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.
