Subject: [U-Boot] [RFC PATCH 0/4 v1] Use fdt to init mvrtc driver for dreamplug
Date: Thu, 15 Sep 2011 13:54:30 +0000 [thread overview]
Message-ID: <cover.1316092940.git.u-boot@lakedaemon.net> (raw)
In-Reply-To: <1315865067-1443-1-git-send-email-sjg@chromium.org>
Simon, All,
This patch series is my attempt to learn device tree with a driver I'm
familiar with. Also, to create a real, working example for fdt in U-boot.
To make this work, I applied v2 of Simon Glass' patch series (what this
email is in reply to) against v2011.09-rc1. I then cherry picked my
dreamplug board support patch. Last, I applied the following series.
It works, although with CONFIG_OF_EMBED. I haven't tried _SEPARATE yet.
Some thoughts:
1.) 'kirkwood-dreamplug.dts' can be renamed 'dreamplug.dts'. Due to
machine_is_XXX 'dreamplug' will be unique, concise, and descriptive.
This requires changes to Simon Glass' patchset.
2.) The fdt files should be moved up one directory level, in the end, it
should look like:
board/Marvell/armada100-dt.c
board/Marvell/armada100-dt.h
board/Marvell/armada100.dtsi
board/Marvell/dreamplug.dts
board/Marvell/gplugd.dts # this includes armada100.dtsi
board/Marvell/guruplug.dts
board/Marvell/kirkwood.dtsi
board/Marvell/kirkwood-dt.c
board/Marvell/kirkwood-dt.h
board/Marvell/openrd.dts
board/Marvell/sheevaplug.dts
...
board/Marvell/<other boards>.dts
This also requires changes to Simon's patchset.
3.) Since mach names (dreamplug) and SoC names (kirkwood) are unique,
should we put all .dts and .dtsi files in one dir? eg /dts ? This
would facilitate migration to Grant Likely's device-tree.git
whereever and whenever it lands. This is also similar to how Linux
currently does it (arch/arm/boot/dts/)
Jason Cooper (4):
fdt: remove i2c example code.
fdt_decode: make more available.
mvrtc: add fdt support.
dreamplug: enable fdt
