Subject: [PATCH v5 08/15] drivers/spi: Use ARCH_DMA_MINALIGN instead of ARCH_KMALLOC_MINALIGN
Date: Wed, 24 May 2023 18:18:57 +0100	[thread overview]
Message-ID: <20230524171904.3967031-9-catalin.marinas@arm.com> (raw)
In-Reply-To: <20230524171904.3967031-1-catalin.marinas@arm.com>

ARCH_DMA_MINALIGN represents the minimum (static) alignment for safe DMA
operations while ARCH_KMALLOC_MINALIGN is the minimum kmalloc() objects
alignment.
