power: reset: at91-shdwc: add new shutdown controller driver

2016-04-10T15:17:38Z

Sama5d2 SoC has a completely new shutdown controller with new features and register layout. It thus makes sense to add a new driver for this new peripheral. This driver is Device Tree only and handles events from the wake-up pin and the RTC. As the register layout may change in the future, so some values are encoded in a configuration structure.

power: reset: Fix dependencies for !HAS_IOMEM archs

2016-02-15T05:06:07Z

Not every arch has io memory. So, unbreak the build by fixing the dependencies. Signed-off-by: Richard Weinberger Signed-off-by: Sebastian Reichel

power/reset: versatile: support the actual versatile

2016-02-15T04:45:22Z

While this driver is named after the Versatile family of boards (ARM reference designs) the machine actually called Versatile was not supported. This patch makes the driver handle also that machine. We augment the register names for the reset to *VERSATILE* as well since it is the same register offsets for Versatile and RealView.

power/reset: at91-reset: add missing of_node_put

2015-12-05T01:06:49Z

for_each_matching_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. A simplified version of the semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // @@ expression e,e1; local idexpression np; @@ for_each_matching_node(np, e1) { ... when != of_node_put(np) when != e = np ( return np; | + of_node_put(np); ? return ...; ) ... } // Signed-off-by: Julia Lawall Signed-off-by: Sebastian Reichel

power: reset: at91-reset/trivial: driver applies to SAMA5 family as well

2015-09-22T13:45:39Z

This diver doesn't applies only on SAM9 SoC families but on SAMA5 families as well. Signed-off-by: Nicolas Ferre Signed-off-by: Sebastian Reichel

power/reset: at91-poweroff: get and use slow clock

2015-09-22T13:18:53Z

Commit dca1a4b5ff6e ("clk: at91: keep slow clk enabled to prevent system hang") added a workaround for the slow clock as it is not properly handled by its users. Get and use the slow clock as it is necessary for the at91 shutdown controller. Signed-off-by: Alexandre Belloni Signed-off-by: Sebastian Reichel

power/reset: at91-poweroff: allow compiling as a module

2015-09-22T13:18:53Z

It was not possible to compile at91-poweroff as a module. Implement .remove() to allow it. Also switch to module_platform_driver_probe() as it is not hotpluggable. Signed-off-by: Alexandre Belloni Signed-off-by: Sebastian Reichel

power/reset: at91-reset: remove useless at91_reset_platform_probe()

2015-09-22T13:18:52Z

Since all the at91 platforms are now DT only, at91_reset_platform_probe() is now useless, remove it. Signed-off-by: Alexandre Belloni Signed-off-by: Sebastian Reichel
