Input: sun4i-ts - convert to platform remove callback returning void

2023-09-24T02:28:16Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Input: sun4i-ts - drop of_match_ptr for ID table

2023-03-17T11:17:36Z

The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here).

thermal/core: Use the thermal zone 'devdata' accessor in remaining drivers

2023-03-03T19:45:02Z

The thermal zone device structure is exposed to the different drivers and obviously they access the internals while that should be restricted to the core thermal code. In order to self-encapsulate the thermal core code, we need to prevent the drivers accessing directly the thermal zone structure and provide accessor functions to deal with. Use the devdata accessor introduced in the previous patch. No functional changes intended.

Input: sun4i-ts - switch to new of thermal API

2022-08-17T12:09:39Z

The thermal OF code has a new API allowing to migrate the OF initialization to a simpler approach. The ops are no longer device tree specific and are the generic ones provided by the core code. Convert the ops to the thermal_zone_device_ops format and use the new API to register the thermal zone with these generic ops.

Input: sun4i-ts - use devm_platform_ioremap_resource()

2019-07-24T09:49:13Z

devm_platform_ioremap_resource() internally have platform_get_resource() and devm_ioremap_resource() in it. So instead of calling them separately use devm_platform_ioremap_resource() directly. Signed-off-by: Mukesh Ojha Signed-off-by: Dmitry Torokhov

docs: arm: convert docs to ReST and rename to *.rst

2019-07-15T12:20:24Z

Converts ARM the text files to ReST, preparing them to be an architecture book. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
