clocksource/drivers/sun5i: Convert to platform device driver

2023-08-18T10:15:22+00:00

Convert the sun5i hstimer driver to a platform device driver. This makes it work again on A20 and other systems where the clock is provided by a platform device driver.

clocksource/drivers/sun5i: Remove duplication of code and data

2023-08-18T10:15:06+00:00

Move the clocksource and clock_event_device structs into the main struct sun5i_timer, and update the code for the new layout. This removes a lot of duplication of both code and data.

clocksource/drivers/timer-sun5i: Convert to SPDX identifier

2022-05-18T09:08:59+00:00

The license information clearly states GPL version 2 only. The extra text which excludes warranties is an excerpt of the corresponding GPLv2 clause 11. So the SPDX identifier covers it completely.

clocksource/drivers/sun5i: Fail gracefully when clock rate is unavailable

2019-02-23T11:13:45+00:00

If the clock tree is not fully populated when the timer-sun5i init code is called, attempts to get the clock rate for the timer would fail and return 0. Make the init code for both clock events and clocksource check the returned clock rate and fail gracefully if the result is 0, instead of causing a divide by 0 exception later on.

clocksource/drivers: Rename CLOCKSOURCE_OF_DECLARE to TIMER_OF_DECLARE

2017-06-14T09:58:45+00:00

The CLOCKSOURCE_OF_DECLARE macro is used widely for the timers to declare the clocksource at early stage. However, this macro is also used to initialize the clockevent if any, or the clockevent only. It was originally suggested to declare another macro to initialize a clockevent, so in order to separate the two entities even they belong to the same IP. This was not accepted because of the impact on the DT where splitting a clocksource/clockevent definition does not make sense as it is a Linux concept not a hardware description. On the other side, the clocksource has not interrupt declared while the clockevent has, so it is easy from the driver to know if the description is for a clockevent or a clocksource, IOW it could be implemented at the driver level. So instead of dealing with a named clocksource macro, let's use a more generic one: TIMER_OF_DECLARE. The patch has not functional changes.
