clocksource/drivers/cadence-ttc: Fix some kernel-doc warnings

2023-12-27T14:37:11Z

Fix some function kernel-doc warnings to placate scripts/kernel-doc. timer-cadence-ttc.c:79: warning: Function parameter or member 'clk_rate_change_nb' not described in 'ttc_timer' timer-cadence-ttc.c:158: warning: Function parameter or member 'cs' not described in '__ttc_clocksource_read' timer-cadence-ttc.c:194: warning: expecting prototype for ttc_set_{shutdown|oneshot|periodic}().

clocksource: Explicitly include correct DT includes

2023-08-28T18:30:57Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

clocksource/drivers/cadence-ttc: Fix memory leak in ttc_timer_probe

2023-06-23T07:33:44Z

Smatch reports: drivers/clocksource/timer-cadence-ttc.c:529 ttc_timer_probe() warn: 'timer_baseaddr' from of_iomap() not released on lines: 498,508,516. timer_baseaddr may have the problem of not being released after use, I replaced it with the devm_of_iomap() function and added the clk_put() function to cleanup the "clk_ce" and "clk_cs".

clocksource/drivers/cadence_ttc: Fix memory leak in ttc_setup_clockevent()

2020-12-03T18:16:26Z

If clk_notifier_register() failed, ttc_setup_clockevent() will return without freeing 'ttcce', which will leak memory.

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

clocksource/drivers/cadence-ttc: Use ttc driver as platform driver

2020-01-16T18:06:57Z

Currently TTC driver is TIMER_OF_DECLARE type driver. Because of that, TTC driver may be initialized before other clock drivers. If TTC driver is dependent on that clock driver then initialization of TTC driver will failed. So use TTC driver as platform driver instead of using TIMER_OF_DECLARE.
