2022-02-17watchdog: armada_37xx: Convert to official DT bindingsPali Rohár
Official DT bindings have only one reg property: watchdog address space. Convert armada-37xx-wdt.c driver to offical DT bindings and access sel_reg register via MVEBU_REGISTER() macro, as its value (required by U-Boot driver) is not in DT yet. In later stage can be driver cleaned to not use it. This change would allow U-Boot to use A3720 watchdog DTS structure from Linux kernel.

2022-02-17arm: a37xx: pci: Ensure that root port is always on root zero busPali Rohár
Writing to the PCI_PRIMARY_BUS register of the root port should not change bus number on which is root port present. This PCI_PRIMARY_BUS register is used only for correct configuration of legacy PCI stuff, like forwarding of PCI special cycles between buses. Aardvark HW does not support PCI special cycles, so it does not have HW register for PCI_PRIMARY_BUS and therefore it does not matter what is stored in this register. So fix this issue and do not use PCI_PRIMARY_BUS register in pci-aardvark.c driver for moving root bus of the root port. After this change there is no reason for storing bus number (zero) into first_busno variable, so remove this variable.

Remove "PCI_" prefix from all macros which are aardvark specific to not conflict with macros defined in global include file pci.h. Instead add "ADVK_" prefix for them so it is visible that they are aardvark specific. After "ADVK_" prefix append keyword which describes register group, so it would be clear to which register each macro value belongs. Rename some macros for consistency with other macros.

And Advanced Error Reporting registers (PCI_ERR_*) start at offset 0x100. Replace custom aardvark register macros by standard PCI macros from include/pci.h file with fixed offset.

2022-02-11DFU: Check the number of arguments and argument string strictlyMasami Hiramatsu
When parsing the dfu_alt_info, check the number of arguments and argument string strictly. If there is any garbage data (which is not able to be parsed correctly) in dfu_alt_info, that means something wrong and user may make a typo or mis- understanding about the syntax. Since the dfu_alt_info is used for updating the firmware, this mistake may lead to brick the hardware. Thus it should be checked strictly for making sure there is no mistake.

2022-02-11DFU: Accept redundant spaces and tabs in dfu_alt_infoMasami Hiramatsu
If dfu_alt_info has repeated spaces or tab (for indentation or readability), the dfu fails to parse it. For example, if dfu_alt_info="mtd nor1=image raw 100000 200000" (double spaces after "raw"), the image entity start address is '0' and the size '0x100000'. This is because the repeated space is not skipped. Use space and tab as a separater and apply skip_spaces() to skip redundant spaces and tabs.

2022-02-11button: adc: set state to pressed when the voltage is closest to nominalPeter Cai
In the Linux implementation of adc-keys (drivers/input/keyboard/adc-keys.c), `press-threshold-microvolt` is not really interpreted as a threshold, but rather as the "nominal voltage" of the button. When the voltage read from the ADC is closest to a button's `press-threshold-microvolt`, the button is considered pressed. This patch reconciles the behavior of button-adc with Linux's adc-keys such that device trees can be synchronized with minimal modifications. Signed-off-by: Peter Cai <peter@typeblog.net>

2022-02-11usb: ehci-mx6: Enable OTG detection on imx8mm and imx8mnAdam Ford
The imx8mm and imx8mn appear compatible with imx7d-usb flags in the OTG driver. If the dr_mode is defined as host or peripheral, the device appears to operate correctly, however the auto host/peripheral detection results in an error. The solution isn't just adding checks for imx8mm and imx8mn to the check for imx7, because the USB clock needs to be running to read from the USBNC_PHY_STATUS_OFFSET register or it will hang. Marek requested that I not enable the clocks in ehci_usb_of_to_plat, so I modified that function to return an unknown state if the device tree does not explicitly state whether it is a host or a peripheral. When the driver probes, it looks to see if it's in the unknown state, and only then will it read the register to auto-detect.
