Subject: [PATCH] ARM: dts: at91: sama5d2 Xplained: Correct the macb irq pinctrl node
Date: Tue, 1 Mar 2016 10:48:05 +0100	[thread overview]
Message-ID: <56D56555.1030703@atmel.com> (raw)
In-Reply-To: <1455790866-13301-1-git-send-email-romain.izard.pro@gmail.com>

Le 18/02/2016 11:21, Romain Izard a ?crit :
> All pinctrl nodes for the Atmel pinctrl controller need to have their
> bias configuration explicitly defined. Otherwise, the pinctrl mapping
> is not valid.
> 
> It works for now as the pinctrl driver proceeds even with invalid
> mappings, but this can become an issue, if the pinctrl driver starts
> to require valid mappings. Additionally, the pin is not protected from
> being remapped later by an other driver.
> 
> There is an external 1k? pull-up to 3.3V, so no bias is required on
> the Ethernet PHY's interrupt line.

Acked-by: Nicolas Ferre <nicolas.ferre@atmel•com>
