This commit does two things: 1. First, it reorganizes the driver Kconfig files so that each is self contained. Before, a part of the driver configuration was in drivers/Kconfig and the rest was in in drivers/xyz/Konfig. Now, all of the driver configuration is consolitated in the latter. 2. Second, this commit correct numerous serious errors introduced in a previous reorganization of the driver Kconfig files. This was first noted by Nicholas Chin in PR270 for the case of the drivers/i2c/Kconfig but some examination indicates that the error was introduced into several other Kconfig files as well. The nature of the introduced error was basically this: - Nothing must intervene between the menuconfig selection and the following conditional configuration otpions. - A previous PR erroneously introduced unconditional options between the menuconfig and the following confditional logic, thus corrupting the driver menus. This error was easy to make because the driver Kconfig files were not well modularized. Making them fully self-contained should eliminate this kind of error in the future.

This selection enables selection of common I2S options. This option

should be enabled by all platforms that support I2S interfaces.

See include/nuttx/audio/i2s.h for further I2S driver information.

|
|
This selection enables a simple character driver that supports I2S
|
|
transfers via a read() and write(). The intent of this driver is to
|
|
support I2S testing. It is not an audio driver but does conform to
|
|
some of the buffer management heuristics of an audio driver. It is
|
|
not suitable for use in any real driver application in its current
|
|
form.

This is a fixed timeout value that will be used for all receiver
