Hi Tony, Paul,

This patch series adds the minimal mailbox DT nodes for the SoCs that are
currently missing them (OMAP4, AM335x, DRA7). It also limits the legacy
mailbox platform device creation only for non-DT boot, and cleans up the
legacy hwmod addresses and attributes used for creating the sub-mailbox
devices. The sub-mailboxes in DT boot are not created until the OMAP
mailbox DT adoption series, and is not an issue since some of the other
required hwmod data for using legacy-mode devices have already been
cleaned up.

The patches are based on 3.16-rc2. The series do not have any order
dependencies with the OMAP mailbox cleanup series [1], and can be applied
in any order. The following shows the boot logs on various OMAP platforms
with just these patches on top of 3.16-rc2:
  OMAP2 (SDP2430)           : http://slexy.org/view/s21gGdJxXP
  OMAP3 (BeagleXM)          : http://slexy.org/view/s2n8Pc83Rp
  OMAP4 (PandaBoard)        : http://slexy.org/view/s21StNWKPz
  OMAP5 (OMAP5 uEVM)        : http://slexy.org/view/s2y3t6HZtk
  DRA7  (DRA7 EVM)          : http://slexy.org/view/s2qY23Mt97
  AM33xx (BeagleBone Black) : http://slexy.org/view/s2ce8jj35O
  AM43xx (AM437x GP EVM)    : http://slexy.org/view/s2nttmOLSq

This gave these build errors:

arch/arm/mach-davinci/pm.c: In function 'davinci_pm_probe':
arch/arm/mach-davinci/pm.c:127: error: lvalue required in asm statement
arch/arm/mach-davinci/pm.c:127: error: invalid lvalue in asm output 0
make[1]: *** [arch/arm/mach-davinci/pm.o] Error 1

Replacing davinci_cpu_suspend with &davinci_cpu_suspend fixed the issue.

With that change done, tested suspend-to-RAM on DA850 platform.
Also tested audio driver on DM365 platform with IRAM buffers enabled.

Can you also fold the following patch in? Without this the
kernel panics when suspend-to-RAM is enabled.
