mfd: Explicitly include correct DT includes

2023-08-18T20:48:03+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

drivers: remove struct module * setting from struct class

2023-03-17T14:16:27+00:00

There is no need to manually set the owner of a struct class, as the registering function does it automatically, so remove all of the explicit settings from various drivers that did so as it is unneeded. This allows us to remove this pointer entirely from this structure going forward. Cc: "Rafael J.

Revert "mfd: cros_ec: Add SCP Core-1 as a new CrOS EC MCU"

2023-01-09T20:32:52+00:00

This reverts commit 66ee379d743c69c726b61d078119a34d5be96a35. The feature flag introduced by Commit 66ee379d743c ("mfd: cros_ec: Add SCP Core-1 as a new CrOS EC MCU") was not first added in the source EC code base[1]. This can lead to the possible misinterpration of an EC's supported feature set, as well as causes issues with all future feature flag updates.

mfd: cros_ec: Add SCP Core-1 as a new CrOS EC MCU

MT8195 System Companion Processors(SCP) is a dual-core RISC-V MCU. Add a new CrOS feature ID to represent the SCP's 2nd core. The 1st core is referred to as 'core 0', and the 2nd core is referred to as 'core 1'.

platform/chrome: cros_ec_proto: Rename cros_ec_command function

2022-06-08T08:14:53+00:00

cros_ec_command() is the name of a function as well as a struct, as such it can confuse indexing tools (like ctags). Avoid this by renaming it to cros_ec_cmd(). Update all the callsites to use the new name. This patch is a find-and-replace, so should not introduce any functional changes.

Don't create a device for the peripheral charger (PCHG) if there aren't any peripheral charger ports. This removes a device on most ChromeOS systems, because the peripheral charger functionality isn't always present.

platform/chrome: cros_ec_proto: Use EC struct for features

2021-10-31T22:52:39+00:00

The Chrome EC's features are returned through an ec_response_get_features struct, but they are stored in an independent array. Although the two are effectively the same at present (2 unsigned 32 bit ints), there is the possibility that they could go out of sync. Avoid this by only using the EC struct to store the features.
