This replaces the existing .txt binding file. Furthermore, this
also helps with validating DTS files.
Introduced binding changes:
1. added inherited mac-address nvmem property
2. added inherited ieee80211-freq-limit property
3. added new calibration nvmem property
4. added second example (taken from the Netgear WNDR3700v2)
Reason: Setting qca,no-eeprom; takes presedence over
nvmem-cells. I think a different example is needed,
because the driver can only reads from one calibration
source per device.
5. (re-added) chip list (based on data from ath9k's pci.c)
Added binding .yaml to MAINTAINERS.

v1 -> v2:
- added second example (pci device - AR9220)
- added commented chip list from the qca,ath9k.txt+ath9k's pci.c
(I hope my changes didn't invalidate Rob's review there.
I did run "make dt_binding_check" and no warning/error
came up.)

-* Qualcomm Atheros ath9k wireless devices
-
-This node provides properties for configuring the ath9k wireless device. The
-node is expected to be specified as a child node of the PCI controller to
-which the wireless chip is connected.
-
-Required properties:
-- compatible: For PCI and PCIe devices this should be an identifier following
- the format as defined in "PCI Bus Binding to Open Firmware"
- Revision 2.1. One of the possible formats is "pciVVVV,DDDD"
- where VVVV is the PCI vendor ID and DDDD is PCI device ID.
- Typically QCA's PCI vendor ID 168c is used while the PCI device
- ID depends on the chipset - see the following (possibly
- incomplete) list:
- - 0023 for AR5416
- - 0024 for AR5418
- - 0027 for AR9160
- - 0029 for AR9220 and AR9223
- - 002a for AR9280 and AR9283
- - 002b for AR9285
- - 002c for AR2427
- - 002d for AR9227
- - 002e for AR9287
- - 0030 for AR9380, AR9381 and AR9382
- - 0032 for AR9485
- - 0033 for AR9580 and AR9590
- - 0034 for AR9462
- - 0036 for AR9565
- - 0037 for AR9485
-- reg: Address and length of the register set for the device.
-
-Optional properties:
-- qca,no-eeprom: Indicates that there is no physical EEPROM connected to the
- ath9k wireless chip (in this case the calibration /
- EEPROM data will be loaded from userspace using the
- kernel firmware loader).
-
-The MAC address will be determined using the optional properties defined in
-net/ethernet.txt.
-
-In this example, the node is defined as child node of the PCI controller:
-&pci0 {
- wifi@168c,002d {
- compatible = "pci168c,002d";
- reg = <0x7000 0 0 0 0x1000>;
- qca,no-eeprom;
- };
-};
