41d7a7da80 imx6: clock: improve calculations to get the PLL video rate
During some tests to check the pixel clock rate in the transition from
U-Boot to the Linux kernel, I noticed that with the same configuration
of the registers the debug messages reported different rates.

The same Linux kernel calculations are now used to get the PLL video
rate.

c06597ff11 pci: mpc85xx: Do not access PCI BARs registers of BDF address 00:00.0
At BDF address 00:00.0 is fictional device which PCI configuration header
is for configuring mpc85xx PCI controller itself. PCI config space of this
device has ATMU inbound registers on position of PCI BARs. Trying to do PCI
auto configuration of this device cause rewriting ATMU inbound registers.
To avoid it, do not allow overwriting registers at BARs positions. And
because this device does not have any PCI memory, return zeros when trying
to read PCI BARs config space registers. It signals to auto configuration
tool to not allocate any PCI memory for this device.

This information is taken from MPC8544E Reference Manual, sections
17.3.1.3, 17.3.1.1.1, 17.3.2 and 17.3.2.11. Available at NXP website:

Another bunch of patches that replace old-school U-Boot hacks with
proper DM based code, this time for the raw NAND flash driver, and the
USB PHY VBUS detection code. Plus two smaller patches that were sitting
in my inbox for a while.

Gitlab CI passed. In lack of some supported board with NAND flash I
couldn't really test this part, but apparently this was tested by the
reviewer. I briefly ran the branch on some boards with USB-OTG, and

That CPU board called CMPCPRO has a mpc8321E CPU (Family PQII PRO hence

In order to support that new board, the following changes are included
in this series:
- Make the mpc8xx watchdog driver more generic for reusing it
with mpc83xx
- Fix various small problems on mpc83xx platform
- Add a GPIO Driver for QE GPIOs
- Add support for mpc832x into mpc83xx SPI driver
- Refactor existing board code that will be shared with new board
- Add the new board

ca031c0827 dm: core: introduce uclass_get_device_by_of_path()
There's quite a few instances of board-specific code doing

  off = fdt_path_offset(gd->fdt_blob, ...);
  ...
  ret = uclass_get_device_by_of_offset(..., off, &dev);

looking for an eeprom or a pmic via some alias. Such code can be
simplified a little if we have a helper for directly getting a device
via device tree path (including being given as an alias).

Implement it in terms of ofnode rather than raw offsets so that this
will work whether live tree is enabled or not.

                                 ^~~~~

And a suggestion to just initialize bflow to NULL. This would however
would be ensuring a bad dereference. Instead, looking at the function we
rework things so that when CONFIG_EXPO is not enabled (and so, no UI) we
error early and would never reach this point in the code.  Simplify the
rest slightly as well while at this.

df202d996d phy: sun4i-usb: Do not drive VBUS with external VBUS present
It is possible to use host-side USB with externally-provided VBUS. For
example, some USB OTG cables have an extra power input which powers
both the board and the USB peripheral.

To support this setup, skip enabling the VBUS switch/regulator if VBUS
voltage is already present. This behavior matches the Linux PHY driver.

09cbd3858f gpio: axp/sunxi: Remove virtual VBUS detection GPIO
Now that this functionality is modeled using the device tree and
regulator uclass, the named GPIO is not referenced anywhere. Remove it.

7d5b17cca6 sunxi: Switch to PMIC USB power supply VBUS detection
Update boards to use the USB power supply driver, as referenced in the
device tree, instead of a virtual GPIO. This removes the need for some
DM-incompatible special cases in the GPIO driver.

The following five boards used AXP0-VBUS-DETECT in their config, but are
missing the "usb0_vbus_power-supply" property in their device tree:
 - Ainol_AW1_defconfig / sun7i-a20-ainol-aw1
 - Cubieboard4_defconfig / sun9i-a80-cubieboard4
 - Merrii_A80_Optimus_defconfig / sun9i-a80-optimus
 - Yones_Toptech_BD1078_defconfig / sun7i-a20-yones-toptech-bd1078
 - Yones_Toptech_BS1078_V2_defconfig /
   sun6i-a31s-yones-toptech-bs1078-v2

None of those five boards have the MUSB controller (USB OTG) enabled in
their device trees, so this change should not break anything for them.

Additionally, the following board intentionally omits the property
because VBUS is always enabled:
 - Nintendo_NES_Classic_Edition_defconfig /
   sun8i-r16-nintendo-nes-classic

The PHY driver already assumes VBUS is enabled when no detection method
is available, so again this will not cause any problems.

ee6a678263 power: regulator: Add a driver for the AXP USB power supply
This driver reports the presence/absence of voltage on the PMIC's USB
VBUS pin. This information is used by the USB PHY driver. The
corresponding Linux driver uses the power supply class, which does not
exist in U-Boot. UCLASS_REGULATOR seems to be the closest match.
