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 [1] https://patchwork.kernel.org/project/linux-remoteproc/cover/20180915003725.17549-1-s-anna@ti.com/ [2] https://patchwork.kernel.org/project/linux-remoteproc/cover/20201119140850.12268-1-grzegorz.jaszczyk@linaro.org/ Suman Anna (3): remoteproc: Fix unbalanced boot with sysfs for no auto-boot rprocs remoteproc: Introduce deny_sysfs_ops flag remoteproc: wkup_m3: Set deny_sysfs_ops flag drivers/remoteproc/remoteproc_sysfs.c | 28 ++++++++++++++++++++++++++- drivers/remoteproc/wkup_m3_rproc.c | 1 + include/linux/remoteproc.h | 2 ++ 3 files changed, 30 insertions(+), 1 deletion(-)
