leds: Use named initializers for arrays of i2c_device_data

2026-06-17T10:29:48+00:00

While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct i2c_device_id that replaces .driver_data by an anonymous union. While touching all these arrays, unify usage of whitespace and commas. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

leds: leds-lp55xx: Convert mutex lock/unlock to guard API

2024-07-11T11:46:25+00:00

Convert any entry of mutex lock/unlock to guard API and simplify code. With the use of guard API, handling for selttest functions can be greatly simplified.

leds: leds-lp55xx: Generalize update_program_memory function

2024-06-26T16:08:30+00:00

LED Driver based on lp55xx all use the same logic to write memory in SMEM. The only difference is that legacy chip doesn't support pages and have the engine regs one after another. To handle this apply the same logic used for load_engine also for update_program_memory. Introduce a new config in device_config, base_prog. For LED chip that doesn't support pages, offset this values of 32 for each engine. Update all lp55xx based LED driver to use this new function and define all the required bits.
