Subject: [PATCH] ohci-platform: Change compatible string from usb-ohci to
|
||
|
|
generic-ohci
|
||
|
|
|
||
|
|
The initial versions of the devicetree enablement patches for ohci-platform
|
||
|
|
used "ohci-platform" as compatible string. However this was disliked by various
|
||
|
|
reviewers because the platform bus is a Linux invention and devicetree is
|
||
|
|
supposed to be OS agnostic. After much discussion I gave up and went with
|
||
|
|
the generic usb-ohci as requested.
|
||
|
|
|
||
|
|
In retro-spect I should have chosen something different, the dts files for many
|
||
|
|
existing boards already claim to be compatible with "usb-ohci", ie they have:
|
||
|
|
|
||
|
|
compatible = "ti,ohci-omap3", "usb-ohci";
|
||
|
|
|
||
|
|
In theory this should not be a problem since the "ti,ohci-omap3" entry takes
|
||
|
|
presedence, but in practice using a conflicting compatible string is an issue,
|
||
|
|
because it makes which driver gets used depend on driver registration order.
|
||
|
|
|
||
|
|
This patch changes the compatible string claimed by ohci-platform to
|
||
|
|
"generic-ohci", avoiding the driver registration / module loading ordering
|
||
|
|
problems.
