Subject: [PATCH v4 2/3] interconnect: Relax requirement in of_icc_get_from_provider()
Date: Thu, 16 Jan 2020 15:42:01 +0100 [thread overview]
Message-ID: <20200116144202.12116-3-a.swigon@samsung.com> (raw)
In-Reply-To: <20200116144202.12116-1-a.swigon@samsung.com>
This patch relaxes the condition in of_icc_get_from_provider() so that
it is no longer required to set '#interconnect-cells' to <1> in the DT,
and therefore it is not required to supply dummy node IDs in the
'interconnects' property when node IDs are dynamically generated rather
than hardcoded (statically allocated).
In case of the devfreq driver for exynos-bus, node IDs are dynamically
allocated and '#interconnect-cells' is always zero.
