commit f5ac95f9ca2f439179a5baf48e1c0f22f83d936e upstream. TCSes have previously programmed data when rpmh_flush() is called. This can cause old data to trigger along with newly flushed. Fix this by cleaning SLEEP and WAKE TCSes before new data is flushed. With this there is no need to invoke rpmh_rsc_invalidate() call from rpmh_invalidate(). Simplify rpmh_invalidate() by moving invalidate_batch() inside.

commit bb7000677a1b287206c8d4327c62442fa3050a8f upstream. Currently rpmh ctrlr dirty flag is set for all cases regardless of data is really changed or not. Add changes to update dirty flag when data is changed to newer values. Update dirty flag everytime when data in batch cache is updated since rpmh_flush() may get invoked from any CPU instead of only last CPU going to low power mode. Also move dirty flag updates to happen from within cache_lock and remove unnecessary INIT_LIST_HEAD() call and a default case from switch.

[ Upstream commit 03729cfa0d543bc996bf959e762ec999afc8f3d2 ] Any user of wkup_m3_ipc calls wkup_m3_ipc_get to get a handle and this checks the value of the static variable m3_ipc_state to see if the wkup_m3 is ready. Currently this is populated during probe before rproc_boot has been called, meaning there is a window of time that wkup_m3_ipc_get can return a valid handle but the wkup_m3 itself is not ready, leading to invalid IPC calls to the wkup_m3 and system instability. To avoid this, move the population of the m3_ipc_state variable until after rproc_boot has succeeded to guarantee a valid and usable handle is always returned.

commit 4194b583c104922c6141d6610bfbce26847959df upstream. If the DTB for a device with an RZ/A2 SoC lacks a device node for the BSID register, the ID validation code falls back to using a register at address 0x0, which leads to undefined behavior (e.g. reading back a random value). This could be fixed by letting fam_rza2.reg point to the actual BSID register. However, the hardcoded fallbacks were meant for backwards compatibility with old DTBs only, not for new SoCs. Hence fix this by validating renesas_family.reg before using it.

commit c9e753767a9c75d2044fb7343950a6a992d34a16 upstream. Interrupts that don't have an associated wake event or GPIO wake events end up with an associate IRQ chip that is NULL and which causes IRQ code to crash. This is because we don't implicitly set the parent IRQ chip by allocating the interrupt at the parent. However, there really isn't a corresponding interrupt at the parent, so we need to work around this by setting the special no_irq_chip as the IRQ chip for these interrupts.
