For DTR mode, flexspi only support 8D-8D-8D mode. Patch 1~2 extract nxp_fspi_dll_override(), prepare for adding the DTR mode. in nor suspend, it will disable DTR mode, and enable DTR mode back in nor resume. this require the flexspi driver has the ability to set back to dll override mode in STR mode when clock rate < 100MHz. Patch 3 Add the DDR LUT command support. flexspi use LUT command to handle the dtr/str mode. Patch 4 add the logic of sample clock source selection for STR/DTR mode STR use the default mode 0, sample based on the internal dummy pad. DTR use the mode 3, sample based on the external DQS pad, so this board and device connect the DQS pad. adjust the clock rate for DTR mode, when detect the DDR LUT command, flexspi will automatically div 2 of the root clock and output to device. Patch 5 finally add the DTR support in default after the upper 4 patches's prepareation. Since lx2160a do not implement DQS pad, so can't support this DTR mode. Signed-off-by: Haibo Chen --- Changes in v2: - split the original PATCH 1 into two patches. - PATCH 3 put the ?: in one line and add Frank Li's reviewed tag. - combine the original PATCH3 and PATCH4, and simplify the code logic according to Frank's suggestion. - rename nxp_fspi_mem_caps_quirks to nxp_fspi_mem_caps_disable_dtr. - Link to v1: https://lore.kernel.org/r/20250916-flexspi-ddr-v1-0-69358b5dc862@nxp.com --- Haibo Chen (5): spi: spi-nxp-fspi: extract function nxp_fspi_dll_override() spi: spi-nxp-fspi: set back to dll override mode when clock rate < 100MHz spi: spi-nxp-fspi: Add the DDR LUT command support spi: spi-nxp-fspi: add the support for sample data from DQS pad spi: spi-nxp-fspi: Add OCT-DTR mode support drivers/spi/spi-nxp-fspi.c | 115 ++++++++++++++++++++++++++++++++++++++------- 1 file changed, 98 insertions(+), 17 deletions(-) --- base-commit: c3067c2c38316c3ef013636c93daa285ee6aaa2e change-id: 20250916-flexspi-ddr-f841f3d79aef Best regards, -- Haibo Chen
