This series refactors a lot of functions & callbacks from ti_k3_dsp_remoteproc.c, ti_k3_r5_remoteproc.c and ti_k3_m4_remoteproc.c drivers. This is a consolidated and final series as part of the refactoring of K3 remoteproc drivers. Below is the breakdown: 1. PATCHES #1-#5 does the pre-cleanup and aligns R5, DSP, M4 data structures. 2. PATCHES #6-#8 fixes important bugs in R5 and DSP drivers before refactoring them into a common driver. 3. PATCHES #9-#26 does the actual refactoring from into ti_k3_common.c driver.
NOTE: This series supersedes below series: https://lore.kernel.org/all/20250219091042.263819-1-b-pa...@ti.com/ https://lore.kernel.org/all/20250103101231.1508151-1-b-pa...@ti.com/ https://lore.kernel.org/all/20250108063727.1416324-1-b-pa...@ti.com/ Testing Done: 1. Tested boot of R5Fs, C66x DSPs, C71x DSPs across Jacinto J7* devices in remoteproc mode and IPC-Only mode. 2. Tested boot of M4F core _only_ in _AM62xx SK_ board in Remoteproc mode and IPC-Only mode. 3. Tested Core stop and detach operations from sysfs for R5Fs, C66x DSPs, C71x DSPs 4. Tested device removal paths by executing 'modprobe -r ti_k3_dsp_remoteproc' and 'modprobe -r ti_k3_r5_remoteproc'. 5. Tested usecases where firmware not available at device probe time, but later in sysfs, able to load firmware into a remotecore and start it. [R5Fs] 6. Tested that each patch in this series generates no new warnings/errors. v9: Changelog: 1. Added R5 cleanup & refactoring along with existing DSP, M4 refactoring into this series. [Andrew] 2. Dropped Mailbox level IPC checks across R5, DSP, M4 drivers in IPC-only mode. [Andrew] Link to v8: https://lore.kernel.org/all/20250103101231.1508151-1-b-pa...@ti.com/ v8: Changelog: 1. Broken down refactoring into patches, each patch dealing with one function for ease in review.
