As part of suspend to RAM, tsens hardware will be turned off and it

suspend to RAM due to tsens interrupts since system is already going

power state. Hence disabling tsens interrupt during suspend to RAM

Is that a hardware limitation, or a software design choice? I'm not
sure I want my phone to have thermal notifications disabled when
it's suspended.


As part of suspend to RAM , entire SOC will be off, this mode (suspend
to RAM) is not intended for Mobile product. Tsens interrupts are not
disabled as part of suspend to idle(suspend mode for mobile).

You should hide the callbacks behind the CONFIG_SUSPEND Kconfig option
so that it only gets enabled when S2R is enabled.

Yes i will take care of this in next version.
