Subject: [PATCH 2/2] arm: boot: beaglex15: pass correct interrupt
Date: Thu, 12 Nov 2015 11:53:01 -0600 [thread overview]
Message-ID: <1447350781-20649-3-git-send-email-balbi@ti.com> (raw)
In-Reply-To: <1447350781-20649-1-git-send-email-balbi@ti.com>
According to latest schematics [1], GPIO_1/VBUSDET
on TPS659038 is tied to AM57x GPIO4_21. We can use
that as a VBUS interrupt, instead of relying on
PMIC's VBUS interrupts which don't seem to be firing
on x15 at all.
A follow up patch will add support for using this
GPIO-based interrupt mechanism for notifying about
VBUS.
