clocksource/drivers/hyperv: add data structure for reference TSC MSR

2022-11-03T15:50:28Z

Add a data structure to represent the reference TSC MSR similar to other MSRs. This simplifies the code for updating the MSR. Signed-off-by: Anirudh Rayabharam Reviewed-by: Michael Kelley Link: https://lore.kernel.org/r/20221027095729.1676394-2-anrayabh@linux.microsoft.com Signed-off-by: Wei Liu

clocksource/drivers/arm_arch_timer: Fix CNTPCT_LO and CNTVCT_LO value

clocksource/drivers/imx-sysctr: handle nxp,no-divider property

2022-09-20T08:49:46Z

The previous hardware design embedds a internal divider for base clock. New design not has that divider, so check the nxp,no-divider property, if true, directly use base clock input, otherwise divide by 3 as before.

clocksource/drivers/timer-ti-dm: Get clock in probe with devm_clk_get()

2022-09-20T08:49:46Z

We can simplify the code a bit by getting the clock in probe, and using devm_clk_get(). This will also make further changes easier as the clock is available in probe instead of prepare.

clocksource/drivers/timer-ti-dm: Add flag to detect omap1

Let's make it clear that some features need to be tested currently on omap1. Only omap1 still uses platform_data. Signed-off-by: Tony Lindgren Reviewed-by: Janusz Krzysztofik Link: https://lore.kernel.org/r/20220815131250.34603-9-tony@atomide.com Signed-off-by: Daniel Lezcano

clocksource/drivers/timer-ti-dm: Move struct omap_dm_timer fields to driver

2022-09-20T08:49:46Z

There is no longer any need to expose the elements of struct omap_dm_timer outside the driver. The pwm and remoteproc drivers just use struct omap_dm_timer as a cookie. Let's move the elements of struct omap_dm_timer into struct dmtimer that is private to the driver. To do this, we mostly rename omap_dm_timer to dmtimer in the driver. We keep omap_dm_timer only for the exposed functions in the platform_data for the pwm and remoteproc drivers. Let's also add a note about not using the exposed functions internally as those will get deprecated eventually in favor of Linux generic frameworks.

clocksource/drivers/timer-ti-dm: Use runtime PM directly and check errors

2022-09-20T08:49:46Z

Use pm_runtime_resume_and_get() and check for a possible error returned. We want to do this as omap_dm_timer_enable() and omap_dm_timer_disable() are exposed to the pwm and remoteproc drivers, and in the following patch we turn struct omap_dm_timer into a cookie used by the exposed functions only.
