Similar change was done by commit b4c2c151b14b ("Kconfig: Remove all default n/no options") and again sync is required. default n/no doesn't need to be specified. It is default option anyway.

spi: add support for Amlogic A1 SPI Flash Controller

2023-10-27T16:49:52Z

Add A1 SPIFC driver from Linux. Slightly modified to use u-boot driver framework and accommodate to lack of ioread32_rep/iowrite32_rep.

spi: mtk_spim: prevent global pll clock override

2023-10-11T17:21:33Z

With commit 793e62301180 ("spi: mtk_spim: get spi clk rate only once") a new system to calculate the SPI clocks has been added. Unfortunately, the do_div macro overrides the global priv->pll_clk_rate field. This will cause to have a reduced clock rate on each subsequent SPI call.

spi: nxp_fspi: reset the FLSHxCR1 registers

2023-10-10T02:13:51Z

Reset the FLSHxCR1 registers to default value. ROM may set the register value and it affects the SPI NAND normal functions. Signed-off-by: Han Xu Signed-off-by: Peng Fan

spi: zynqmp_qspi: Workaround for small data cache issue

2023-09-21T11:20:12Z

Cache related issues are seen with small sized data reads. Due to this, proper data is not read. Also some times sf probe fails randomly. To workaround this issue, invalidate dcache after read DMA is triggered.

spi: zynqmp_qspi: Change flush cache to invalidate cache

2023-09-21T11:20:12Z

Before DMA read, ideally cache should be invalidated, so that data from memory will be updated to cache after DMA is completed. But flush_dcache_range is being used which is incorrect. Change flush_dcache_range to invalidate_dcache_range.

spi: mtk_spim: clear IRQ enable bits

2023-08-03T13:40:49Z

In u-boot we don't use IRQ. Instead, we poll busy bit in SPI_STATUS. However these IRQ enable bits may be set in previous boot stage (BootROM). If we leave these bits not cleared, although u-boot has disabled IRQ and nothing will happen, the linux kernel may encounter panic during initializing the spim driver due to IRQ event happens before IRQ handler is properly setup. This patch clear IRQ bits to prevent this from happening. Signed-off-by: SkyLake.Huang Signed-off-by: Weijie Gao Reviewed-by: Jagan Teki
