This patchset is a follow-up work, which was originated with patch [1]. During the review of originally proposed solution, it has been discovered that a certain level of clean-up and re-factoring would be needed for CAAM Driver to remove static variables in JR probing functions, and some bits of CAAM driver code that is used for debug output purposes only. New solution is proposed in this series, and provides following enhancements to the CAAM Driver infrastructure: - CAAM Driver uses new bitmap to indicate capabilities, which has been previously accomplished by various assorted variables in caam_ctrl_priv structure - JR node parsing is made independent from the order of appearance in the DTB, indexing is now based on the address provided by the "reg" property - CAAM Driver checks the presence on JR nodes in DTB, and matches the access to JR HW units in its internal registers. If the JR HW unit is marked to be used by TrustZone - it would be marked appropriate and further probing of JR device would be stopped at the very early stage. Changelog with respect to original patch [1] is recorded in the updated version of the patch, which is included in this series.
