Subject: [PATCH] ARM: dts: at91: sama5d29_curiosity: Add device tree for sama5d29_curiosity board
Date:   Fri, 4 Aug 2023 13:10:43 +0300
Message-ID: <20230804101043.4063-1-mihai.sain@microchip.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Content-Type: text/plain
Precedence: bulk

Add initial device tree file for sama5d29_curiosity board.

Changes in v2:
* drop dt-bindings patch
* remove vdd_1v8 regulator
* fix flx4 node to use 1 spi node and pinctrl
* add i2s0 node and pinctrl
* remove macb0 node and pinctrl
* remove unused pinctrl
* sort in alphabetical order all nodes and pinctrl
* replace "_" with "-" in node names
