Subject: [PATCH 02/10] spi: rzv2m-csi: Adopt HZ_PER_MHZ for max spi clock
Date: Sat, 15 Jul 2023 02:03:59 +0100 [thread overview]
Message-ID: <20230715010407.1751715-3-fabrizio.castro.jz@renesas.com> (raw)
In-Reply-To: <20230715010407.1751715-1-fabrizio.castro.jz@renesas.com>
Make use of HZ_PER_MHZ for CSI_MAX_SPI_SCKO to make it clear
what its value means.
