Subject: [PATCH v3 07/12] spi: s3c64xx: let the SPI core determine the bus number
Date: Fri, 16 Feb 2024 07:05:50 +0000	[thread overview]
Message-ID: <20240216070555.2483977-8-tudor.ambarus@linaro.org> (raw)
In-Reply-To: <20240216070555.2483977-1-tudor.ambarus@linaro.org>

Let the core determine the bus number, either by getting the alias ID
(as the driver forces now), or by allocating a dynamic bus number when
the alias is absent. Prepare the driver to allow dt aliases to be
absent.
