[PATCH 2/3] clk: rockchip: add watchdog pclk on rk3328

From: Heiko Stuebner <heiko@sntech.de>
Date: 2019-06-15 15:30:48
Also in: linux-clk, linux-rockchip, lkml
Subsystem: arm/rockchip soc support, common clk framework, the rest · Maintainers: Heiko Stuebner, Michael Turquette, Stephen Boyd, Linus Torvalds

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.

Suggested-by: Leonidas P. Papadakos <redacted>
