Hello all,

This is the reworked patch turned into a series to allow upstream kernels
to make use of OP-TEE on the OMAP2+ platform.

Thanks,
Andrew

Changes from v1:
 - Split into logical patches
 - Check for OP-TEE in DT only once
 - Check the OP-TEE node is "okay"

Changes from v2:
 - Add HS patch using 'optee_available'

Andrew F. Davis (4):
  ARM: OMAP2+: Add omap_secure_init callback hook for secure
    initialization
  ARM: OMAP2+: Introduce check for OP-TEE in omap_secure_init()
  ARM: OMAP2+: Use ARM SMC Calling Convention when OP-TEE is available
  ARM: OMAP2+: sleep43xx: Call secure suspend/resume handlers
