ehci: mx7: fix otg id detection

2016-06-24T22:57:10+00:00

The USBNC_PHYCFG2_ACAENB bit should be cleared to enable the
OTG ID detection, not set it. When the bit is set, the ACA
Resistance Detection is enabled, which disables the OTG ID
detection, because the internal pull up is off.

clk: convert API to match reset/mailbox style

2016-06-19T23:05:55+00:00

The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
  provider now implements a single set of clocks. This provides a simpler
  conceptual interface to clients, and better aligns with device tree
  clock bindings.
* Clocks are now identified with a single "struct clk", rather than
  requiring clients to store the clock provider device and clock identity
  values separately. For simple clock consumers, this isolates clients
  from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
  clk-uclass.h contains the provider API. This aligns with the recently
  added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
  can customize these operations if needed. This also aligns with the
  recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
  clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.

Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

test/py passes for sandbox (which invokes the dm clk test amongst
others).

usb: ehci: only shutdown opened controller

2016-06-17T22:49:00+00:00

If the usb controller is not running, no need to shutdown it,
otherwise `usb stop` complains about:
"EHCI failed to shut down host controller".

To i.MX7D SDB, there are two usb ports, one Host, one OTG.
If we only plug one udisk to the Host port and then `usb start`,
the OTG controller for OTG port does not run actually. Then,
if `usb stop`, the OTG controller for OTG port will also be
shutdown, but it is not running.

This patch adds a check to only shutdown the running controller.

usb: move CONFIG_USB_XHCI_DWC3 to Kconfig

Create an entry for "config USB_XHCI_DWC3" in Kconfig and
switch over to it for all boards.

usb: move CONFIG_USB_XHCI to Kconfig with renaming

2016-06-03T22:43:53+00:00

Move CONFIG_USB_XHCI to defconfig files for all boards, renaming it
into CONFIG_USB_XHCI_HCD.

As commented in the help of "config USB_XHCI" entry, this has been
a TODO for a long time; now CONFIG_USB_XHCI_HCD and CONFIG_USB_XHCI
have been unified in favor of the former.

Note:
Some boards define CONFIG_USB_XHCI in their headers without
CONFIG_USB, which does not meet the "depends on" in Kconfig.
I added CONFIG_USB=y for those boards when converting.
Otherwise, they would fail to build.

usb: dwc2: Add delay to fix the USB detection problem on SoCFPGA

2016-05-06T18:06:56+00:00

With patch c998da0d (usb: Change power-on / scanning timeout handling),
the USB scanning is started earlier and with a smaller timeout. This
resulted on SoCFPGA (using the DWC2 driver) in some USB sticks not
getting detected any more. This patch now adds a 1 second delay (in
the host mode only) to the DWC2 driver before the scanning is started.
With this delay, now all problematic USB keys are detected successfully
again. And there is no need any more to change the delay / timeout
in the common USB code (usb_hub.c).

usb: ehci-mx6: allow board_ehci_hcd_init to fail

2016-05-06T16:33:26+00:00

There could be runtime determined board specific reason why a EHCI
initialization fails (e.g. ENODEV if a Port is not available). In
this case, properly return the error code.
While at it, that function (board_ehci_hcd_init) has actually two
documentation blocks... Use the correct function name for the
documentation block of board_usb_phy_mode.
