Subject: [RFC PATCH v2 07/11] interconnect: Relax condition in
apply_constraints()
From: Artur Świgoń <a.swigon@...tner.samsung.com>
The exynos-bus devfreq driver is extended with interconnect functionality
by a subsequent patch. This patch removes a check from the interconnect
framework that prevents interconnect from working on exynos-bus, in which
every bus is a separate interconnect provider.
