of/irq: Make of_msi_map_rid() PCI bus agnostic

2020-07-28T14:51:32+00:00

There is nothing PCI bus specific in the of_msi_map_rid()
implementation other than the requester ID tag for the input
ID space. Rename requester ID to a more generic ID so that
the translation code can be used by all busses that require
input/output ID translations.

No functional change intended.

of/irq: make of_msi_map_get_device_domain() bus agnostic

2020-07-28T14:51:32+00:00

of_msi_map_get_device_domain() is PCI specific but it need not be and
can be easily changed to be bus agnostic in order to be used by other
busses by adding an IRQ domain bus token as an input parameter.

of/iommu: Make of_map_rid() PCI agnostic

2020-07-28T14:51:31+00:00

There is nothing PCI specific (other than the RID - requester ID)
in the of_map_rid() implementation, so the same function can be
reused for input/output IDs mapping for other busses just as well.

Rename the RID instances/names to a generic "id" tag.

No functionality change intended.

of: irq: Remove WARN_ON() for kzalloc() failure

2019-05-02T21:38:00+00:00

There is no need to print a backtrace if kzalloc() fails, as the memory
allocation core already takes care of that.

iommu/of: make of_pci_map_rid() available for other devices too

2018-09-25T07:47:52+00:00

iommu-map property is also used by devices with fsl-mc. This
patch moves the of_pci_map_rid to generic location, so that it
can be used by other busses too.

'of_pci_map_rid' is renamed here to 'of_map_rid' and there is no
functional change done in the API.

Merge tag 'devicetree-for-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

2017-09-07T21:43:33+00:00

Pull DeviceTree updates from Rob Herring:
 "There's a few orphans in the conversion to %pOF printf specifiers
  included here that no one else picked up.

  Summary:

   - Convert more DT code to use of_property_read_* API.

   - Improve DT overlay support when adding multiple overlays

   - Convert printk's to %pOF format specifiers. Most went via subsystem
     trees, but picked up the remaining orphans

   - Correct unittests to use preferred "okay" for "status" property
     value

   - Add a KASLR seed property

   - Vendor prefixes for Mellanox, Theobroma System, Adaptrum, Moxa

   - Fix modalias buffer handling

   - Clean-up of include paths for building dtbs

   - Add bindings for amc6821, isl1208, tsl2x7x, srf02, and srf10
     devices

   - Add nvmem bindings for MediaTek MT7623 and MT7622 SoC

   - Add compatible string for Allwinner H5 Mali-450 GPU

   - Fix links to old OpenFirmware docs with new mirror on
     devicetree.org

   - Remove status property from binding doc examples"

of/irq: use of_property_read_u32_index to parse interrupts property

2017-08-01T17:24:06+00:00

Convert the interrupts property parsing to use the OF property API
instead of open coding the parsing of the raw property value. This saves
a number of LoC, and the result is easier to read.
