Subject: leds: rgb: leds-ktd202x: I2C ID tables for KTD2026 and 2027
|
||
|
|
|
||
|
|
Add an i2c_device_id id_table to match manually instantiated
|
||
|
|
(non device-tree / ACPI instantiated) KTD202x controllers as
|
||
|
|
found on some x86 boards.
|
||
|
|
|
||
|
|
This table shows the maximum support LED channel for KTD2026
|
||
|
|
(three LEDs) and KTD-2027 (4 LEDs).
