boards with other controllers as well.
Very few SH CPUs use the same controller, so in this case it's really
more the exception than the norm. As soon as another board takes up one
of these blocks then we're forced to either switch to an I2C depends or
start making a dependency list for multiple controllers. It's the desire
to avoid the latter why I generally prefer the former, but again, I'm
fairly impartial regardless.

of these blocks then we're forced to either switch to an I2C depends or
start making a dependency list for multiple controllers. It's the desire
to avoid the latter why I generally prefer the former, but again, I'm
fairly impartial regardless.

This is the driver for the board itself and its wiring - it's not a chip driver, it's
the driver that says how the chips on a given board are connected. For new
boards I'd expect you'd end up with a new driver.
