usb: musb: host: rely on port_mode to call musb_start()

2015-07-06T17:34:07+00:00

Currently, we're calling musb_start() twice for DRD ports in some situations. This has been observed to cause enumeration issues after suspend/resume cycles with AM335x. In order to fix the problem, we just have to fix the check on musb_has_gadget() so that it only returns true if current mode is Host and ignore the fact that we have or not a gadget driver loaded. Fixes: ae44df2e21b5 (usb: musb: call musb_start() only once in OTG mode) Cc: Sebastian Andrzej Siewior Cc: # v3.11+ Tested-by: Sekhar Nori Signed-off-by: Felipe Balbi

Merge 4.1-rc7 into usb-next

2015-06-08T17:57:51+00:00

This resolves a merge issue in musb_core.c and we want the fixes that were in Linus's tree in this branch as well for testing. Signed-off-by: Greg Kroah-Hartman

usb: musb: Fix platform code being unable to override ep access ops

2015-05-26T15:47:13+00:00

musb-core was setting the ops to the default indexed or flat handlers after checking for platform overrides. Reverse the order of this so that platform overrides actually work. Signed-off-by: Hans de Goede Signed-off-by: Felipe Balbi

usb: musb: Do not use musb_read[b|w] / _write[b|w] wrappers in generic fifo functions

2015-05-26T15:46:59+00:00

The generic fifo functions already use non wrapped accesses in various cases through the iowrite#_rep functions, and all platforms which override the default musb_read[b|w] / _write[b|w] functions also provide their own fifo access functions, so we can safely drop the unnecessary indirection from the fifo access functions.

usb: musb: Make busctl_offset an io-op rather then a define

2015-05-26T15:46:54+00:00

The Allwinner (sunxi) implementation of the musb has its busctl registers indexed by the MUSB_INDEX register rather then in a flat address space. This commit turns MUSB_BUSCTL_OFFSET from a macro into an io-op which can be overridden from the platform ops. Signed-off-by: Hans de Goede Signed-off-by: Felipe Balbi

usb: musb: Make musb_write_rxfun* and musb_write_rxhub* work like their tx versions

2015-05-26T15:46:45+00:00

For some reason the musb_write_rxfun* and musb_write_rxhub* functions had a different function prototype and some extra magic needed on the caller side compared to their tx counterparts, this commit makes them work the same as their tx counterparts.

usb: musb: Add pre and post root port reset end callbacks

2015-05-26T15:38:24+00:00

The sunxi otg phy has a bug where it wrongly detects a high speed squelch when reset on the root port gets de-asserted with a lo-speed device. The workaround for this is to disable squelch detect before de-asserting reset, and re-enabling it after the reset de-assert is done. Signed-off-by: Hans de Goede Signed-off-by: Felipe Balbi

usb: musb: fix order of conditions for assigning end point operations

2015-05-26T15:15:10+00:00

Currently we always assign one of the two common implementations of ep_offset and ep_select operations, overwriting any platform-specific implementations. Fixes: d026e9c76aac ("usb: musb: Change end point selection to use ...") Signed-off-by: Ben Hutchings Signed-off-by: Felipe Balbi
