Hi Tony,
I tried Branch [1] above. AM335x-boneblack is doing all good with ds0.
AM437x-gp the following is happening:
https://pastebin.ubuntu.com/p/fmZNYgJ9Sp/
There seems to be a timeout due to which resume is not immediate i see
1-2s delay and i see i2c timeout.
[ 402.247271] omap_i2c 4802a000.i2c: controller timed out
[ 402.247441] pixcir_ts 1-005c: pixcir_int_enable: can't read reg 0x34
: -110
[ 402.247486] pixcir_ts 1-005c: Failed to disable interrupt generation:
-110
[ 402.247522] pixcir_ts 1-005c: Failed to stop
[ 402.247607] dpm_run_callback(): pixcir_i2c_ts_resume+0x0/0x98
[pixcir_i2c_ts] returns -110
so pixcir_i2c_ts_resume is retuning -110 which is timeout error code.
I did some touch screen testing after DS0 resume seems to be working.
Everything is in pastebin link provided above.

Keerthy
