2022-07-01firmware: Hold a reference for of_find_compatible_node()Liang He
In of_register_trusted_foundations(), we need to hold the reference returned by of_find_compatible_node() and then use it to call of_node_put() for refcount balance.

2020-05-06firmware: tf: Different way of L2 cache enabling after LP2 suspendDmitry Osipenko
ASUS TF300T device may not work properly if firmware is asked to fully re-initialize L2 cache after resume from LP2 suspend. The downstream kernel of TF300T uses different opcode to enable cache after resuming from LP2, this opcode also works fine on Nexus 7 and Ouya devices. Supposedly, this may be needed by an older firmware versions.
