Subject: [PATCH v2 2/8] PM / devfreq: event: Find the instance of devfreq-event device by using phandle
Date: Fri, 15 Apr 2016 15:32:49 +0900 [thread overview]
Message-ID: <1460701975-24178-3-git-send-email-cw00.choi@samsung.com> (raw)
In-Reply-To: <1460701975-24178-1-git-send-email-cw00.choi@samsung.com>
This patch use the phandle to find the instance of devfreq-event device in
Device Tree when calling the devfreq_event_get_edev_by_phandle() because there
is two type devfreq-event devices as following:
First case, exynos-ppmu.c driver provides the maximum four event of each PPMU.
So, when getting the instance of devfreq-event device, using the unique name of
struct devfreq_event_desc.
Second case, exynos-nocp.c driver provide the only one event of each NoC Probe
device. So, when getting the instance of devfreq-event device, using the
phandle of each NoC probe device.
