power: reset: at91-reset: remove leftover platform_device_id

2017-01-18T16:05:46+00:00

commit eacd8d09db7f ("power/reset: at91-reset: remove useless at91_reset_platform_probe()") removed non DT probe support but forgot to remove the now useless id_table. Do that now. Signed-off-by: Alexandre Belloni Signed-off-by: Sebastian Reichel

power: reset: at91-reset: add samx7 support

2017-01-18T16:05:38+00:00

Add samx7 support. It is lacking a few bits and needs a new reset function. Signed-off-by: Szemző András Signed-off-by: Alexandre Belloni Signed-off-by: Sebastian Reichel

power: reset: at91-reset: Fix module autoload

2016-10-19T03:16:09+00:00

If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/power/reset/at91-reset.ko | grep alias $ After this patch: $ modinfo drivers/power/reset/at91-reset.ko | grep alias alias: of:N*T*Catmel,sama5d3-rstcC* alias: of:N*T*Catmel,sama5d3-rstc alias: of:N*T*Catmel,at91sam9g45-rstcC* alias: of:N*T*Catmel,at91sam9g45-rstc alias: of:N*T*Catmel,at91sam9260-rstcC* alias: of:N*T*Catmel,at91sam9260-rstc alias: platform:at91-sam9g45-reset alias: platform:at91-sam9260-reset Signed-off-by: Javier Martinez Canillas Signed-off-by: Sebastian Reichel

power/reset: at91-reset: add missing of_node_put

2015-12-05T01:06:49+00:00

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

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-reset: get and use slow clock

2015-09-22T13:18:52+00:00

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 reset controller. Signed-off-by: Alexandre Belloni Signed-off-by: Sebastian Reichel

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

2015-09-22T13:18:52+00:00

It was not possible to compile at91-reset 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()

2015-09-22T13:18:52+00:00

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

power: reset: at91: add sama5d3 reset function

2015-07-20T16:12:09+00:00

This patch introduces a new compatible string: "atmel,sama5d3-rstc" and new reset function for sama5d3 and later chips. As in sama5d3 or later chips, we don't have to shutdown the DDR controller before reset. Shutdown the DDR controller before reset is a workaround to avoid DDR signal driving the bus, but since sama5d3 and later chips there is no such a conflict. So in this patch: 1. the sama5d3 reset function only need to write the rstc register and return. 2. we can remove the code related with sama5d3 DDR controller as we don't use it at all.

power: at91-reset: Constify platform_device_id

The platform_device_id is not modified by the driver and core uses it as const. Signed-off-by: Krzysztof Kozlowski Acked-by: Alexandre Belloni Signed-off-by: Sebastian Reichel
