Subject: [PATCH 4/9] spi: spi_amd: Updates to set tx/rx count functions
Date: Wed, 18 Sep 2024 16:20:32 +0530	[thread overview]
Message-ID: <20240918105037.406003-5-Raju.Rangoju@amd.com> (raw)
In-Reply-To: <20240918105037.406003-1-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.
