+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:
+
+[  109.102097] ath10k_ahb a000000.wifi: boot coex_support 1 coex_gpio_pin 52
