Subject: [PATCH v3 6/6] remoteproc: pru: Add support for various PRU cores on K3 J721E SoCs
Date: Fri, 4 Dec 2020 21:18:07 +0100 [thread overview]
Message-ID: <20201204201807.14716-7-grzegorz.jaszczyk@linaro.org> (raw)
In-Reply-To: <20201204201807.14716-1-grzegorz.jaszczyk@linaro.org>
From: Suman Anna <s-anna@ti.com>
The K3 J721E family of SoCs have a revised version of the AM65x ICSSG IP
and contains two instances of this newer ICSSG IP. Each ICSSG processor
subsystem contains 2 primary PRU cores, 2 auxiliary PRU cores called RTUs,
and 2 new auxiliary cores called Transmit PRUs (Tx_PRUs).
Enhance the existing PRU remoteproc driver to support these new PRU
and RTU cores by using specific compatibles. The cores have the same
memory copying limitations as on AM65x, so reuses the custom memcpy
function within the driver's ELF loader implementation. The initial
names for the firmware images for each PRU core are retrieved from
DT nodes, and can be adjusted through sysfs if required.
