Subject: [PATCH 2/3] clk: rockchip: add watchdog pclk on rk3328
Date: Sat, 15 Jun 2019 17:30:31 +0200 [thread overview]
Message-ID: <20190615153032.27772-2-heiko@sntech.de> (raw)
In-Reply-To: <20190615153032.27772-1-heiko@sntech.de>
The watchdog pclk is controlled from the secure GRF but we still
want to mention it explicitly to not use arbitary parent clocks
in the devicetree wdt node, so add a SGRF_GATE for it.
