pinctrl: qcom: Add intr_target_width field to support increased number of interrupt targets
SA8775 and newer target have added support for an increased number of
interrupt targets. To implement this change, the intr_target field, which
is used to configure the interrupt target in the interrupt configuration
register is increased from 3 bits to 4 bits.
In accordance to these updates, a new intr_target_width member is
introduced in msm_pingroup structure. This member stores the value of
width of intr_target field in the interrupt configuration register. This
value is used to dynamically calculate and generate mask for setting the
intr_target field. By default, this mask is set to 3 bit wide, to ensure
backward compatibility with the older targets.
