Subject: [PATCH v2 0/3] PWM framework: add support referencing PWMs from ACPI
Date: Wed, 12 Jun 2019 10:36:05 +0200 [thread overview]
Message-ID: <cover.1560327219.git.nikolaus.voss@loewensteinmedical.de> (raw)
As described in Documentation/firmware-guide/acpi/gpio-properties.rst a
GPIO can be referenced from ACPI ASL _DSD with the "gpios"-property of the
form:
Package () { "gpios", Package () { ref, index, pin, active_low }}
The second patch of this series adds support for specifing a PWM
reference in ASL of the form
Package () { "pwms", Package () { ref, index, pwm-period [, pwm flags]}}
The first patch of this series is necessary to resolve the "ref" in ASL
if the table has been loaded by efivar_ssdt_load() or configfs.
The third patch of this series makes leds-pwm use the ACPI-enabled
PWM framework.
v2:
- fixes by Pavel Machek and Dan Murphy
Nikolaus Voss (3):
ACPI: Resolve objects on host-directed table loads
PWM framework: add support referencing PWMs from ACPI
leds-pwm.c: support ACPI via firmware-node framework
