To simulate bus overflow recovery in camera, cpas needs sysfs to take input from shell and vote the final value as given, instead of consolidated values from cpas clients. Add initial support for sysfs to add nodes for all drivers. Add sysfs based debug node to maintain and update all settings. Add cpas settings to override final bw voted to camnoc and mnoc ports. Usage: adb shell "echo <driver_name>#<setting_name>=<value> > /sys/devices/platform/soc/soc:qcom,cam-req-mgr/debug_node" Example:i adb shell "echo cpas#camnoc_bw=100 > /sys/devices/platform/soc/soc:qcom,cam-req-mgr/debug_node" Input format for updating settings is strict.
