Documentation: dt: reset: Add TI syscon reset binding
Add TI syscon reset controller binding. This will hook to the reset framework and use syscon/regmap to set reset bits. This allows reset control of individual SoC subsytems and devices with memory-mapped reset registers in a common register memory space. Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Suman Anna <s-anna@ti.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
