+Subject: [PATCH] arm64: dts: apple: ipad5: Wake from sleep on the Smart Cover
+
+PMIC GPIO lines 0 and 10 are the Smart Cover hall sensors. Their events,
+0x30 and 0x3a, latch while the iPad sleeps; list them as wake-only so
+that opening the cover wakes the iPad. The polled switches are
+unchanged: lines 0 and 10 are already outside gpio-reserved-ranges.
+
+[Orchard: from orchard PR #118, commit e8b5e4b7; moved from the J71t
+ board file to the shared iPad 5 file, so every iPad 5 model has it]

+Subject: [PATCH] arm64: dts: apple: ipad6: Add the Smart Cover
+
+The iPad 6 has the iPad 5's Smart Cover hall sensors on the same PMIC
+lines: Apple's device tree for both boards names PMIC GPIO 0
+"halleffect" and GPIO 10 "halleffect1" (/arm-io/i2c0/pmu event names,
+/buttons function-button_halleffect{,1} with the same flags). Describe
+them as on the iPad 5: two polled SW_MACHINE_COVER switches,
+the two lines taken out of the reserved ranges, and their events 0x30
+and 0x3a as wake-only, so that opening the cover wakes the iPad.
+
+Measured on a J71b by reading the PMIC input register (0x186): both
+lines read 1 with the cover open and 0 with it closed, so the assumed
+active-low polarity is right.

+Subject: [PATCH] dt-bindings: gpio: apple,d2365-pmic-gpio: Describe wake-only
+ events
+
+Add apple,wake-events: GPIO events (0x30 plus the line) that end system
+sleep and have no interrupt consumer, such as the iPad Smart Cover hall
+sensors on lines 0 and 10. A hall sensor that is unmasked while the
+system is awake drives the PMU line on every change of the magnet field,
+so these events are unmasked only for the duration of a sleep and cannot
+be mapped as interrupts. Only the D2365 has the event controller they
+need.
