The sleep/wake state batch requests are saved in a linked list and
flushed along with other sleep/wake request when entering system low
power modes. Caches are flushed only if the state flag is marked dirty.
A race situation could cause the batch sleep/wake requests to not be
flushed. Here is how this could happen -
- Interconnect driver (ICC) invalidates the sleep/wake requests
- RSC driver clears the TCSes (BCM, VRM, ARC sleep votes cleared)
- ICC sends an active state response-required request
- RSC driver sends the AMC request
- RPMH waits on the response, calls wait_for_completion
- Scheduler schedules idle thread
- cpuidle enters cluster idle state
- RPMH flushes cache and marks cache clean
(no BCM votes in TCS)
- RSC driver receives IRQ response
- RPMH calls complete()
- ICC worker thread resumes execution
- ICC driver calls RPMH driver with updated sleep and wake votes
- RPMH caches the request, *cache is NOT marked dirty*
- Scheduler schedules idle thread
- cpuidle enters cluster idle state
- Cache is clean and nothing to flush
- CPU enters idle
=>ICC sleep/wake votes are not sent
Fix this by dirtying the cache state even when caching batch requests.

Use Vmax from play effect in haptics_set_gain() only if the effect
is valid. Otherwise, use Vmax from the haptics configuration instead.

Debugfs support for loopback is obsolete. This is
not supported on current or future platforms.
Remove it from debugfs to prevent any security issues
as it allows to access DDR.

consolidate fragment contains the all the debug features
on top of qgki fragment for regular debugging and debug
fragment contains memory debug features. Add support for
fragement merging support in the both generate_defconfig.sh
and fragement_menuconfig.sh scripts.

Add initial consolidate defconfig fragment for the lahaina SoC.
Consolidate fragement contains all debug features needed on
top of lahaina_QGKI.config fragement and these flags should not
show significant performance impact. lahaina_debug.config fragment
contains memory debug features, which shows the performance
impact. This enables intenal testing to use the images based on
lahaina-qgki-consoldiate_defconfig defconfig instead of
lahaina-qgki_defconfig defconfig.
