e3228ed9 - spi: spi-mem: Convert Aspeed SMC driver to spi-mem

Mon, 09 May 2022 17:56:08 +0000

spi: spi-mem: Convert Aspeed SMC driver to spi-memThis SPI driver adds support for the Aspeed static memory controllersof the AST2600, AST2500 and AST2400 SoCs using the spi-mem interface. * AST2600 Firmware SPI Memory Controller (FMC) . BMC firmware . 3 chip select pins (CE0 ~ CE2) . Only supports SPI type flash memory . different segment register interface . single, dual and quad mode. * AST2600 SPI Flash Controller (SPI1 and SPI2) . host firmware . 2 chip select pins (CE0 ~ CE1) . different segment register interface . single, dual and quad mode. * AST2500 Firmware SPI Memory Controller (FMC) . BMC firmware . 3 chip select pins (CE0 ~ CE2) . supports SPI type flash memory (CE0-CE1) . CE2 can be of NOR type flash but this is not supported by the driver . single, dual mode. * AST2500 SPI Flash Controller (SPI1 and SPI2) . host firmware . 2 chip select pins (CE0 ~ CE1) . single, dual mode. * AST2400 New Static Memory Controller (also referred as FMC) . BMC firmware . New register set . 5 chip select pins (CE0 ∼ CE4) . supports NOR flash, NAND flash and SPI flash memory. . single, dual and quad mode.Each controller has a memory range on which flash devices contents aremapped. Each device is assigned a window that can be changed at bootimewith the Segment Address Registers.Each SPI flash device can then be accessed in two modes: Command andUser. When in User mode, SPI transfers are initiated with accesses tothe memory segment of a device. When in Command mode, memoryoperations on the memory segment of a device generate SPI commandsautomatically using a Control Register for the settings.This initial patch adds support for User mode. Command mode needs a littlemore work to check that the memory window on the AHB bus fits the devicesize. It will come later when support for direct mapping is added.Single and dual mode RX transfers are supported. Other types than SPIare not supported.Reviewed-by: Joel Stanley Tested-by: Joel Stanley Tested-by: Tao Ren Tested-by: Jae Hyun Yoo Signed-off-by: Chin-Ting Kuo Signed-off-by: Cédric Le Goater Link: https://lore.kernel.org/r/20220509175616.1089346-4-clg@kaod.orgSigned-off-by: Mark Brown List of files: /linux-6.15/drivers/mtd/spi-nor/controllers/Makefile

e23e5a05 - mtd: spi-nor: intel-spi: Convert to SPI MEM

Wed, 09 Feb 2022 12:27:05 +0000

mtd: spi-nor: intel-spi: Convert to SPI MEMThe preferred way to implement SPI-NOR controller drivers is through SPIsubsubsystem utilizing the SPI MEM core functions. This converts theIntel SPI flash controller driver over the SPI MEM by moving the driverfrom SPI-NOR subsystem to SPI subsystem and in one go make it use theSPI MEM functions. The driver name will be changed from intel-spi tospi-intel to match the convention used in the SPI subsystem.Signed-off-by: Mika Westerberg Reviewed-by: Andy Shevchenko Reviewed-by: Mauro Lima Reviewed-by: Boris Brezillon Acked-by: Lee Jones Acked-by: Pratyush Yadav Reviewed-by: Tudor Ambarus Link: https://lore.kernel.org/r/20220209122706.42439-3-mika.westerberg@linux.intel.comSigned-off-by: Mark Brown List of files: /linux-6.15/drivers/mtd/spi-nor/controllers/Makefile
