-SD card was working in 1-bit mode.This patch will configure SD card in
-4-bit mode and hence performance will increase.

-X-Git-Url: http://git.mansr.com/?p=linux-omap;a=commitdiff_plain;h=2e6aa4efb0e14c51ff0427927b1b38136911fa93

-
-MUSB: Workaround for simultaneous TX and RX usage
-
-MUSB RTL V1.4 has a hardware issue which results in a DMA controller
-hang when TX and RX DMA channels are simultaneously enabled. This
-affects at least OMAP2430 and OMAP34XX.
-
-Since RX transfers are in Mode 0 and anyway result in one DMA interrupt
-per packet, we can use System DMA to unload the RX fifos. MUSB DMA can
-be used for all TX channels as before.
-
-Tested with full-duplex TX and RX transfers using g_ether. Runs for 24
-hours without a hang. Without this patch, the hang occurs within minutes.
-
-This issue was first reported by Jon Hunter on [1]

+Subject: [PATCH] MUSB: Fix for kernel panic with multiple bulk transfer
+Date: Wed, 1 Oct 2008 13:08:56 +0530
+
+Fixes kernel panic when multiple copy is performed among more than two mass
+storage media and transfer is aborted.musb_advance_schedule(),
+musb_urb_dequeue(),musb_cleanup_urb() and musb_h_disable() functions have
+been modified to correct urb handling associated with bulk and control
+endpoints which are multiplexed on one hardware endpoint.
+
+musb_advance_schedule() has been removed from musb_cleanup_urb() and added
+to musb_urb_dequeue(). musb_h_disable() has been modified to take care of
+multiple qh on same hw_ep scenario.

+Suggestions welcome to move while loop doing kfree(qh) from
+musb_advance_schedule() and musb_h_disable() to musb_giveback().
