There are multiple places in usb core or controller driver which returns
-EMSGSIZE when a class driver queueing urb failed, so the "Message too

Let the musb driver to specifically print a error message when
musb_urb_enqueue() returns -EMSGSIZE.

commit 68fe05e2a4 ("usb: musb: fix tx fifo flush handling") drops the
1ms delay trying to solve the long disconnect time issue when
application queued many tx urbs. However, the 1ms delay is needed for
some use cases, for example, without the delay, reconnecting AR9271 WIFI
dongle no longer works if the connection is dropped from the AP.
So let's add back the 1ms delay in musb_h_tx_flush_fifo(), and solve the
long disconnect time problem with a separate patch for
usb_hcd_flush_endpoint().

Commit d8e5f0eca1 ("usb: musb: Fix hardirq-safe hardirq-unsafe
lock order error") caused a regression where musb keeps trying to
enable host mode with no cable connected. This seems to be caused
by the fact that now phy is enabled earlier, and we are wrongly
trying to force USB host mode on an OTG port. The errors we are
getting are "trying to suspend as a_idle while active".
For ports configured as OTG, we should not need to do anything
to try to force USB host mode on it's OTG port. Trying to force host
mode in this case just seems to completely confuse the musb state
machine.
Let's fix the issue by making musb_host_setup() attempt to force the
mode only if port_mode is configured for host mode.

During dma teardown for dequque urb, if musb load is high, musb might
generate bogus rx ep interrupt even when the rx fifo is flushed. In such
case any of the follow log messages could happen.
musb_host_rx 1853: BOGUS RX2 ready, csr 0000, count 0
musb_host_rx 1936: RX3 dma busy, csr 2020
As mentioned in the current inline comment, clearing ep interrupt in the
teardown path avoids the bogus interrupt.
Clearing ep interrupt is platform dependent, so this patch adds a
platform callback to allow glue driver to clear the ep interrupt.
This bug seems to be existing since the initial driver for musb support,
but I only validated the fix back to v4.1, so only cc stable for v4.1+.

The data thrown away was a valid packet that had been correctly

Here are a few changes in musb_h_tx_flush_fifo().
- It has been observed that sometimes (if not always) musb is unable
to flush tx fifo during urb dequeue when disconnect a device. But
it seems to be harmless, since the tx fifo flush is done again in
musb_ep_program() when re-use the hw_ep.
But the WARN() floods the console in the case when multiple tx urbs
are queued, so change it to dev_WARN_ONCE().
- applications could queue up many tx urbs, then the 1ms delay could
causes minutes of delay in device disconnect. So remove it to get
better user experience. The 1ms delay does not help the flushing
anyway.
- cleanup the debug code - related to lastcsr.
----
Note: The tx fifo flush issue has been observed during device disconnect
on AM335x.
To reproduce the issue, ensure tx urb(s) are queued when unplug the usb
device which is connected to AM335x usb host port.
I found using a usb-ethernet device and running iperf (client on AM335x)
has very high chance to trigger the problem.
Better to turn on dev_dbg() in musb_cleanup_urb() with CPPI enabled to
see the issue when aborting the tx channel.

musb_host_cleanup() which does basically usb_remove_hcd() and also sets

musb_host_free() basically a nop and the usb_hcd remains around for ever
without anowner.
This patch drops that NULL assignment for that reason.

The musb/cppi41 glue layer is capable of handling transactions that span
over more than one USB packet by reloading the DMA descriptors
partially. An urb is considered completed when either its transfer
buffer has been filled entirely (actual_length ==
transfer_buffer_length) or if a packet in the stream has less bytes than
the endpoint's wMaxPacketSize.
Once one of the above conditions is met, musb_dma_completion() is called
from cppi41_trans_done(). However, the final decision whether or not to
return the urb to its owner is made by the core and its determination of
the variable 'done' in musb_host_rx(). This code has currently no way of
knowing what the size of the last packet was, and whether or not to
give back the urb due to a short read.
Fix this by introducing a new boolean flag in 'struct dma_channel', and
set it from musb_cppi41.c. If set, it will make the core do what the
DMA layer decided and complete the urb.

- removal of unnecessary lock on dwc3-omap.c
Signed-of-by: Felipe Balbi <balbi@ti.com>
Individual controller driver has different requirement for wakeup
setting, so move it from core to itself. In order to align with
current etting the default wakeup setting is enabled (except for
chipidea host).
Pass compile test with below commands:
make O=outout/all allmodconfig
make -j$CPU_NUM O=outout/all drivers/usb

The dsps platform needs to save save some registers at suspend time and
restore them after resume. This patch adds a struct for these registers,
and also lets the musb core know that the core registers need to be
saved as well.
We also have to explicitly de-assert the port reset upon resume on this
platform, but musb_port_reset() should not be called from glue layers.
Hence, introduce a flag in struct musb_hdrc_config for this.

Make musb_port_suspend() externally available, and call it when to host
goes into suspend. This allows the core to go into suspend while a
device is connected.

These aren't necessary after switch and if blocks.

musb_shutdown() removes always USB host and device.
musb_init_controller() adds host and device depending on port_mode. If
port mode is set to HOST then the removal of UDC leads only to:
|(NULL device *): gadget not registered.
and nothing else happens. If port mode is set to DEVICE and we remove
the host then we oops in usb_remove_hcd().
This patch ensures that we only remove host in OTG/host mode and device
only in OTG/device mode to avoid any trouble.

All function drivers are now converted to our new configfs-based
binding. Eventually this will help us getting rid of in-kernel
gadget drivers and only keep function drivers in the kernel.
MUSB was taught that it needs to be built for host-only and
device-only modes too. We had this support long ago but it
involved a ridiculous amount of ifdefs. Now we have a much
cleaner approach.
Samsung Exynos4 platform now implements HSIC support.
We're introducing support for AB8540 and AB9540 PHYs.
MUSB module reinsertion now works as expected, before we were
getting -EBUSY being returned by the resource checks done on
driver core.
DWC3 now has minimum support for TI's AM437x series of SoCs.
OMAP5 USB3 PHY learned one extra DPLL configuration values because
that PHY is reused in TI's DRA7xx devices.
We're introducing support for Faraday fotg210 UDCs.
Last, but not least, the usual set of non-critical fixes and cleanups
ranging from usage of platform_{get,set}_drvdata to lock improvements.
