-Having "bool ohci" argument bounded us to two cases only and didn't
-allow re-using this code for XHCI.
+Having "bool ohci" argument in bcma_hcd_create_pdev function limited it
+to support two cases only (OHCI and EHCI) and put too much logic in it.
+Lets make caller pass all required data. This adds few extra arguments
+to the function call but will allow us to reuse this code and handle
+more cases in the future (e.g. add XHCI support).

+Subject: [PATCH] USB: bcma: separate code initializing USB 2.0 core
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
-This will allow adding USB 3.0 (XHCI) support cleanly.
+This splits one big probing function into two smaller ones. The main one
+is now responsible for the generic stuff: allocating memory & enabling
+power using GPIO. The new one contains code that is specific to the USB
+2.0 bcma core.
+This will allow adding support for the USB 3.0 bcma core (handling XHCI)
+in the future.
