From 07c411346cb2493e4f59a8affbd35f5efc2ec736 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Thu, 17 Mar 2022 23:52:34 -0500 Subject: [PATCH] i2c: sun6i_p2wi: Add support for DM clocks and resets Currently, clock/reset setup for this device is handled by a platform-specific function and is intermixed with non-DM pinctrl setup. Use the devicetree to get clocks/resets, which disentagles it from the pinctrl setup in preparation for moving to DM_PINCTRL.
