Hi Mark
+config SND_FSI_WM8978
- tristate "FSI-WM8978 sound support"
- depends on SND_SOC_SH4_FSI
- select SND_SOC_WM8978
select SND_FSI_CODEC- help
This option enables generic sound support for theFSI - WM8978 unitRather than having an explicit Kconfig option like this it might be more sensible to have the boards select their CODEC driver. We should only build the CODEC driver if the user enables the subsystem IIRC so this shouldn't be a big cost. You could then just have a single Kconfig for the simple driver.
OK. I understand. I guess this opinion is not only for this "FSI-WM8978" but also for existing cards.
Hmm... If board selects their CODEC driver, the driver will be forcefully included to kernel. And some of these are depend on extra config like I2C. I'm afraid about this kind of "forcefully select".
Of course we can create selectable Kconfig for each boards. but it is just complex..
