From 7675d6ba436f8439fc524ee0b42dc562cb1bc74e Mon Sep 17 00:00:00 2001 From: Manjunath Goudar Date: Tue, 2 Apr 2013 18:24:00 +0200 Subject: USB: EHCI: make ehci-spear a separate driver Separate the SPEAr host controller driver from ehci-hcd host code so that it can be built as a separate driver module. This work is part of enabling multi-platform kernels on ARM; however, note that other changes are still needed before SPEAr can be booted with a multi-platform kernel, but they are queued in the arm-soc tree for 3.10. With the infrastructure added by Alan Stern in patch 3e0232039 "USB: EHCI: prepare to make ehci-hcd a library module", we can avoid this problem by turning a bus glue into a separate module, as we do here for the SPEAr bus glue. In V4 (arnd): - renamed all 'struct spear_ehci' pointers from 'ehci' to the less ambiguous 'sehci'. - folded trivial spear_start_ehci/spear_stop_ehci functions into callers. - brought back initialization of ehci->caps. In V3: - Detailed commit message added here about why this patch is required. - Eliminated ehci_spear_setup routine because hcd registers can be directly set in the spear_ehci_hcd_drv_probe function. - spear_overrides struct initialized. - Converted to using .extra_priv_size for allocating spear_ehci, and updated all users of that structure. - to_spear_ehci() macro modified for spear_ehci. In V2: - Replaced spear as SPEAr everywhere, leaving functions/variables/config options.
