As it was discussed earlier, 'pci-' prefix is more proper. > 4 files changed, 457 insertions(+) > create mode 100644 Documentation/devicetree/bindings/pci/ti-pci.txt > create mode 100644 drivers/pci/host/pcie-dra7xx.c [.....] > --- /dev/null > +++ b/drivers/pci/host/pcie-dra7xx.c [.....] > +#define PCIECTRL_TI_CONF_IRQSTATUS_MAIN 0x0024 > +#define PCIECTRL_TI_CONF_IRQENABLE_SET_MAIN 0x0028 I don't think that it's good to add vendor names such as TI to SFR names. How about adding 'DRA7XX' or just removing 'TI'? 1. PCIECTRL_DRA7XX_CONF_IRQSTATUS_MAIN 2.

Others look good.
