The bus + bmi-chip-id + bmi-board-id is not enough to identify the correct board data file on QCA4019 based devices. Multiple different boards share the same values. Only the original reference designs can currently be identified and loaded from the board-2.bin. But these will not result in the correct calibration data when combined with the pre-calibration data from the device. An additional "variant" information has to be provided (via SMBIOS or DT) to select the correct board data for a design which was modified by an ODM.

* Qualcomm Atheros ath10k wireless devices
|
|
|
|
Required properties:
|
|
- compatible: Should be one of the following:
|
|
* "qcom,ath10k"
|
|
* "qcom,ipq4019-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.
|
|
|
|
Optional properties:
|
|
- reg: Address and length of the register set for the device.
|
|
- 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.
|
|
|
|
Example (to supply the calibration data alone):
|
|
|
|
In this example, the node is defined as child node of the PCI controller.
|
|
|
|
