+Subject: ARM: dts: dra7-evm: Make VDDA_1V8_PHY supply always on
+
+From: Roger Quadros <rogerq@ti.com>
+
+commit e120fb459693bbc1ac3eabdd65c3659d7cfbfd2a upstream.
+
+After clarification from the hardware team it was found that
+this 1.8V PHY supply can't be switched OFF when SoC is Active.
+
+Since the PHY IPs don't contain isolation logic built in the design to
+allow the power rail to be switched off, there is a very high risk
+of IP reliability and additional leakage paths which can result in
+additional power consumption.
+
+The only scenario where this rail can be switched off is part of Power on
+reset sequencing, but it needs to be kept always-on during operation.
+
+This patch is required for proper functionality of USB, SATA
+and PCIe on DRA7-evm.

+Subject: staging: vt6655: Fix Warning on boot handle_irq_event_percpu.
+
+From: Malcolm Priestley <tvboxspy@gmail.com>
+
+commit 6cff1f6ad4c615319c1a146b2aa0af1043c5e9f5 upstream.

+WARNING: CPU: 0 PID: 929 at /home/apw/COD/linux/kernel/irq/handle.c:147 handle_irq_event_percpu+0x1d1/0x1e0()
+irq 17 handler device_intr+0x0/0xa80 [vt6655_stage] enabled interrupts
+
+Using spin_lock_irqsave appears to fix this.
