According to AM572x DM SPRS953A, QSPI bus speed can be 76.8MHz, hence
update QSPI input clock divider value (DPLL_PER_HS13) to provide 76.8MHz
clock, so that driver can use the same.

As per commit b545a98f ("spi: ti_qspi: Add delay
for successful bulk erase) says its added to meet bulk erase timing
constraints. But bulk erase is a cmd to flash and delay in read path
does not make sense. Morever, testing on DRA74/DRA72 evm has shown that
this delay is no longer required.

Populating QSPI_RD_SNGL bit(0x1) in priv->cmd means that value
QSPI_INVAL (0x4) is not written to CMD field of QSPI_SPI_CMD_REG in
ti_qspi_cs_deactivate(). Therefore CS is never deactivated between
successive READ ID which results in sf probe to fail.
Fix this by not populating priv->cmd with QSPI_RD_SNGL and OR it wih
priv->cmd as required (similar to the convention followed in the
driver).

boards. The board also uses the UART's in DTE mode, hence making

The IMX6 PCIe host controller does not have a proper reset and as such there
are several issues that can arise if PCI is enabled in the bootloader follwed
by Linux trying to re-configure LTSSM and/or toggling PERST# to the devices.

For now, the best approach seems to default to disabling PCI by defaulting
pciedisable=1. This can be overridden by the user if they need PCI in the
bootloader, for example:
 - GW552x needing ethernet access in bootloader
 - GW16082 expansion board needing a device-tree fixup for irq mapping

The GW16082 mini-PCI expansion mezzanine uses a TI XIO2001 PCIe-to-PCI
bridge with legacy INTA/B/C/D interrupts. These interrupts are assigned
in the reverse order according to the PCI spec.

If the TI bridge is found on the Ventana PCI bus, add device-tree nodes
according to bus enumeration explicitly defining the interrupt mapping
to override the default PCI mapping in the Linux kernel. This allows
the GW16082 to work with upstream kernels that support device-tree
irq parsing.
