Subject: [PATCH 036/182] pinctrl: msm: Correct interrupt code for TLMM v2
|
|
|
|
Acking interrupts are done differently between on v2 and v3, so add an extra
|
|
attribute to the pingroup struct to let the platform definitions control this.
|
|
Also make sure to start dual edge detection by detecting the rising edge.
