+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: Revert "mac80211: move "bufferable MMPDU" check to fix AP mode scan"
+
+From: Johannes Berg <johannes.berg@intel.com>
+
+commit 08b9939997df30e42a228e1ecb97f99e9c8ea84e upstream.
+
+This reverts commit 277d916fc2e959c3f106904116bb4f7b1148d47a as it was
+at least breaking iwlwifi by setting the IEEE80211_TX_CTL_NO_PS_BUFFER
+flag in all kinds of interface modes, not only for AP mode where it is
+appropriate.
+
+To avoid reintroducing the original problem, explicitly check for probe
+request frames in the multicast buffering code.
+
