Subject: [PATCH v11 2/6] remoteproc: pru: Add enum for PRU Core Identifiers.
Date: Wed, 7 Dec 2022 16:34:07 +0530	[thread overview]
Message-ID: <20221207110411.441692-3-danishanwar@ti.com> (raw)
In-Reply-To: <20221207110411.441692-1-danishanwar@ti.com>

Introducing enum pruss_pru_id for PRU Core Identifiers.
PRUSS_PRU0 indicates PRU Core 0.
PRUSS_PRU1 indicates PRU Core 1.
PRUSS_NUM_PRUS indicates the total number of PRU Cores.
