[ath9k-devel] [PATCH v8 0/3] add devicetree support to ath9k

[Martin Blumenstingl <martin.blumenstingl@googlemail.com>]

This series adds support for configuring ath9k based devices via
devicetree. This was tested on PCI(e) based devices. This should work
for AHB based devices as well (adding more AHB specific properties may
still be needed) as soon as the ath79 platform is ready to populate the
ath9k wmac via devicetree.

Changes since v7:
- renamed node in the example (use wifi at ... instead of ath9k at ...), thanks
  Rob Herring for the hint
- added the QCA PCI vendor ID and a list of PCI IDs with the corresponding
  chipsets. This documents all known PCI IDs, but some device IDs are used
  by multiple chipsets the list of chipset(s) per device ID may be
  incomplete. Also some chipsets seem to use multiple PCI device IDs, such
  as AR9485 as documented here: https://wiki.debian.org/ath9k


Changes since v6:
- updated documentation to reflect that "reg" is a mandatory attribute
- dropped "qca,clk-25mhz" as it is only useful for AHB devices. OF
  support for AHB devices needs more work, so we can still introduce it
  later
- removed qca,disable-2ghz and qca,disable-5ghz as these will be
  introduced as generic bindings in a separate series


Changes since v5:
- updated the example in the documentation (keeping it at a bare
  minimum: removed the PCI bridge, use a better real-world example with
  less-confusing device/fn numbers, added the actual size of the config
  space to the reg property)
