Subject: [PATCH v2 11/15] spi: Get rid of old SPI_MASTER_NO_TX & SPI_MASTER_NO_RX
Date:   Mon, 10 Jul 2023 18:49:28 +0300
Message-Id: <20230710154932.68377-12-andriy.shevchenko@linux.intel.com>
In-Reply-To: <20230710154932.68377-1-andriy.shevchenko@linux.intel.com>
References: <20230710154932.68377-1-andriy.shevchenko@linux.intel.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Convert the users from SPI_MASTER_NO_TX and/or SPI_MASTER_NO_RX
to SPI_CONTROLLER_NO_TX and/or SPI_CONTROLLER_NO_RX respectively
and kill the not used anymore definitions.
