Subject: [PATCH v5 0/2] Add support for SYSCON reset
Date: Mon, 27 Jun 2016 12:12:15 -0500 [thread overview]
Message-ID: <20160627171217.4715-1-afd@ti.com> (raw)
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
