treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 79

2019-05-24T15:37:51Z

Based on 1 normalized pattern(s): licensed under the gpl v2 or later extracted by the scancode license scanner the SPDX license identifier GPL-2.0-or-later has been chosen to replace the boilerplate/reference in 1 file(s).

treewide: Add SPDX license identifier - Makefile/Kconfig

Add SPDX license identifiers to all Make/Kconfig files which: - Have no license information of any form These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

platform/olpc: Make ec explicitly non-modular

2016-08-29T05:31:52Z

The Kconfig entry controlling compilation of this code is: arch/x86/Kconfig:config OLPC arch/x86/Kconfig: bool "One Laptop Per Child support" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

OLPC: Use %*ph specifier instead of passing direct values

2015-10-06T22:22:08Z

The %*ph specifier allows to dump small buffers in hex format. Let's use it instead of passing direct values via stack. Signed-off-by: Andy Shevchenko Acked-by: Paul Fox Signed-off-by: Darren Hart

drivers/platform/olpc/olpc-ec.c: initialise earlier

2013-08-23T16:51:22Z

Being a low-level component, various drivers (e.g. olpc-battery) assume that it is ok to communicate with the OLPC Embedded Controller during probe. Therefore the OLPC EC driver must be initialised before other drivers try to use it. This was the case until it was recently moved out of arch/x86 and restructured around commits ac2504151f5a ("Platform: OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86: OLPC: switch over to using new EC driver on x86"). Use arch_initcall so that olpc-ec is readied earlier, matching the previous behaviour. Fixes a regression introduced in Linux-3.6 where various drivers such as olpc-battery and olpc-xo1-sci failed to load due to an inability to communicate with the EC. The user-visible effect was a lack of battery monitoring, missing ebook/lid switch input devices, etc. Signed-off-by: Daniel Drake Cc: Andres Salomon Cc: Paul Fox Cc: Thomas Gleixner Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Platform: OLPC: move global variables into priv struct

2012-08-01T03:27:31Z

Populate olpc_ec_priv with variables that were previously global. This makes things a tad bit clearer, IMO. Signed-off-by: Andres Salomon Acked-by: Paul Fox Reviewed-by: Thomas Gleixner

Platform: OLPC: move debugfs support from x86 EC driver

2012-08-01T03:27:31Z

There's nothing about the debugfs interface for the EC driver that is architecture-specific, so move it into the arch-independent driver. The code is mostly unchanged with the exception of renamed variables, coding style changes, and API updates. Signed-off-by: Andres Salomon Acked-by: Paul Fox Reviewed-by: Thomas Gleixner

x86: OLPC: switch over to using new EC driver on x86

2012-08-01T03:27:30Z

This uses the new EC driver framework in drivers/platform/olpc. The XO-1 and XO-1.5-specific code is still in arch/x86, but the generic stuff (including a new workqueue; no more running EC commands with IRQs disabled!) can be shared with other architectures.

Platform: OLPC: add a suspended flag to the EC driver

2012-08-01T03:27:30Z

A problem we've noticed on XO-1.75 is when we suspend in the middle of an EC command. Don't allow that. In the process, create a private object for the generic EC driver to use; we have a framework for passing around a struct, use that rather than a proliferation of global variables.

Platform: OLPC: turn EC driver into a platform_driver

2012-08-01T03:27:30Z

The 1.75-based OLPC EC driver already does this; let's do it for all EC drivers. This gives us nice suspend/resume hooks, amongst other things. We want to run the EC's suspend hooks later than other drivers (which may be setting wakeup masks or be running EC commands). We also want to run the EC's resume hooks earlier than other drivers (which may want to run EC commands). Signed-off-by: Andres Salomon Acked-by: Paul Fox Reviewed-by: Thomas Gleixner
