-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.
