Subject: [PATCH v2 0/3] remoteproc sysfs fixes/improvements
Date: Fri, 20 Nov 2020 21:01:53 -0600 [thread overview]
Message-ID: <20201121030156.22857-1-s-anna@ti.com> (raw)
Hi All,
This is a refresh of the unaccepted patches from an old series [1].
Patches 2 and 3 from that series were merged and these are rebased and
revised versions of the same patches. I had forgotten about these patches,
and am resurrecting these again. Patches are on top of latest 5.10-rc4.
The features being introduced here will be needed by the recently posted PRU
remoteproc driver [2] in addition to the existing Wkup M3 remoteproc driver.
Both of these drivers follow a client-driven boot methodology, with the latter
strictly booted by another driver in kernel. The PRU remoteproc driver will be
supporting both in-kernel clients as well as control from userspace orthogonally.
The logic though is applicable and useful to any remoteproc driver not using
'auto-boot' and using an external driver/application to boot the remoteproc.
regards
Suman
