+Subject: [PATCH] brcmfmac: always print error when PSM's watchdog fires
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+So far we were attaching BRCMF_E_PSM_WATCHDOG event listener in
+brcmf_debug_attach which gets compiled only with CONFIG_BRCMDBG. This
+event means something went wrong and firmware / hardware usually can't
+be expected to work (reliably).
+
+Such a problem is significant for user experience so I believe we should
+print an error unconditionally (even with debugging disabled). What can
+be indeed optional is dumping bus memory as this is clearly part of
+debugging process.
+
+In the future we may also try to extend this listener by trying to
+recover from the error or at least signal it to the cfg80211.

+Using pr_err for things which are not errors is a bad idea. E.g. it

+console so that the user can see the error, which is not what we
+normally want to happen.
+
+Instead add a new brcmf_info macro and use that.

+
+If a scan gets aborted BRCMF_SCAN_STATUS_BUSY gets cleared in
+cfg->scan_status and when we receive an abort event from the firmware
+the BRCMF_SCAN_STATUS_BUSY check in the cfg80211_escan_handler will
+trigger resulting in multiple errors getting logged.
+
+Check for a status of BRCMF_E_STATUS_ABORT and in this case simply
+cleanly exit the cfg80211_escan_handler. This also avoids a
+BRCMF_E_STATUS_ABORT event arriving after a new scan has been started
+causing the new scan to complete prematurely without any data.

+Subject: [PATCH] brcmfmac: properly align buffers on certain platforms with 64
+ bit DMA
+
+Systems with 64 bit DMA at least partially require buffers to be used
+for DMA to be 8-byte-aligned. One example is Amlogic Meson GX.
+Switching the MMC/SDIO driver for this platform to SG DMA mode
+resulted in problems due to unaligned buffers.
+
+Fortunately the brcmfmac driver has a global define for the alignment.
+Changing it to 8 fixed the issues with Meson GX.

+
+Assure the event data buffer is long enough to hold the array
+of netinfo items and that SSID length does not exceed the maximum
+of 32 characters as per 802.11 spec.

+This patch also removes some boiler plate header size

+Subject: [PATCH] brcmfmac: fix alignment configuration on host using 64-bit
+ DMA
+
+For SDIO the alignment requirement for transfers from device to host
+is configured in firmware. This configuration is limited to minimum
+of 4-byte alignment. However, this is not correct for platforms using
+64-bit DMA when the minimum alignment should be 8 bytes. This issue
+appeared when the ALIGNMENT definition was set according the DMA
+configuration. The configuration in firmware was not using that macro
+defintion, but a hardcoded value of 4. Hence the driver reported
+alignment failures for data coming from the device and causing
+transfers to fail.
+
+Fixes: 6e84ab604bde ("brcmfmac: properly align buffers on certain platforms
