From mboxrd@z Thu Jan 1 00:00:00 1970 From: Benjamin Herrenschmidt Date: Fri, 29 Jun 2018 13:51:06 +1000 Subject: [PATCH 7/7] arm: dts: aspeed: Enable vhub on port A of AST2500 EVB In-Reply-To: <20180629035106.27181-1-benh@kernel.crashing.org> References: <20180629035106.27181-1-benh@kernel.crashing.org> Message-ID: <20180629035106.27181-8-benh@kernel.crashing.org> List-Id: To: linux-aspeed@lists.ozlabs.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit This is an eval board, it makes sense to enable many functions by default. This changes the device-tree to set port A to be a USB device and leave port B as a host, along with a little comment explaining how to change it. (the vhub device can only exist on port A on this SoC) Signed-off-by: Benjamin Herrenschmidt --- arch/arm/boot/dts/aspeed-ast2500-evb.dts | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/aspeed-ast2500-evb.dts b/arch/arm/boot/dts/aspeed-ast2500-evb.dts index 2bff1b253842..2375449c02d0 100644 --- a/arch/arm/boot/dts/aspeed-ast2500-evb.dts +++ b/arch/arm/boot/dts/aspeed-ast2500-evb.dts @@ -80,7 +80,13 @@ }; }; -&ehci0 { +/* + * Enable port A as device (via the virtual hub) and port B as + * host by default on the eval board.
