usb: exynos5: arndale: Add network support

2014-01-13T11:23:28+00:00

Arndale board has AX88760, which is USB 2.0 Hub & USB 2.0 Ethernet Combo
controller, connected to HSIC Phy of USB host controller via USB3503 hub.

This patch uses board specific board_usb_init function to perform reset
sequence for USB3503 hub and enables the relevant config options for
network to work.

usb: ehci: exynos: set/reset hsic phys

2014-01-13T11:23:28+00:00

The controller has 3 ports. The port0 is for USB 2.0 Phy, port1 and port2
are for HSIC phys. The usb 2.0 phy is already being setup. This patch
sets up the hsic phys.

usb: gadget: fotg210: EP0 fifo empty indication is non-reliable

2014-01-13T11:15:13+00:00

The fifo size of ep0 is 64 bytes, and if the packet size grater than
64 bytes, the driver would have to fill up the fifo multiple times,
and before filling up the fifo, the driver should make sure the fifo
is empty by checking fifo empty indication.

However there is a hardware bug that the fifo empty indication is
somehow a bit earlier than fifo reset. So if I don't add an extra
delay here, the data might be corrupted. (i.e., 1 byte missing)

After a couple of tests, it truns out that 1 usec is good enough.

This workaround should be applied to all hardware revisions.

usb: gadget: fotg210: add w1c interrupt status support

2014-01-13T11:15:12+00:00

Since hardware revision 1.11.0, the following interrupt status
registers are now W1C (i.e., write 1 clear):

1. Interrupt Source Group 0 Register (0x144) (EP0 Abort: BIT5)
2. Interrupt Source Group 2 Register (0x14C) (All bits)

And before revision 1.11.0, these registers are all R/W.
Which means software must write a 0 to clear the status.

usb: ehci: Fix register access

2013-12-18T18:53:19+00:00

Fix the register access in EHCI HCD. We need to use address of the register
as an ehci_writel() argument.

usb: ehci: Do not de-init uninited controllers

2013-12-18T18:53:19+00:00

In case the controller is not initialized, we shall not de-initialize it.
As the control structure will not be filled, we will produce a null ptr
dereference if the controller is not inited.

usb: ehci-pci: Clarify and cleanup the EHCI controller detection

2013-12-18T18:53:19+00:00

The detection function of the EHCI PCI controller was really cryptic,
add a beefy comment and clean the portion of the code up a bit. No
change in the logic of the code.

usb: dfu: f_dfu: Provide infrastructure to adjust DFU's Poll Timeout value

2013-12-18T18:53:19+00:00

It is necessary to deter the host from sending subsequent DFU_GETSTATUS
request in the case of e.g. writing the buffer to medium.

Here the timeout is increased when we fill up the whole buffer. This delay
allows eMMC memory to perform its internal operations.
Otherwise we end up with HOST's error regarding GET_STATUS receive timeout.

drivers/usb/gadget: select objects by obj-$(CONFIG-...)

2013-12-13T14:18:44+00:00

Before switching to the real Kbuild, drivers/usb/gadget/Makefile
must be fixed.
If none of CONFIG_USB_GADGET, CONFIG_USB_ETHER, CONFIG_USB_DEVICE
is defined, both obj- and obj-y get empty.

We need non-empty obj- or obj-y on each Makefile
to generate built-in.o on the real Kbuild.
