Subject: [PATCH v8 5/6] ARM: dts: tegra: add Tegra20 NAND flash controller node
Date: Sun, 24 Jun 2018 23:27:26 +0200 [thread overview]
Message-ID: <20180624212727.21672-6-stefan@agner.ch> (raw)
In-Reply-To: <20180624212727.21672-1-stefan@agner.ch>
From: Lucas Stach <dev@lynxeye.de>
Add basic controller device tree node to be extended by
individual boards. Use the assigned-clocks mechanism to set
NDFLASH clock to a sensible default rate of 150MHz.
