Subject: [PATCH v9 2/7] leds: rgb: leds-ktd202x: I2C ID tables for KTD2026 and 2027
Date: Sat, 4 May 2024 18:41:00 +0200 [thread overview]
Message-ID: <20240504164105.114017-3-hdegoede@redhat.com> (raw)
In-Reply-To: <20240504164105.114017-1-hdegoede@redhat.com>
From: Kate Hsuan <hpa@redhat.com>
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).
