Subject: [PATCH v2 0/2] riscv: spacemit: add pinctrl support for K3 SoC
Date: Wed, 23 Sep 2026 13:06:51 +0000 [thread overview]
Message-ID: <20260923-01-k3-pinctrl-support-v2-0-e76a917ee252@kernel.org> (raw)
The pinctrl controller of SpacemiT K3 SoC changed its register BIT
layout definition comparing to old K1 SoC, has different IO
power-domain tables, and extend drive strength bits to 4.
First patch fix drive strength configuration for external-voltage
IO pins.
Please note, this series is composed on top of K1 pinctrl patch which
sent to mailing list here [1]
