spi: aspeed: Improve handling of shared SPI
Merge series from Chin-Ting Kuo <chin-ting_kuo@aspeedtech.com>:
This patch series improves handling of SPI controllers that are
shared by spi-mem devices and other SPI peripherals.
The primary goal of this series is to support non-spi-mem devices in
the ASPEED FMC/SPI controller driver. It also addresses an issue in
the spi-mem framework observed when different types of SPI devices
operate concurrently on the same controller, ensuring that spi-mem
operations are properly serialized.
