Merge tag 'renesas-cleanup-for-v4.3' of... 

Merge tag 'renesas-cleanup-for-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/cleanup

Merge "Renesas ARM Based SoC Cleanup for v4.3" from Simon Horman:

* Remove non-multiplatform code from timer
* Remove CONFIG_ARCH_SHMOBILE_MULTI check in setup-rcar-gen2.c
  as it is always true
* Remove legacy (non-multiplatform) support for both sh73a0/kzm9g and
  r8a7740/armadillo800eva
* Move to_rmobile_pd from header to source file where it is used
* Use BIT() macro instead of open coding in r-mobile PM code
* r8a7779: Remove usage of GENPD_FLAG_PM_CLK flag which has no effect

* tag 'renesas-cleanup-for-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  ARM: shmobile: timer: r8a73a4 and r8a7790 are multi-platform only
  ARM: shmobile: R-Car Gen2: CONFIG_ARCH_SHMOBILE_MULTI is always set
  ARM: shmobile: Remove obsolete zboot support
  ARM: shmobile: R-Mobile: Remove legacy PM Domain code
  ARM: shmobile: Remove unused dma-register.h
  ARM: shmobile: Remove legacy SoC code for R-Mobile A1
  ARM: shmobile: Drop r8a7740-armadillo800eva.dtb for legacy builds
  ARM: shmobile: Remove legacy armadillo800eva_defconfig
  ARM: shmobile: Remove legacy board code for Armadillo-800 EVA
  ARM: shmobile: Remove legacy SoC code for SH-Mobile AG5
  ARM: shmobile: Drop sh73a0-kzm9g.dtb for legacy builds
  ARM: shmobile: Remove legacy kzm9g_defconfig
  ARM: shmobile: Remove legacy board code for KZM-A9-GT
  ARM: shmobile: r8a7779: Remove GENPD_FLAG_PM_CLK flag
  ARM: shmobile: R-Mobile: Use BIT() macro instead of open coding
  ARM: shmobile: R-Mobile: Move to_rmobile_pd from header to source file
