addresses, so we have a lot of u32 variables around, which are assigned
to pointers and vice versa. This obviously creates issues with 64-bit

To allow compilation for 64-bit boards which use only memory below 4GB
anyway (and to avoid more invasive fixes), adjust some casts and types
and assume that the EDs and TDs are all located in the lower 4GB.

USB ULPI PHY reset signals are typically active low. Consequently, they
should be marked as GPIO_ACTIVE_LOW in device tree, and indeed they are in
the Linux kernel DTs, and in DT properties that U-Boot doesn't yet use.
However, in DT properties that U-Boot does use, the value has been set to
0 (== GPIO_ACTIVE_HIGH) to work around a bug in U-Boot.
This change fixes the DT to correctly represent the HW, and fixes the
Tegra USB driver to cope with the fact that dm_gpio_set_value() internally
handles any inversions implied by the DT value GPIO_ACTIVE_LOW.

The meaning of CONFIG_USB in U-Boot is different from that in Linux.
As you see in drivers/usb/Kconfig of Linux, CONFIG_USB enables the
USB host controller support, while CONFIG_USB_SUPPORT is used to
enable the whole of the USB sub-system.
When I added CONFIG_USB into Kconfig by commit 6e7e9294d3 ("usb:
add basic USB configs in Kconfig"), I planned to follow the Linux's
convention, i.e. CONFIG_USB to enable/disable the USB host support.
Then, commit 68f7c5db2d ("usb: Generic USB Kconfig option, that
fits both host and gadget and comments") changed the logic of the
CONFIG_USB to point to the whole of the USB sub-system. As a result,
currently we do not have an option for USB host.
This commit adds CONFIG_USB_HOST, which will be useful to compile
in the USB host support code.
CONFIG_USB_HOST is not referenced at all, but strangely some boards
define it in board headers. I removed them because USB_HOST will be
selected in Kconfig going forward.

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.

Quite a few places have a bind() method which just calls dm_scan_fdt_dev().
We may as well call dm_scan_fdt_dev() directly. Update the code to do this.

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.

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.

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).

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.

Create an entry for "config USB_XHCI_DWC3" in Kconfig and
switch over to it for all boards.
Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
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.

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).

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.

On the H3 we need to enable the clk and de-assert the reset of the
companion to be able to talk to the actual usb host controller.
Before this commit we were also disabling the companion clk-gate /
asserting its reset on remove, causing the later remove callback of
the companion itself to (sometimes) fail with:
ERROR: USB HC reset timed out!
This commit fixes this by not disabling the companion's clk-gate nor
asserting its reset on remove.
