Subject: [PATCH 05/12] dma-direct: add depdenencies to CONFIG_DMA_GLOBAL_POOL
Date: Mon, 16 Oct 2023 07:47:47 +0200	[thread overview]
Message-ID: <20231016054755.915155-6-hch@lst.de> (raw)
In-Reply-To: <20231016054755.915155-1-hch@lst.de>

CONFIG_DMA_GLOBAL_POOL can't be combined with other DMA coherent
allocators.  Add dependencies to Kconfig to document this, and make
kconfig complain about unment dependencies if someone tries.
