bb42fb4f10 dm: ehci-mx6: support driver model
Support driver model for ehci mx6 driver.
Consolidate code to be shared between DM and non-DM, such as
introducing ehci_mx6_common_init.
For simplicity, some old fasion code are keeped for DM usage,
such as board_ehci_power and board_usb_phy_mode. And 'dr-mode',
usbphy and vbus handling code for DM is not added now.
These will be added in future patches.

c4483093f3 usb: ehci-mx6: introduce config for high active power pin
Add a new config CONFIG_MXC_USB_OTG_HACTIVE which configures the
OTG Power Pin to be high active. Low active is the reset value
of the affected configuration register, hence the config option
is named by the non-reset configuration.

57de41e9c9 ehci: mx7: fix otg id detection
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.

79d867c2e6 usb: ehci-mx6: allow board_ehci_hcd_init to fail
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.

e162c6b1a7 usb: Rename ehci-fsl.h to ehci-ci.h
Most of ehci-fsl header describe USB controller
designed by Chipidea and used by various SoC vendors.

This patch renames it to a generic header: ehci-ci.h
Contents of file are not changed (so it contains several
references to freescale SoCs).

229dbba9b1 usb:ehci-mx6 add phy mode query function
usb_phy_enable should return status bit, but not phy mode bit, thus
add a new function usb_phy_mode to query the PHY for it's mode and
make usb_phy_enable just return 0 but not 'phy_ctrl & USBPHY_CTRL_OTG_ID'.

Include a new board weak function board_usb_phy_mode. If board code
does not reimplement this function, it just call usb_phy_mode and return
usb_phy_mode's return value. The reason to include such a weak function
is: " SOC OTG core <--connect--> board HOST port, but no pin id for
the board host port, so board can not use usb_phy_mode to return the
phy mode, but define it's own rule."

5546ad0734 usb: ehci-mx6: Rename the USB register base address
The mx6sl/mx6sx has 2 OTG and 1 host. So they have name
"USBO2H_USB_BASE_ADDR" in imx-regs.h. The driver hard codes
the USB base address name to "USBOH3", which causes the driver
failed to build for mx6sl/mx6sx.

This patch uniform the address name to "USB_BASE_ADDR" for all
mx6 series.

d1a5286099 usb: ehci-mx6: add support for otg port
Previously, only host1 was supported using an index of 0.
Now, otg has index 0, host1 is 1, host2 is 2, host3 is 3.
Since OTG requires usbmode to be set after reset, I added
CONFIG_EHCI_HCD_INIT_AFTER_RESET to nitrogen6x.h and
mx6qsabreauto.h.

I also added a weak function board_ehci_power to handle
turning power on/off for otg.

Type is type of device connected (USB stick vs Host.)
Init is type of device desired.
Only power up port if type == init == USB_INIT_HOST.
Only return error if type != init.

f22e4fae19 ehci-mx5/6: Make board_ehci_hcd_init() optional
A custom board_ehci_hcd_init() may be unneeded, so add a weak default
implementation doing nothing.

By the way, use simple __weak from linux/compiler.h for
board_ehci_hcd_postinit() instead of weak alias with full attribute.

676ae068d9 usb: ehci: rework to take advantage of new lowlevel interface
Kill off ehci-core.h
It was used to specify some static controller data. To support more than
one controller being active at any time we have to carry the controller
data ourselfes. Change the ehci interface accordingly.

NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed
to do the same thing as other platforms. But the change for now is at least
compile clean.
