ARM: Tegra: USB: EHCI: Add support for Tegra30/Tegra114

2013-07-11T21:15:15+00:00

Tegra30 and Tegra114 are compatible except PLL parameters.

Tested on Tegra30 Cardhu, and Tegra114 Dalmore
platforms. All works well.

usb: ehci: add missing cache managment

2013-06-12T20:22:52+00:00

Commit 8f62ca6 "usb: ehci: Support interrupt transfers via periodic list"
didn't include any cache management in the new interrupt transfer path.
It also added an extra write to or_asynclistaddr in usb_lowlevel_init(),
without having flushed out the data there.

Add the missing cache management calls, so that the code works again.

This allows the USB keyboard on Tegra's Seaboard/Springbank boards to
work.

usb: ehci: add Faraday USB 2.0 EHCI support

2013-06-12T20:22:51+00:00

This patch adds support to both Faraday FUSBH200 and FOTG210,
the differences between Faraday EHCI and standard EHCI are
listed bellow:

1. The PORTSC starts at 0x30 instead of 0x44.
2. The CONFIGFLAG(0x40) is not only un-implemented, and
   also has its address space removed.
3. Faraday EHCI is a TDI design, but it doesn't
   compatible with the general TDI implementation
   found at both U-Boot and Linux.
4. The ISOC descriptors differ from standard EHCI in
   several ways. But since U-boot doesn't support ISOC,
   we don't have to worry about that.

usb: ehci: add weak-aliased function for PORTSC

2013-06-12T20:22:51+00:00

There is at least one non-EHCI compliant controller (i.e. Faraday EHCI)
not only leave RESERVED and CONFIGFLAG registers un-implemented
but also has their address spaces removed.

As an result, the PORTSC register of Faraday EHCI always
starts from 0x30 instead of 0x44 in standard EHCI.

So that we'll need a weak-aliased function for abstraction.

usb: ehci: prevent bad PORTSC register access

2013-06-12T20:22:51+00:00

1. The 'index' of ehci_submit_root() is not always > 0.

   e.g.
   While it gets invoked from usb_get_descriptor(),
   the 'index' is always a '0'. (See ch.9 of USB2.0)

2. The PORTSC register is not always required, and thus it
   should only report a port error when necessary.
   It would cause a port scan failure if the ehci_submit_root()
   always gets terminated by a port error.

usb: Correct CLEAR_FEATURE code in ehci-hcd

2013-06-12T20:22:50+00:00

This commit broke USB2 on link (Chromebook Pixel):

  020bbcb usb: hub: Power-cycle on root-hub ports

However the root cause seems to be a missing mask and missing 'break'
in ehci-hcd.c. This patch fixes both.

On link, 'usb start' with a USB keyboard and memory stick inserted now
finds both. The keyboard works as expected. Also ext2ls shows a directory
listing from the memory stick.

usb: common: Use a global definition for 'min3'

2013-05-06T00:16:37+00:00

We can use a common global method for calculating minimum of
3 numbers. Put the same in 'common header' and let 'ehci'
use it.
