2021-06-05of: addr: Translate 'dma-ranges' for parent nodes missing 'dma-ranges'Bin Meng
'dma-ranges' frequently exists without parent nodes having 'dma-ranges'. While this is an error for 'ranges', this is fine because DMA capable devices always have a translatable DMA address. Also, with no 'dma-ranges' at all, the assumption is that DMA addresses are 1:1 with no restrictions unless perhaps the device itself has implicit restrictions.

2021-06-04arm: a37xx: pci: Fix configuring PCIe resourcesPali Rohár
The `ranges` DT property of the PCIe node is currently ignored by Aardvark driver - all entries are used as transparent PCIe MEM, despite some of them being defined for IO in DT. This is because the driver does not setup PCIe outbound windows and thus a default configuration is used. This can cause an external abort on CPU when a device driver tries to access non-MEM space. Setup the PCIe windows according to the `ranges` property for all non-MEM resources (currently only IO) and also non-transparent MEM resources. Because Linux expects that bootloader does not setup Aardvark PCIe windows, disable them before booting Linux.

Disable Root Bridge I/O space, memory space and bus mastering in Aardvark's remove method, which is called before booting Linux kernel. This ensures that PCIe device which was initialized and used by U-Boot cannot do new DMA transfers until Linux initializes PCI subsystem and loads appropriate drivers for the device. During initialization of PCI subsystem Linux in fact disables this bus mastering on Root Bridge (and later enables it when driver is loaded and configured), but there is a possibility of a small window after U-Boot boots Linux when bus mastering is enabled, which is not correct.

2021-06-04arm: a37xx: pci: Don't put link into LTSSM Recovery state during probePali Rohár
During our debugging of the Aardvark driver in Linux we have discovered that the PCIE_CORE_LINK_CTRL_STAT_REG register in fact controls standard PCIe Link Control Register for PCIe Root Bridge. This led us to discover that the name of the PCIE_CORE_LINK_TRAINING macro and the corresponding comment by this macro's usage is misleading; this bit in fact controls Retrain Link, which, according to PCIe base spec is defined as: A write of 1b to this bit initiates Link retraining by directing the Physical Layer LTSSM to the Recovery state. If the LTSSM is already in Recovery or Configuration, re-entering Recovery is permitted but not required. Entering Recovery state is normally done from LTSSM L0, L0s and L1 states. But since the pci-aardvark.c driver enables Link Training just a few lines above, the controller is not in L0 ready state yet. So setting aardvark bit PCIE_CORE_LINK_TRAINING does not actually enter Recovery state at this place. Moreover, trying to enter LTSSM Recovery state without other configuration is causing issues for some cards (e.g. Atheros AR9xxx and QCA9xxx). Since Recovery state is not entered, these issues are not triggered. Remove code which tries to enter LTSSM Recovery state completely.

2021-05-24regmap: fix a serious pointer casting bugMarek Behún
There is a serious bug in regmap_read() and regmap_write() functions where an uint pointer is cast to (void *) which is then cast to (u8 *), (u16 *), (u32 *) or (u64 *), depending on register width of the map. For example given a regmap with 16-bit register width the code int val = 0x12340000; regmap_read(map, 0, &val); only changes the lower 16 bits of val on little-endian machines. The upper 16 bits will remain 0x1234. Nobody noticed this probably because this bug can be triggered with regmap_write() only on big-endian architectures (which are not used by many people anymore), and on little endian this bug has consequences only if register width is 8 or 16 bits and also the memory place to which regmap_read() should store it's result has non-zero upper bits, which it seems doesn't happen anywhere in U-Boot normally. CI managed to trigger this bug in unit test of dm_test_devm_regmap_field when compiled for sandbox_defconfig using LTO. Fix this by utilizing an union { u8; u16; u32; u64; } and reading data into this union / writing data from this union.

There is a third case, for some boards (with switch), the MDIO is used for switch configuration, but the interface itself uses fixed link. This patch allows this option by checking if fixed-link subnode is defined, in this case, MDIO bus is registers, but the PHY address is set to PHY_MAX_ADDR for this interface, so this interface will not try to access the PHY later on.
