Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.
Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.
[*] Enable foo ---
This is how it would be shown if there were children but they all
happened to be invisible as well.
With a regular 'config', it turns into
[*] Enable foo
Change all pointless 'menuconfig's to 'config's.
See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

Enable LED strip driver for daisy chains of LPD880x
|
|
(LPD8803, LPD8806, or compatible) devices.
|
|
|
|
Each LPD880x LED driver chip has some output channels
|
|
(3 channels for LPD8803, 6 for LPD8806), whose PWM
|
|
duty cycle can be set at 7 bit resolution via a
|
|
reduced SPI interface (MOSI and CLK lines only).
|
|
Each chip also includes data and clock out pins for
|
|
daisy chaining LED strips.
