Subject: [PATCH v2 5/5] remoteproc: switch drivers to optional resource-table helper
Date: Thu, 14 May 2026 09:21:29 -0700 [thread overview]
Message-ID: <20260514162129.1504162-6-ben.levinsky@amd.com> (raw)
In-Reply-To: <20260514162129.1504162-1-ben.levinsky@amd.com>
Use the shared optional resource-table helper in the remoteproc
drivers that already treat a missing resource table as non-fatal:
xlnx_r5_remoteproc, rcar_rproc, stm32_rproc, imx_rproc, and
imx_dsp_rproc.
Keep thin local parse_fw() wrappers in each driver so the helper only
centralizes the return-value handling. That lets each platform retain
control over whether the missing-table case is logged and at what
severity, while other parsing failures continue to propagate to the
caller.
