Subject: [PATCH 0/2] qcom_wdt bark irq support

Support pre-timeout when the bark irq is avaible.

This is the fifth version of the patchset addressing all the review
issues to date:

 v5:
    include linux/bits.h
    pretimeout only enables IRQs if value != 0
    remove unnecessary subtract operation
    add clarity to the conditional in the probe function
    revert the irq registration changes
        
 v4:
    remove unnecessary include and private variable
    provide macro for WDT EN register values
    use pretimeout as per its API intent
    handle EPROBE_DEFER on get_irq
    modify the irq registration as per pm8916_wdt
    
 v3
    remove unecessary variable from the driver's private storage
 
 v2:
     register the pre-timeout notifier.

With the second patch in the set, I took the oportunity to do some
cleanup in the same code base removing an unnecesary variable from the
driver's private storage.

Jorge Ramirez-Ortiz (2):
  watchdog: qcom: support pre-timeout when the bark irq is available
  watchdog: qcom: remove unnecessary variable from private storage
