Subject: [PATCH 4/5] arm64: dts: qcom: x1e80100: Add deepest idle state
Date: Thu, 12 Mar 2026 21:26:38 +0530	[thread overview]
Message-ID: <20260312-hamoa_pdc-v1-4-760c8593ce50@oss.qualcomm.com> (raw)
In-Reply-To: <20260312-hamoa_pdc-v1-0-760c8593ce50@oss.qualcomm.com>

Add deepest idle state along with pdc config reg to make GPIO IRQs work
as wakeup capable interrupts in deepest idle state.

Add QMP handle to allow PDC device to place a SoC level low power mode
restriction.
