Add upstream send AR724x PCIe patches to get the PCIe controller out of reset during driver init. The AVM Fritz 300E bootloader doesn't take care of releasing the different PCIe controller related resets which causes an endless hang as soon as either the PCIE Reset register (0x180f0018) or the PCI Application Control register (0x180f0000) is read from.

Subject: [PATCH] MIPS: ath79: fix AR724X_PLL_REG_PCIE_CONFIG offset
|
|
|
|
According to the QCA u-boot source the "PCIE Phase Lock Loop
|
|
Configuration (PCIE_PLL_CONFIG)" register is for all SoCs except the
|
|
QCA955X and QCA956X at offset 0x10.
|
|
|
|
Since the PCIE PLL config register is only defined for the AR724x fix
|
|
only this value. The value is wrong since the day it was added and isn't
|
|
yet used by any driver.
