of: address: Fix address translation when address-size is greater than 2

2023-11-28T17:19:39Z

[ Upstream commit 42604f8eb7ba04b589375049cc76282dad4677d2 ] With the recent addition of of_pci_prop_ranges() in commit 407d1a51921e ("PCI: Create device tree node for bridge"), the ranges property can have a 3 cells child address, a 3 cells parent address and a 2 cells child size. A range item property for a PCI device is filled as follow: 0 0 <-- Child --> <-- Parent (PCI definition) --> <- BAR size (64bit) --> This allow to translate BAR addresses from the DT. For instance: pci@0,0 { #address-cells = <0x03>; #size-cells = <0x02>; device_type = "pci"; compatible = "pci11ab,100", "pciclass,060400", "pciclass,0604"; ranges = <0x82000000 0x00 0xe8000000 0x82000000 0x00 0xe8000000 0x00 0x4400000>; ... dev@0,0 { #address-cells = <0x03>; #size-cells = <0x02>; compatible = "pci1055,9660", "pciclass,020000", "pciclass,0200"; /* Translations for BAR0 to BAR5 */ ranges = <0x00 0x00 0x00 0x82010000 0x00 0xe8000000 0x00 0x2000000 0x01 0x00 0x00 0x82010000 0x00 0xea000000 0x00 0x1000000 0x02 0x00 0x00 0x82010000 0x00 0xeb000000 0x00 0x800000 0x03 0x00 0x00 0x82010000 0x00 0xeb800000 0x00 0x800000 0x04 0x00 0x00 0x82010000 0x00 0xec000000 0x00 0x20000 0x05 0x00 0x00 0x82010000 0x00 0xec020000 0x00 0x2000>; ... pci-ep-bus@0 { #address-cells = <0x01>; #size-cells = <0x01>; compatible = "simple-bus"; /* Translate 0xe2000000 to BAR0 and 0xe0000000 to BAR1 */ ranges = <0xe2000000 0x00 0x00 0x00 0x2000000 0xe0000000 0x01 0x00 0x00 0x1000000>; ... }; }; }; During the translation process, the "default-flags" map() function is used to select the matching item in the ranges table and determine the address offset from this matching item. This map() function simply calls of_read_number() and when address-size is greater than 2, the map() function skips the extra high address part (ie part over 64bit). This lead to a wrong matching item and a wrong offset computation. Also during the translation itself, the extra high part related to the parent address is not present in the translated address. Fix the "default-flags" map() and translate() in order to take into account the child extra high address part in map() and the parent extra high address part in translate() and so having a correct address translation for ranges patterns such as the one given in the example above.

of: dynamic: Fix potential memory leak in of_changeset_action()

2023-09-11T14:58:54Z

Smatch complains that the error path where "action" is invalid leaks the "ce" allocation: drivers/of/dynamic.c:935 of_changeset_action() warn: possible memory leak of 'ce' Fix this by doing the validation before the allocation. Note that there is not any actual problem with upstream kernels. All callers of of_changeset_action() are static inlines with fixed action values.

of: unittest: Fix of_unittest_pci_node() kconfig dependencies

of_unittest_pci_node test depends on both CONFIG_PCI_DYNAMIC_OF_NODES and CONFIG_OF_OVERLAY. Move the test into the existing CONFIG_OF_OVERLAY ifdef and rework the CONFIG_PCI_DYNAMIC_OF_NODES dependency to use IS_ENABLED() instead. This reduces the combinations to build.
