2023-11-30pmdomain: imx-pgc: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Set GENPD_FLAG_ACTIVE_WAKEUP for all RPM power domains so that power domains necessary for wakeup/"awake path" devices are kept on across suspend. This is needed for example for the *_AO ("active-only") variants of the RPMPDs used by the CPU. Those should maintain their votes also across system suspend to ensure the CPU can keep running for the whole suspend process (ending in a firmware call). When the RPM firmware detects that the CPUs are in a deep idle state it will drop those votes automatically.

2023-10-26pmdomain: imx: Make imx pgc power domain also set the fwnodePengfei Li1-0/+1
Currently, The imx pgc power domain doesn't set the fwnode pointer, which results in supply regulator device can't get consumer imx pgc power domain device from fwnode when creating a link. This causes the driver core to instead try to create a link between the parent gpc device of imx pgc power domain device and supply regulator device. However, at this point, the gpc device has already been bound, and the link creation will fail. So adding the fwnode pointer to the imx pgc power domain device will fix this issue.

2023-10-24pmdomain: bcm: bcm2835-power: check if the ASB register is equal to enableMaíra Canal1-1/+1
The commit c494a447c14e ("soc: bcm: bcm2835-power: Refactor ASB control") refactored the ASB control by using a general function to handle both the enable and disable. But this patch introduced a subtle regression: we need to check if !!(readl(base + reg) & ASB_ACK) == enable, not just check if (readl(base + reg) & ASB_ACK) == true. Currently, this is causing an invalid register state in V3D when unloading and loading the driver, because `bcm2835_asb_disable()` will return -ETIMEDOUT and `bcm2835_asb_power_off()` will fail to disable the ASB slave for V3D.

2023-09-21pmdomain: arm: Add the SCMI performance domainUlf Hansson3-0/+154
To enable support for performance scaling (DVFS) for generic devices with the SCMI performance protocol, let's add an SCMI performance domain. This is being modelled as a genpd provider, with support for performance scaling through genpd's ->set_performance_state() callback. Note that, this adds the initial support that allows consumer drivers for attached devices, to vote for a new performance state via calling the dev_pm_genpd_set_performance_state(). However, this should be avoided as it's in most cases preferred to use the OPP library to vote for a new OPP instead. The support using the OPP library isn't part of this change, but needs to be implemented from subsequent changes.
