2023-06-19clocksource/drivers/ingenic-timer: Use pm_sleep_ptr() macroPaul Cercueil1-6/+4
The use of the pm_sleep_ptr() macro allows the compiler to always see the dev_pm_ops structure and related functions, while still allowing the unused code to be removed, without the need for the __maybe_unused markings.

2023-04-13clocksource: ingenic: Add explicit include for cpuhotplug.hRob Herring1-2/+1
Removing include of cpu.h from of_device.h (included by of_platform.h) causes an error in ingenic-timer: drivers/clocksource/ingenic-timer.c: In function ‘ingenic_tcu_init’: drivers/clocksource/ingenic-timer.c:338:15: error: implicit declaration of function ‘cpuhp_setup_state’ The of_platform.h header is not necessary either, so it and of_address.h can be dropped.

2021-04-08clocksource/drivers/ingenic: Add support for the JZ4760Paul Cercueil1-0/+2
Add support for the TCU (Timer/Counter Unit) of the JZ4760 and JZ4760B SoCs. Signed-off-by: Paul Cercueil <paul@crapouillou.net> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20210308212302.10288-2-paul@crapouillou.net
2020-12-03clocksource/drivers/ingenic: Fix section mismatchDaniel Lezcano1-1/+1
The function ingenic_tcu_get_clock() is annotated for the __init section but it is actually called from the online cpu callback. That will lead to a crash if a CPU is hotplugged after boot time. Remove the __init annotation for the ingenic_tcu_get_clock() function.

2020-07-23clocksource/drivers/ingenic: Add high resolution timer support for SMP/SMT.周琰杰 (Zhou Yanjie)1-58/+124
Enable clock event handling on per CPU core basis. Make sure that interrupts raised on the first core execute event handlers on the correct CPU core. This driver is required by Ingenic processors that support SMP/SMT, such as JZ4780 and X2000. Tested-by: H.

2020-02-27clocksource/drivers/ingenic: Add support for TCU of X1000周琰杰 (Zhou Yanjie)1-1/+2
X1000 has a different TCU containing OST, since X1000, OST has been independent of TCU. This patch is prepare for later OST driver.

2019-08-08clocksource: Add a new timer-ingenic driverPaul Cercueil1-0/+356
This driver handles the TCU (Timer Counter Unit) present on the Ingenic JZ47xx SoCs, and provides the kernel with a system timer, a clocksource and a sched_clock.
