[PATCH v3 0/2] spi: aspeed: Improve handling of shared SPI controllers

[Chin-Ting Kuo]

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.

Changes in v2:
  - Separate transfer_one_message() function implementation into
    transfer_one() and prepare_message() in controller driver.

Changes in v3:
  - Add testing information for both patches.
  - Expand commit message descriptions for the non-spi-mem device
    support changes.

  spi: spi-mem: Protect dirmap_create() with spi_mem_access_start/end
  spi: aspeed: Add support for non-spi-mem devices
