OPP: call of_node_put() on error path in _bandwidth_supported()

2022-06-09T08:30:34Z

[ Upstream commit 907ed123b9d096c73e9361f6cd4097f0691497f2 ] This code does not call of_node_put(opp_np) if of_get_next_available_child() returns NULL. But it should.

OPP: Add support of "opp-microwatt" for EM registration

2022-03-03T04:05:04Z

The Energy Model (EM) can be created based on DT entry: 'dynamic-power-coefficient'. It's a 'simple' EM which is limited to the dynamic power. It has to fit into the math formula which requires also information about voltage. Some of the platforms don't expose voltage information, thus it's not possible to use EM registration using DT. This patch aims to fix it. It introduces new implementation of the EM registration callback. The new mechanism relies on the new OPP feature allowing to get power (which is coming from "opp-microwatt" DT property) expressed in micro-Watts. The patch also opens new opportunity to better support platforms, which have a decent static power. It allows to register the EM based on real power measurements which models total power (static + dynamic), so better reflects real HW. Signed-off-by: Lukasz Luba Signed-off-by: Viresh Kumar

OPP: Add "opp-microwatt" supporting code

2022-03-03T04:05:04Z

Add new property to the OPP: power value. The OPP entry in the DT can have "opp-microwatt". Add the needed code to handle this new property in the existing infrastructure. Signed-off-by: Lukasz Luba Signed-off-by: Viresh Kumar

opp: Expose of-node's name in debugfs

2022-02-11T04:29:04Z

It is difficult to find which OPPs are active at the moment, specially if there are multiple OPPs with same frequency available in the device tree (controlled by supported hardware feature). Expose name of the DT node to find out the exact OPP. While at it, also expose level field. Reported-by: Leo Yan Tested-by: Leo Yan Signed-off-by: Viresh Kumar

opp: Fix return in _opp_add_static_v2()

2021-10-08T07:54:46Z

Fix sparse warning: drivers/opp/of.c:924 _opp_add_static_v2() warn: passing zero to 'ERR_PTR' For duplicate OPPs 'ret' be set to zero. Fixes: deac8703da5f ("PM / OPP: _of_add_opp_table_v2(): increment count only if OPP is added") Signed-off-by: YueHaibing Signed-off-by: Viresh Kumar

opp: Add more resource-managed variants of dev_pm_opp_of_add_table()

2021-10-04T11:03:15Z

Add resource-managed variants of dev_pm_opp_of_add_table_indexed() and dev_pm_opp_of_add_table_noclk(), allowing drivers to remove boilerplate code. Signed-off-by: Dmitry Osipenko [ Viresh: Added underscore to devm_of_add_table_indexed() ] Signed-off-by: Viresh Kumar

opp: Change type of dev_pm_opp_attach_genpd(names) argument

2021-10-04T09:08:59Z

Elements of the 'names' array are not changed by the code, constify them for consistency. Signed-off-by: Dmitry Osipenko Signed-off-by: Viresh Kumar

opp: Fix required-opps phandle array count check

2021-10-04T06:53:09Z

The 'required-opps' property is optional. So of_count_phandle_with_args() can return -ENOENT when queried for required-opps. Handle this case. Signed-off-by: Pavankumar Kondeti Signed-off-by: Viresh Kumar
