Subject: [PATCH v5 0/2] Add support for SYSCON reset

Some SoCs contain reset controls for modules that are memory-mapped to
areas shared with other module configuration settings. This requires
synchronization across all drivers accessing this memory area. This
series adds a generic SYSCON reset driver to allow resets toggled
by bits in memory-mapped registers through SYSCON.

Changes from v4:
 - Added two more cells to DT ti,reset-bits property
 - Re-organized ti,reset-bits flag property defines
 - Moved TI_SYSCON_RESET in Kconfig
 - Other small fixes based on comments on v4

Changes from v3:
 - Add depends on HAS_IOMEM to Kconfig
 - Re-worked naming to be more TI specific for now
 - Changed DT binding to Philipp's suggestion

Changes from v2:
 - Rebased on v4.7-rc1
 - Removed the need to give reset specifier nodes an index address

Changes from v1:
 - Reset control information is now described in the reset node, this
   keeps the reset information centralized for easy verification
 - Other small fixups
