clocksource/drivers/sun5i: Add D1 hstimer support

2026-05-06T11:05:59+00:00

D1 high speed timer differs from existing timer-sun5i by register base offset. Add sunxi quirks to handle D1 specific offset. Add D1 compatible string to OF match table.

clocksource/drivers/sun5i: Handle error returns from devm_reset_control_get_optional_exclusive()

2026-03-24T17:30:44+00:00

The devm_reset_control_get_optional_exclusive() function may return an ERR_PTR in case of genuine reset control acquisition errors, not just NULL which indicates the legitimate absence of an optional reset. Add an IS_ERR() check after the call in sun5i_timer_probe(). On error, return the error code to ensure proper failure handling rather than proceeding with invalid pointers.

clocksource/drivers/sun5i: Add module owner

2025-09-23T08:51:44+00:00

The conversion to modules requires a correct handling of the module refcount in order to prevent to unload it if it is in use. That is especially true with the clockevents where there is no function to unregister them. The core time framework correctly handles the module refcount with the different clocksource and clockevents if the module owner is set. Add the module owner to make sure the core framework will prevent stupid things happening when the driver will be converted into a module.

Get rid of 'remove_new' relic from platform driver struct

2024-12-01T23:12:43+00:00

The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds

clocksource/drivers/sun5i: Remove surplus dev_err() when using platform_get_irq()

2023-10-11T10:06:41+00:00

There is no need to call the dev_err() function directly to print a custom message when handling an error from either the platform_get_irq() or platform_get_irq_byname() functions as both are going to display an appropriate error message in case of a failure. ./drivers/clocksource/timer-sun5i.c:260:2-9: line 260 is redundant because platform_get_irq() already prints an error Signed-off-by: Yang Li Acked-by: Jernej Skrabec Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/20230831041414.66434-1-yang.lee@linux.alibaba.com

clocksource/drivers/sun5i: Convert to platform device driver

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.

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.
