Subject: [PATCH 3/6] irqdomain: Export of_phandle_args_to_fwspec()
Date: Thu, 25 Mar 2021 14:30:23 +0530 [thread overview]
Message-ID: <20210325090026.8843-4-kishon@ti.com> (raw)
In-Reply-To: <20210325090026.8843-1-kishon@ti.com>
Export of_phandle_args_to_fwspec() to be used by drivers.
of_phandle_args_to_fwspec() can be used by drivers to get irq specifier
from device node useful while creating hierarchy domain. This was
suggested by Marc Zyngier [1].
