+Subject: [PATCH] brcmfmac: Keep OOB wake-interrupt disabled when it shouldn't
+ be enabled
+
+NVIDIA Tegra SoCs do not like when OOB wake is enabled and WiFi interface
+is in DOWN state during suspend. This results in a CPU hang on programming
+OOB wake-up state of the GPIO controller during of system's suspend.
+
+The solution is trivial: don't enable wake for the OOB interrupt when it
+should be disabled.
+
+This fixes hang on Tegra20 (Acer A500) and Tegra30 (Nexus 7) devices which
+are using BCM4329 and BCM4330 WiFi chips respectively.

+Subject: [PATCH] brcmfmac: sdio: Fix OOB interrupt initialization on brcm43362
+
+Commit 262f2b53f679 ("brcmfmac: call brcmf_attach() just before calling
+brcmf_bus_started()") changed the initialization order of the brcmfmac
+SDIO driver. Unfortunately since brcmf_sdiod_intr_register() is now
+called before the sdiodev->bus_if initialization, it reads the wrong
+chip ID and fails to initialize the GPIO on brcm43362. Thus the chip
+cannot send interrupts and fails to probe:
+
+[ 12.517023] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout
+[ 12.531214] ieee80211 phy0: brcmf_bus_started: failed: -110
+[ 12.536976] ieee80211 phy0: brcmf_attach: dongle is not responding: err=-110
+[ 12.566467] brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed
+
+Initialize the bus interface earlier to ensure that
+brcmf_sdiod_intr_register() properly sets up the OOB interrupt.
