Subject: [U-Boot] [PATCH 4/6] ARM: dts: at91: Add dts files for at91sam9260ek/9g20ek
Date: Wed, 12 Apr 2017 16:12:01 +0800 [thread overview]
Message-ID: <20170412081203.12303-5-wenyou.yang@atmel.com> (raw)
In-Reply-To: <20170412081203.12303-1-wenyou.yang@atmel.com>
The device tree source files of at91sam9g20ek and at91sam9260ek
boards are copied from the Linux v4.10, do the changes below.
- Fix the build error for the usb0 node.
- Add the reg property for the pinctrl node.
- Move the gpio (pioA, pioB, pioC ...) nodes as the pinctrl's
slibling nodes, instead of the child nodes.
- Add the "u-boot,dm-pre-reloc" property for the dbgu node are used
in board_init_f stage.
- Add the clk pinctrl of the mmc0 node.
- Fix the compilation warnings.
