Subject: arm: boot: beaglex15: pass correct interrupt
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0331966df0a288236bea6489420a35a0ca1e9043;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

arm: boot: beaglex15: pass correct interrupt

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.
