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: Move inline functions to driver for am6

2022-07-27T15:00:48Z

The __omap_dm_timer_* inline functions in the header are no longer needed outside the driver, and the header ifdefs prevent the driver working for ARCH_K3. Let's move the inline functions to the driver and drop the ifdefs and drop the unused functions __omap_dm_timer_override_errata() and __omap_dm_timer_load_start().

pwm: Add support for Xilinx AXI Timer

2022-04-22T16:30:44Z

This adds PWM support for Xilinx LogiCORE IP AXI soft timers commonly found on Xilinx FPGAs. At the moment clock control is very basic: we just enable the clock during probe and pin the frequency. In the future, someone could add support for disabling the clock when not in use. Some common code has been specially demarcated. While currently only used by the PWM driver, it is anticipated that it may be split off in the future to be used by the timer driver as well. This driver was written with reference to Xilinx DS764 for v1.03.a [1].

clocksource/drivers/arm_arch_timer: Use event stream scaling when available

2022-03-07T17:27:22Z

With FEAT_ECV and the 1GHz counter, it is pretty likely that the event stream divider doesn't fit in the field that holds the divider value (we only have 4 bits to describe counter bits [15:0] Thankfully, FEAT_ECV also provides a scaling mechanism to switch the field to cover counter bits [23:8] instead. Enable this on arm64 when ECV is available (32bit doesn't have any detection infrastructure and is unlikely to be run on an ARMv8.6 system anyway).
