Subject: [PATCH v3 1/2] remoteproc: imx_rproc: Allow setting of the mailbox transmit mode
Date: Thu, 22 Aug 2024 21:48:49 +0800	[thread overview]
Message-ID: <20240822-imx_rproc-v3-1-6d943723945d@nxp.com> (raw)
In-Reply-To: <20240822-imx_rproc-v3-0-6d943723945d@nxp.com>

From: Peng Fan <peng.fan@nxp.com>

Current mailbox is blocking by default, but there are cases where we don't
need to wait for a response.

Linux just needs to send data to the remote processor, so let's
allow tx_block mode to be set (true/false) depending on usecase.

No functional changes.
