Subject: [PATCH 2/3] reset: simple: Support Loongson 2K0300 SoC
Date: Sat, 16 Aug 2025 03:33:27 +0000	[thread overview]
Message-ID: <20250816033327.11359-4-ziyao@disroot.org> (raw)
In-Reply-To: <20250816033327.11359-2-ziyao@disroot.org>

The controller has contiguous distinct control bits for each reset
signal, where setting to low represents reset assertion. Add support for
it through the reset-simple driver.
