Hmm, here you say that IRQ_TYPE_LEVEL_HIGH, so it is level interrupts,
but the driver overrides to rising edge unconditionally. Since you are
the first to add DT support please make separate patch to driver to drop
the ORQ trigger from request_theraded_irq() leaving only IRQF_ONESHOT.

Also please create patch removing platform data support as noone is
using it upstream.

What about the rest of config parameters from bma150_cfg? They should be
handled as device properties too.

Thanks.
