Hi all, This is a bug fix submission of the v1 posted here [1]. The discussion on how to represent the wakeup-parent interrupt controller is on-going [2] here. The reiew comments in [1], from Doug and Stephen are addressed in this patch. The series attempts to add GPIO chip in hierarchy with PDC interrupt controller that can detect and wakeup the GPIOs routed to it, when the system is suspend/deep sleep mode. Changes in v2: - Fix bug related to unmasking PDC interrupt - Address review comments from Doug and Stepehn - Rebase on top of 5.0-rc2 - Fix signed-off-by tags - Enable QCOM_PDC in defconfig Do note that this patch uses the register address convention updated by Bjorn per [3].
