Subject: [PATCH 2/7] spi: zynqmp-gqspi: Pass speed/mode directly to config_op
Date: Thu, 16 Jan 2025 18:21:12 -0500	[thread overview]
Message-ID: <20250116232118.2694169-3-sean.anderson@linux.dev> (raw)
In-Reply-To: <20250116232118.2694169-1-sean.anderson@linux.dev>

In preparation for supporting transfer_one, which supplies the speed
from the spi_transfer instead of the spi_device, convert config_op to
take the speed and mode directly.
