Subject: [PATCH v2 4/8] pinctrl: mvebu: pinctrl driver for 98DX2530 SoC
Date: Tue, 15 Mar 2022 10:31:39 +1300 [thread overview]
Message-ID: <20220314213143.2404162-5-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20220314213143.2404162-1-chris.packham@alliedtelesis.co.nz>
This pinctrl driver supports the 98DX25xx and 98DX35xx family of chips
from Marvell. It is based on the Marvell SDK with additions for various
(non-gpio) pin configurations based on the datasheet.
Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz>

Notes:
Changes in v2:
- Make pinctrl a child of a syscon node like the armada-7k-pinctrl
