Ilya Lipnitskiy 8dfd7329ad MIPS: pci-legacy: stop using of_pci_range_to_resource ... [ Upstream commit 3ecb9dc1581eebecaee56decac70e35365260866 ] Mirror commit aeba3731b1 ("powerpc/pci: Fix IO space breakage after of_pci_range_to_resource() change"). Most MIPS platforms do not define PCI_IOBASE, nor implement pci_address_to_pio(). Moreover, IO_SPACE_LIMIT is 0xffff for most MIPS platforms. of_pci_range_to_resource passes the _start address_ of the IO range into pci_address_to_pio, which then checks it against IO_SPACE_LIMIT and fails, because for MIPS platforms that use pci-legacy (pci-lantiq, pci-rt3883, pci-mt7620), IO ranges start much higher than 0xffff. In fact, pci-mt7621 in staging already works around this problem, see commit 09dd629eea ("staging: mt7621-pci: fix io space and properly set resource limits") So just stop using of_pci_range_to_resource, which does not work for MIPS. Fixes PCI errors like: pci_bus 0000:00: root bus resource [io 0xffffffff] Fixes: 0b0b0893d4 ("of/pci: Fix the conversion of IO ranges into IO resources") Signed-off-by: Ilya Lipnitskiy <ilya.lipnitskiy@gmail.com> Cc: Liviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Sasha Levin <sashal@kernel.org>		2021-05-14 09:50:39 +02:00
