rtc: introduce features bitfield

2021-01-16T22:19:26Z

Introduce a bitfield to allow the drivers to announce the available features for an RTC. The main use case would be to better handle alarms, that could be present or not or have a minute resolution or may need a correct week day to be set. Use the newly introduced RTC_FEATURE_ALARM bit to then test whether alarms are available instead of relying on the presence of ops->set_alarm.

rtc: make definitions in include/uapi/linux/rtc.h actually useful for user space

2020-03-26T20:38:40Z

BIT() macro is not defined in UAPI headers; there is, however, similarly defined _BITUL() macro present in include/uapi/linux/const.h; use it instead and include and in order to make the definitions provided in the header useful.

rtc: define RTC_VL_READ values

2019-12-18T09:37:18Z

Currently, the meaning of the value returned by RTC_VL_READ is undocumented and left to the driver implementation. In order to get more meaningful values, define a set of values to use as to make clear to userspace what is the status of the various voltages feeding the RTC.

License cleanup: add SPDX license identifier to uapi header files with no license

2017-11-02T10:19:54Z

Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". otherwise syscall usage would not be possible. Update the files which contain no license information with an SPDX license identifier. The chosen identifier is 'GPL-2.0 WITH Linux-syscall-note' which is the officially assigned identifier for the Linux syscall exception. SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.
