   4 Subject: leds: rgb: leds-ktd202x: I2C ID tables for KTD2026 and 2027
   5
   6 Add an i2c_device_id id_table to match manually instantiated
   7 (non device-tree / ACPI instantiated) KTD202x controllers as
   8 found on some x86 boards.
   9
  10 This table shows the maximum support LED channel for KTD2026
  11 (three LEDs) and KTD-2027 (4 LEDs).
