Subject: [PATCH v3 04/22] pwm: adp5585: don't control OSC_EN in the pwm driver
Date: Mon, 12 May 2025 13:38:56 +0100	[thread overview]
Message-ID: <20250512-dev-adp5589-fw-v3-4-092b14b79a88@analog.com> (raw)
In-Reply-To: <20250512-dev-adp5589-fw-v3-0-092b14b79a88@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.
