PM / devfreq: exynos: dev_pm_opp_put_*() accepts NULL argument

2020-12-09T05:51:12Z

The dev_pm_opp_put_*() APIs now accepts a NULL opp_table pointer and so there is no need for us to carry the extra check. Drop them. Acked-by: Chanwoo Choi Signed-off-by: Viresh Kumar

PM / devfreq: tegra30: Separate configurations per-SoC generation

2020-12-07T01:25:51Z

Previously we were using count-weight of the T124 for T30 in order to get EMC clock rate that was reasonable for T30. In fact the count-weight should be x2 times smaller on T30, but then devfreq was producing a bit too low EMC clock rate for ISO memory clients, like display controller for example. Now both Tegra ACTMON and Tegra DRM display drivers support interconnect framework and display driver tells to ICC what a minimum memory bandwidth is needed, preventing FIFO underflows. Thus, now we can use a proper count-weight value for Tegra30 and MC_ALL device config needs a bit more aggressive boosting. Add a separate ACTMON driver configuration that is specific to Tegra30.

PM / devfreq: tegra30: Support interconnect and OPPs from device-tree

2020-12-07T01:25:51Z

This patch moves ACTMON driver away from generating OPP table by itself, transitioning it to use the table which comes from device-tree. This change breaks compatibility with older device-trees and brings support for the interconnect framework to the driver. This is a mandatory change which needs to be done in order to implement interconnect-based memory DVFS, i.e. device-trees need to be updated. Now ACTMON issues a memory bandwidth requests using dev_pm_opp_set_bw() instead of driving EMC clock rate directly.

PM / devfreq: tegra20: Deprecate in a favor of emc-stat based driver

2020-11-23T07:01:13Z

Remove tegra20-devfreq in order to replace it with a EMC_STAT based devfreq driver. Previously we were going to use MC_STAT based tegra20-devfreq driver because EMC_STAT wasn't working properly, but now that problem is resolved. This resolves complications imposed by the removed driver since it was depending on both EMC and MC drivers simultaneously.

PM / devfreq: exynos-bus: Add registration of interconnect child device

2020-11-13T09:10:42Z

This patch adds registration of a child platform device for the exynos interconnect driver. It is assumed that the interconnect provider will only be needed when #interconnect-cells property is present in the bus DT node, hence the child device will be created only when such a property is present.

PM / devfreq: tegra30: Silence deferred probe error

2020-10-26T03:16:05Z

Tegra EMC driver was turned into a regular kernel driver, meaning that it could be compiled as a loadable kernel module now. Hence EMC clock isn't guaranteed to be available and clk_get("emc") may return -EPROBE_DEFER. Let's silence the deferred probe error.

PM / devfreq: tegra20: Relax Kconfig dependency

2020-10-26T03:15:43Z

The Tegra EMC driver now could be compiled as a loadable kernel module. Currently devfreq driver depends on the EMC/MC drivers in Kconfig, and thus, devfreq is forced to be a kernel module if EMC is compiled as a module. This build dependency could be relaxed since devfreq driver checks MC/EMC presence on probe, allowing kernel configuration where devfreq is a built-in driver and EMC driver is a loadable module. This change puts Tegra20 devfreq Kconfig entry on a par with the Tegra30 devfreq entry. Acked-by: Chanwoo Choi Signed-off-by: Dmitry Osipenko Signed-off-by: Chanwoo Choi

PM / devfreq: Remove redundant governor_name from struct devfreq

2020-10-26T02:50:51Z

The devfreq structure instance contains the governor_name and a governor instance. When need to show the governor name, better to use the name of devfreq_governor structure. So, governor_name variable in struct devfreq is a redundant and unneeded variable. Remove the redundant governor_name of struct devfreq and then use the name of devfreq_governor instance.
