Subject: [PATCH V2 4/8] spi: spi_amd: Updates to set tx/rx count functions
Date: Wed, 25 Sep 2024 19:06:40 +0530 [thread overview]
Message-ID: <20240925133644.2922359-5-Raju.Rangoju@amd.com> (raw)
In-Reply-To: <20240925133644.2922359-1-Raju.Rangoju@amd.com>
AMD SPI TX and RX counter registers are 1-byte length registers. The
existing value will be overwritten during register write, so masking is not
required.
