Subject: [PATCH 03/18] pwm: adp5585: don't control OSC_EN in the pwm driver
Date: Thu, 13 Mar 2025 14:19:20 +0000 [thread overview]
Message-ID: <20250313-dev-adp5589-fw-v1-3-20e80d4bd4ea@analog.com> (raw)
In-Reply-To: <20250313-dev-adp5589-fw-v1-0-20e80d4bd4ea@analog.com>
From: Nuno Sá <nuno.sa@analog.com>
The adp5585 is a Multi Function Device that can also be a gpio
controller and as it turns out, when OSC_EN is not set, we can't
reliably read the gpio value when it's configured as input. Hence,
OSC_EN will be set during probe by the parent device (and cleared on
unbind).
Moreover, we'll add support for the keymap matrix (input device) which
definitely needs OSC_EN to be set and so, we cannot afford that disabling
the PWM output also breaks the keymap events generation.
