[PATCH v3 1/2] dt-bindings: net: Convert ATH10K to YAML
From: Konrad Dybcio
Date: Thu Apr 06 2023 - 08:56:12 EST
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"
- compatible targets.
-
-Optional properties:
-- resets: Must contain an entry for each entry in reset-names.
- See ../reset/reseti.txt for details.
-- reset-names: Must include the list of following reset names,
- "wifi_cpu_init"
- "wifi_radio_srif"
- "wifi_radio_warm"
- "wifi_radio_cold"
- "wifi_core_warm"
- "wifi_core_cold"
-- clocks: List of clock specifiers, must contain an entry for each required
- entry in clock-names.
-- clock-names: Should contain the clock names "wifi_wcss_cmd", "wifi_wcss_ref",
- "wifi_wcss_rtc" for "qcom,ipq4019-wifi" compatible target and
- "cxo_ref_clk_pin" and optionally "qdss" for "qcom,wcn3990-wifi"
- compatible target.
-- qcom,msi_addr: MSI interrupt address.
-- qcom,msi_base: Base value to add before writing MSI data into
- MSI address register.
-- qcom,ath10k-calibration-variant: string to search for in the board-2.bin
- variant list with the same bus and device
- specific ids
-- qcom,ath10k-calibration-data : calibration data + board specific data
- 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",
- and "vdd-3.3-ch1".
-- memory-region:
- Usage: optional
- Value type: <phandle>
- Definition: reference to the reserved-memory for the msa region
- used by the wifi firmware running in Q6.
-- iommus:
- Usage: optional
- Value type: <prop-encoded-array>
- Definition: A list of phandle and IOMMU specifier pairs.
-- ext-fem-name:
- Usage: Optional
- Value type: string
- Definition: Name of external front end module used. Some valid FEM names
- for example: "microsemi-lx5586", "sky85703-11"
- and "sky85803" etc.
-- qcom,snoc-host-cap-8bit-quirk:
- Usage: Optional
- Value type: <empty>
- Definition: Quirk specifying that the firmware expects the 8bit version
- of the host capability QMI request
-- qcom,xo-cal-data: xo cal offset to be configured in xo trim register.
-
-- qcom,msa-fixed-perm: Boolean context flag to disable SCM call for statically
- mapped msa region.
-
-- qcom,coexist-support : should contain eithr "0" or "1" to indicate coex
- 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:
-
-- iommus:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: A list of phandle and IOMMU specifier pairs.
