Adjust our local ath10k-ct patches to the change
from the -ct 6.2 version to 6.4.
This restores e.g. the LED functionality.

Subject: [PATCH] ath10k: read qcom,coexist-support as a u32
|
|
|
|
Read qcom,coexist-support as a u32 instead of a u8
|
|
|
|
When we set the property to <1> in the DT (as specified in the doc),
|
|
"of_property_read_u8" read 0 instead of 1. This is because of the data format.
|
|
|
|
By default <1> is written with 32 bits.
|
|
The problem is that the driver is trying to read a u8.
|
|
|
|
The difference can be visualized using hexdump in a running device:
|
|
Default 32 bits output:
|
|
=======================
|
|
0000000 0000 0100
|
|
0000004
|
|
|
|
8 bits output:
|
|
==============
|
|
0000000 0001
|
|
0000001
|
|
|
|
By changing "of_property_read_u8" by "of_property_read_u32", the driver
|
|
is aligned with the documentation and is able to read the value without
|
|
modifying the DT.
|
|
|
|
The other solution would be to force the value in the DT to be saved as
|
|
an 8 bits value (qcom,coexist-support = /bits/ 8 <1>),
|
|
which is against the doc and less intuitive.
|
|
|
|
Validation:
|
|
===========
|
|
The patch was tested on a real device and we can see in the debug logs
|
|
that the feature is properly initialized:
