Subject: [PATCH net-next v6 0/7] net: pse-pd: Add new PSE c33 features
From: Kory Maincent (Dent Project) <kory.maincent@...tlin.com>
This patch series adds new c33 features to the PSE API.
- Expand the PSE PI informations status with power, class and failure
reason
- Add the possibility to get and set the PSE PIs power limit
Changes in v6:
- Rebase on top of net-next
- Link to v5: https://lore.kernel.org/r/20240628-feature_poe_power_cap-v5-0-5e1375d3817a@bootlin.com
Changes in v5:
- Fix few nitpick.
- Link to v4: https://lore.kernel.org/r/20240625-feature_poe_power_cap-v4-0-b0813aad57d5@bootlin.com
Changes in v4:
- Made few update in PSE extended state an substate.
- Add support for c33 pse power limit ranges.
- Few changes in the specs and the documentation.
- Link to v3: https://lore.kernel.org/r/20240614-feature_poe_power_cap-v3-0-a26784e78311@bootlin.com
Changes in v3:
- Use u32 instead of u8 size for c33 pse extended state and substate.
- Reformat the state and substate enumeration to follow Oleksij proposal which
is more IEEE 802.3 standard compliant
- Sent the first patch standalone in net.
- Link to v2: https://lore.kernel.org/r/20240607-feature_poe_power_cap-v2-0-c03c2deb83ab@bootlin.com
Changes in v2:
- Use uA and uV instead of mA and mV to have more precision in the power
calculation. Need to use 64bit variables for the calculation.
- Modify the pd-92x0behavior in case of setting the current out of the
available ranges. Report an error now.
- Link to v1: https://lore.kernel.org/r/20240529-feature_poe_power_cap-v1-0-0c4b1d5953b8@bootlin.com
