Subject: [PATCH v2 2/2] mfd: cros_ec: Register keyboard backlight subdevice
Date: Sat, 11 May 2024 11:05:13 +0200 [thread overview]
Message-ID: <20240511-cros_ec-kbd-led-framework-v2-2-b20c48109e46@weissschuh.net> (raw)
In-Reply-To: <20240511-cros_ec-kbd-led-framework-v2-0-b20c48109e46@weissschuh.net>
Load cros_kbd_led_backlight when the EC reports EC_FEATURE_PWM_KEYB.
This makes cros_kbd_led_backlight work on machines without specific
ACPI or OF support for the keyboard backlight.
