+Subject: [PATCH] reset: ath79: read back reset register
+
+Read back the reset register in order to flush the cache. This fixes
+spurious reboot hangs on TP-Link TL-WDR3600 and TL-WDR4300 with Zentel
+DRAM chips.
+
+This issue was fixed in the past, but switching to the reset-driver
+specific implementation removed the old fix.
