Subject: [PATCH 0/2] pinctrl: spacemit: add clock/reset support
Date: Sat, 12 Apr 2025 14:58:09 +0800	[thread overview]
Message-ID: <20250412-02-k1-pinctrl-clk-v1-0-e39734419a2d@gentoo.org> (raw)

SpacemiT K1 pinctrl requires two clocks in order to be functional,
also one reset line from hardware persepective.

In this series, adding clock property in dt-binding, and activate
them in the driver. But for reset, making it optional for now.

Notice that, devm_clk_get_optional_enabled() API has be choosed,
which will make old dtb blob still functioinal with new kernel.

For DT part patch, I plan to submit after clock driver merged.
This may result dtb warnings in this version due to the mising
clock property in pinctrl dt node.
