2cb7b900f4 ehci-pci: Prepare for usage of readl()/writel() accessors
We used to have opencoded ehci_readl()/writel() which required no

Now with attempt to switch to generic readl()/writel() accessors
we see a missing declaration of those accessors in ehci-ppc4xx.
Something like that happens if applied

a821c4af79 dm: Rename dev_addr..() functions
These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

A weak version of the function board_usb_init is implemented in:
common/usb.c
drivers/usb/host/xhci-omap.c

To fix the double implementations:
* Convert the board_usb_init function in drivers/usb/host/xhci-omap.c
  normal (not weak).
* The function board_usb_init in drivers/usb/host/xhci-omap.c calls to
  the weak function omap_xhci_board_usb_init.
* Rename board version of the function board_usb_init to
  omap_xhci_board_usb_init.
  Done only for boards that defines CONFIG_USB_XHCI_OMAP.

To achieve the same flexibility with the function board_usb_cleanup:
* Add a normal (not weak) implementation of the function
  board_usb_cleanup in drivers/usb/host/xhci-omap.c
* The function board_usb_cleanup in drivers/usb/host/xhci-omap.c calls
  to the weak function omap_xhci_board_usb_cleanup.
* Rename board version of the function board_usb_cleanup to
  omap_xhci_board_usb_cleanup.
  Done only for boards that defines CONFIG_USB_XHCI_OMAP.

57faca19a8 drivers: USB: OHCI: allow compilation for 64-bit targets
OHCI has a known limitation of allowing only 32-bit DMA buffer
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
systems, so the compiler complains here and there.
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.
This fixes compilation of the OHCI driver for the Pine64.

e915716a5c drivers: usb: xhci-fsl: Change burst beat and outstanding pipelined transfers requests
This is required for better performance, and performs below tuning:
1. Enable burst length set, and define it as 4/8/16.
2. Set burst request limit to 16 requests.

2f6a7e8ce5 ARM: tegra: fix USB ULPI PHY reset signal inversion confusion
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.
