Merge patch series "arm: aspeed: add initial AST2700 SoC support"

2026-06-29T21:29:56Z

Ryan Chen says: AST2700 is the 8th generation of Integrated Remote Management Processor introduced by ASPEED Technology Inc. It is a Board Management Controller (BMC) SoC family with a dual-die architecture: SoC0 ("CPU" die with four ARM Cortex-A35 application cores) and SoC1 ("IO" die with peripherals) each SoC have its own SCU PLLs, clock dividers and reset domains.

spi: aspeed: add AST2700 support

2026-06-29T19:43:20Z

AST2700 is a 64-bit SoC whose flash AHB windows are decoded above the 32-bit address space, so rework AHB addresses to uintptr_t and decoded window sizes to size_t. Signed-off-by: Ryan Chen

spi: cadence: Use reset_reset_bulk() for proper reset cycling

2026-06-08T08:50:06Z

Use the new reset_reset_bulk() API to properly cycle reset signals during probe instead of just deasserting them. This ensures the controller is properly reset before initialization.

spi: fsl_espi: fix read transactions

2026-05-15T11:28:30Z

Since commit 7917c2e35604 ("spi: fsl_espi: fix din offset") MTD is basically broken because any read transaction will get wrong data. While the commit in question will fix simple transfers (where both SPI_XFER_BEGIN and SPI_XFER_END is set), it will break the most common case, where opcode and address is send first and then data comes as a second transfer. This basically reverts commit 7917c2e35604 ("spi: fsl_espi: fix din offset") and make the fix particular for this simple case. Instead of providing two buffers for reading and writing, just malloc one which is used for both. This will work because the data is first written on the SPI bus and then it will be read (and overwite the written data) into the same buffer.

spi: apple: Add "apple,t8103-spi" compatible

2026-05-12T18:08:01Z

After discussion with the devicetree maintainers we agreed to not extend lists with the generic compatible "apple,spi" anymore [1]. Use "apple,t8103-spi" as base compatible as it is the SoC driver and bindings were originally written for. The t602x (M2 Pro/Max/Ultra) devicetrees submitted in [2] use this compatible as fallback instead of "apple,spi".

spi: sunxi: wait for TX/RX fifo reset done

2026-04-30T21:31:03Z

Once reset SPI TX or RX fifo, the underlying hardware need to take some time to actually settle down, the two bits will automatically clear to 0, so use a poll mechanism to check status bits to make sure it's done correctly. On Cubie A7A board which using A733 SoC, we encoutered a SPI nor flash timeout issue, it turns out that the SPI fifo reset take a few time to settle down, Add a loop to poll the status. This was the error message shows on A7A board once this issue happened. => sf probe ERROR: sun4i_spi: Timeout transferring data Failed to initialize SPI flash at 0:0 (error -2) Signed-off-by: Yixun Lan Reviewed-by: Jernej Skrabec Acked-by: Andre Przywara
