Subject: [PATCH] usb: chipidea: improve kconfig 2.0
|
|
|
|
This patch provides a cleaner solution to the problem described in
|
|
commit 20a677fd ("usb: chipidea: improve kconfig").
|
|
|
|
The goal to be achieved is to force USB_CHIPIDEA=m if either
|
|
USB_EHCI_HCD=m or USB_GADGET=m.
|
|
If both are 'y' USB_CHIPIDEA may be selected to be 'm' or 'y'.
|
|
|
|
The old patch had the drawback, that USB_CHIPIDEA could be chosen as
|
|
'y' though USB_EHCI_HCD or USB_GADGET (or both) were 'm' leading to a
|
|
situation where USB_CHIPIDEA_HOST or USB_CHIPIDEA_UDC vanished from
|
|
the config options producing a compilable but dysfunctional driver.
