Subject: [PATCH v1 1/2] dt-bindings: pinctrl: mt8192: Add drive-strength-microamp
Date: Wed, 25 May 2022 11:57:13 -0400	[thread overview]
Message-ID: <20220525155714.1837360-2-nfraprado@collabora.com> (raw)
In-Reply-To: <20220525155714.1837360-1-nfraprado@collabora.com>

Commit e5fabbe43f3f ("pinctrl: mediatek: paris: Support generic
PIN_CONFIG_DRIVE_STRENGTH_UA") added support for using
drive-strength-microamp instead of mediatek,drive-strength-adv.

Since there aren't any users of mediatek,drive-strength-adv on mt8192
yet, remove this property and add drive-strength-microamp in its place,
which has a clearer meaning.

Fixes: 4ac68333ff6d ("dt-bindings: pinctrl: mt8192: Add mediatek,drive-strength-adv property")

-              Describe the specific driving setup property.
-              For I2C pins, the existing generic driving setup can only support
-              2/4/6/8/10/12/14/16mA driving. But in specific driving setup, they
-              can support 0.125/0.25/0.5/1mA adjustment. If we enable specific
-              driving setup, the existing generic setup will be disabled.
-              The specific driving setup is controlled by E1E0EN.
-              When E1=0/E0=0, the strength is 0.125mA.
-              When E1=0/E0=1, the strength is 0.25mA.
-              When E1=1/E0=0, the strength is 0.5mA.
-              When E1=1/E0=1, the strength is 1mA.
-              EN is used to enable or disable the specific driving setup.
-              Valid arguments are described as below:
-              0: (E1, E0, EN) = (0, 0, 0)
-              1: (E1, E0, EN) = (0, 0, 1)
-              2: (E1, E0, EN) = (0, 1, 0)
-              3: (E1, E0, EN) = (0, 1, 1)
-              4: (E1, E0, EN) = (1, 0, 0)
-              5: (E1, E0, EN) = (1, 0, 1)
-              6: (E1, E0, EN) = (1, 1, 0)
-              7: (E1, E0, EN) = (1, 1, 1)
-              So the valid arguments are from 0 to 7.
