* 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".
|
|
Optional properties:
|
- reg: Address and length of the register set for the device.
|
- reg-names: Must include the list of following reg names,
|
"membase"
|
- 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".
|
- interrupts: List of interrupt lines. Must contain an entry
|
for each entry in the interrupt-names property.
|
- interrupt-names: Must include the entries for MSI interrupt
|
names ("msi0" to "msi15") and legacy interrupt
|
name ("legacy"),
|
- 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" is "vdd-0.8-cx-mx".
|
|
Example (to supply the calibration data alone):
|
|
In this example, the node is defined as child node of the PCI controller.
