We keep telling you that your email threading is broken. It still is makes reviewers life more difficult. Maintainer as well as applying is not straightforward.
Why this is not improved?
Sorry for causing difficulties. Would you be so kind and tell me how to avoid threading broken? I get the threading broken issue every time, but I really have no idea of how to fix it.
Changes in v5:
- remove ti,broadcast-addr
- remove address-cells
- remove size-cells
- put compatible item first in properties
- change the maxItems of reg from 4 to 8
- remove white space around <>
- correct the reg format to <0x38>, <0x3a> etc
- remove '\t' in the file
- correct a comment in the example

Kindly point my mistake, I run the commands from the Documentation/devicetree/bindings/writing-schema.rst before submission. For dt_binding_check, command as follow, no issue reported, make DT_CHECKER_FLAGS=-m O= O=build_dir/x86 dt_binding_check -j $(expr $(nproc) - 1) 2>&1 | tee $OUTPUT_DIR1/$OUTPUT_DIR2/dt_binding_check.log …………… DTEX Documentation/devicetree/bindings/sound/samsung,tm2.example.dts DTEX Documentation/devicetree/bindings/sound/ti,tas2781.example.dts DTEX Documentation/devicetree/bindings/sound/amlogic,t9015.example.dts ……………..

As to “make dtbs_checktest”, it can’t work in default compiling system(x86) at all. In order to test the bindings, it was integrated into the BeagleBoneBlack compiling system.
