Subject: [PATCH v2 0/2] Add support for power budget
Date: Wed, 15 Jan 2025 15:41:56 +0100 [thread overview]
Message-ID: <20250115-feature_regulator_pw_budget-v2-0-0a44b949e6bc@bootlin.com> (raw)
In preparation for future support of PSE budget evaluation strategy and
power management, we need the power budget value of the power supply.
This addition allows the regulator to track the available power
budget, which will be essential for prioritizing ports when
making power allocation decisions.
The related budget evaluation strategy patch series sent:

Changes in v2:
- Add event notifier in case of power request over budget.
- Track how much budget is used instead of free power budget.
- Link to v1: https://lore.kernel.org/r/20250113-feature_regulator_pw_budget-v1-0-01e1d95c2015@bootlin.com
