Subject: [PATCH v2 2/2] drm/msm: Fix duplicate gpu node in icc summary
Date: Wed, 28 Oct 2020 20:05:11 +0530 [thread overview]
Message-ID: <1603895711-23755-2-git-send-email-akhilpo@codeaurora.org> (raw)
In-Reply-To: <1603895711-23755-1-git-send-email-akhilpo@codeaurora.org>
The dev_pm_opp_of_add_table() api initializes the icc nodes for gpu
indirectly. So we can avoid using of_icc_get() api in the common
probe path. To improve this, move of_icc_get() to target specific code
where it is required.
This patch helps to fix duplicate gpu node listed in the interconnect
summary from the debugfs.
