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, added a: -"depends on !PPC_OF" to Kconfig to avoid a known conflict with PPC-OF platforms -and went with the generic usb-ehci 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-ehci", ie they have: - - compatible = "ti,ehci-omap", "usb-ehci"; - -In theory this should not be a problem since the "ti,ehci-omap" 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 ehci-platform to -"generic-ehci", avoiding the driver registration / module loading ordering -problems, and removes the "depends on !PPC_OF" workaround. - -Signed-off-by: Hans de Goede <hdegoede@redhat.com> ---- - Documentation/devicetree/bindings/usb/usb-ehci.txt | 4 ++-- - drivers/usb/host/Kconfig | 1 - - drivers/usb/host/ehci-platform.c | 2 +- - 3 files changed, 3 insertions(+), 4 deletions(-) - -diff --git a/Documentation/devicetree/bindings/usb/usb-ehci.txt b/Documentation/devicetree/bindings/usb/usb-ehci.txt -index 2c1aeeb..ff151ec 100644 ---- a/Documentation/devicetree/bindings/usb/usb-ehci.txt -+++ b/Documentation/devicetree/bindings/usb/usb-ehci.txt -@@ -1,7 +1,7 @@ - USB EHCI controllers - - Required properties: -- - compatible : should be "usb-ehci". -+ - compatible : should be "generic-ehci". - - reg : should contain at least address and length of the standard EHCI - register set for the device.
