Subject: [PATCH v3 3/4] media: qcom: camss: Drop top_ahb/ahb/axi from QCM2290 subdevice clocks
Date: Thu, 30 Jul 2026 11:24:11 +0200 [thread overview]
Message-ID: <20260730-camss-version-v3-3-74a87302dd9f@oss.qualcomm.com> (raw)
In-Reply-To: <20260730-camss-version-v3-0-74a87302dd9f@oss.qualcomm.com>
Remove the top_ahb, ahb and axi clocks from QCM2290 subdevice clock
lists. These clocks are now handled centrally as global CAMSS PM clocks
and are automatically enabled when CAMSS is runtime resumed.
This avoids redundant clock references in individual subdevices and
ensures consistent clock management across the CAMSS pipeline.
