Hello I have been trying to get the WL1273 FM radio driver into the kernel for some time. It has been kind of difficult, one of the reasons is that I didn't realize I should have tried to involve all relevant maintainers to the discussion form the beginning (AsoC, Media and MFD). At Mark's suggestion I'm trying to reopen the discussion now. The driver consists of an MFD core and two child drivers (the audio codec and the V4L2 driver). And the question is mainly about the role of the MFD driver: the original design had the IO functions in the core. Currently the core is practically empty mainly because Mauro very strongly wanted to have âeverythingâ in the V4L2 driver. I liked the original design because it didn't have the bug that the current MFD has: the codec can be initialized before the V4L2 part sets the IO function pointers. Having in principle equally capable interface drivers is symmetrical and esthetically pleasing:-) Also somebody could easily leave out the existing interfaces and create a completely new one based for example to sysfs or something... Having the IO in the core would also conveniently hide the physical communication layer and make it easy to change I2C to UART, which is also supported by the chip.
