Commit Message

Konrad Dybcio April 6, 2023, 12:59 a.m. UTC
Convert the ATH10K bindings to YAML.

Dropped properties that are absent at the current state of mainline:
- qcom,msi_addr
- qcom,msi_base

qcom,coexist-support and qcom,coexist-gpio-pin do very little and should
be reconsidered on the driver side, especially the latter one.

Somewhat based on the ath11k bindings.

-* Qualcomm Atheros ath10k wireless devices
-
-Required properties:
-- compatible: Should be one of the following:
-	* "qcom,ath10k"
-	* "qcom,ipq4019-wifi"
-	* "qcom,wcn3990-wifi"
-
-PCI based devices uses compatible string "qcom,ath10k" and takes calibration
-data along with board specific data via "qcom,ath10k-calibration-data".
-Rest of the properties are not applicable for PCI based devices.
-
-AHB based devices (i.e. ipq4019) uses compatible string "qcom,ipq4019-wifi"
-and also uses most of the properties defined in this doc (except
-"qcom,ath10k-calibration-data"). It uses "qcom,ath10k-pre-calibration-data"
-to carry pre calibration data.
-
-In general, entry "qcom,ath10k-pre-calibration-data" and
-"qcom,ath10k-calibration-data" conflict with each other and only one
-can be provided per device.
-
-SNOC based devices (i.e. wcn3990) uses compatible string "qcom,wcn3990-wifi".
-
-- reg: Address and length of the register set for the device.
-- reg-names: Must include the list of following reg names,
-	     "membase"
-- interrupts: reference to the list of 17 interrupt numbers for "qcom,ipq4019-wifi"
-	      compatible target.
-	      reference to the list of 12 interrupt numbers for "qcom,wcn3990-wifi"
-	      compatible target.
-	      Must contain interrupt-names property per entry for
-	      "qcom,ath10k", "qcom,ipq4019-wifi" compatible targets.
-
-- interrupt-names: Must include the entries for MSI interrupt
-		   names ("msi0" to "msi15") and legacy interrupt
-		   name ("legacy") for "qcom,ath10k", "qcom,ipq4019-wifi"

-				 as an array, the length can vary between
-				 hw versions.
-- qcom,ath10k-pre-calibration-data : pre calibration data as an array,
-				     the length can vary between hw versions.
-- <supply-name>-supply: handle to the regulator device tree node
-			   optional "supply-name" are "vdd-0.8-cx-mx",
-			   "vdd-1.8-xo", "vdd-1.3-rfa", "vdd-3.3-ch0",

-			 support by the hardware.
-- qcom,coexist-gpio-pin : gpio pin number  information to support coex
-			  which will be used by wifi firmware.

-* Subnodes
-The ath10k wifi node can contain one optional firmware subnode.
-Firmware subnode is needed when the platform does not have TustZone.
-The firmware subnode must have:
