platform/surface: aggregator_registry: omit battery & AC nodes on Surface Laptop 7

2026-06-01T15:54:49+00:00

[ Upstream commit 0488073a6c84571dd3cffe581a4a73a5fceb099d ] Surface Laptop 7 exposes battery and AC status via Qualcomm PMIC GLINK qcom_battmgr. Registering the standard SSAM battery and AC client devices on this platform causes duplicate power-supply devices to appear. Drop the SSAM battery and AC nodes from the Surface Laptop 7 registry group so that only the qcom_battmgr power supplies are instantiated.

Add SAM client device nodes for the Surface Pro 11 (Intel). Like with the Surface Pro 10 already, the node group is compatible, so it can be reused.

Get rid of 'remove_new' relic from platform driver struct

2024-12-01T23:12:43+00:00

The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds

platform/surface: Add OF support

2024-08-19T11:53:48+00:00

Add basic support for registering the aggregator module on Device Tree- based platforms. These include at least three generations of Qualcomm Snapdragon-based Surface devices: - SC8180X / SQ1 / SQ2: Pro X, - SC8280XP / SQ3: Devkit 2023, Pro 9 - X Elite: Laptop 7 / Pro11 Thankfully, the aggregators on these seem to be configured in an identical way, which allows for using these settings as defaults and no DT properties need to be introduced (until that changes, anyway). Based on the work done by Maximilian Luz, largely rewritten.
