PCI: qcom: Make sure PCIe is reset before init for rev 2.1.0

2020-11-05T10:51:50+00:00

commit d3d4d028afb785e52c55024d779089654f8302e7 upstream. Qsdk U-Boot can incorrectly leave the PCIe interface in an undefined state if bootm command is used instead of bootipq. This is caused by the not deinit of PCIe when bootm is called. Reset the PCIe before init anyway to fix this U-Boot bug.

[ Upstream commit 16270a92355722e387e9ca19627c5a4d7bae1354 ] The current check will result in the multiple function device fails to initialize. So fix the check by masking out the multiple function bit.

PCI: Set bridge map_irq and swizzle_irq to default functions

2020-08-04T15:36:30+00:00

The majority of DT based host drivers use the default .map_irq() and .swizzle_irq() functions, so let's initialize the function pointers to the default and drop setting them in the host drivers. Drivers like iProc which don't support legacy interrupts need to set .map_irq() back to NULL.
