Subject: [PATCH v8 18/20] remoteproc: k3: Refactor mem_release() functions into common driver
Date: Fri, 3 Jan 2025 15:42:29 +0530 [thread overview]
Message-ID: <20250103101231.1508151-19-b-padhi@ti.com> (raw)
In-Reply-To: <20250103101231.1508151-1-b-padhi@ti.com>
The k3_dsp_mem_release() and k3_m4_rproc_dev_mem_release() functions
release the reserved memory of the device, which get auto triggered upon
device removal. Refactor these functions into ti_k3_common.c driver as
k3_mem_release() and align DSP and M4 drivers to use this common
function throughout.
