Subject: [PATCH v5 0/2] Add WDT driver for Toshiba Visconti ARM SoC
Date: Mon, 5 Oct 2020 11:30:10 +0900 [thread overview]
Message-ID: <20201005023012.603026-1-nobuhiro1.iwamatsu@toshiba.co.jp> (raw)
Hi,
This is the WDT driver for Toshiba's ARM SoC, Visconti[0].
This has not yet been included in Linux kernel, but patches have been posted [1]
and some patches have been applied [2].
Since this is a SoC driver, this cannot work by itself, but I have confirmed that it
works with the patch series sent as [1] with DT setting.
Best regards,
Nobuhiro
