Both are mandatory. It uses different transfer type bits in IFR register. It has dedicated registers to specify a read or a write instruction: Read Instruction Code Register (RICR) and Write Instruction Code Register (WICR). ICR/RICR/WICR have identical fields. Tested with sst26vf064b jedec,spi-nor flash. Backward compatibility test done on sama5d2 qspi controller and mx25l25635e jedec,spi-nor flash. Signed-off-by: Tudor Ambarus Reviewed-by: Boris Brezillon --- v6: add a caps instance to the sama5d2 entry instead of allowing caps to be NULL v5: - use WICR for sam9x60 - remove ops hooks and introduce caps->has_ricr - get rid of the cfg struct - group IO accesses together in atmel_qspi_set_cfg() v4: - drop local variables that kept aq->regs and &pdev->dev, the compiler should be smart enough to store them in a register - add comment saying QSPI_IFR_APBTFRTYP_READ is defined in sam9x60 - s/sama5d2_qspi_modes/atmel_qspi_modes, modes are the same both controllers - fix kernel doc header - move comment in function body v3: - reorganize the code and change ops functions pointers to avoid code duplication. From the IP perspective, the transfer type bits are different, and what registers are written: ricr/wicr instead of icr. - treat just regular spi transfers. Mem transfers will be added together with dirmap support. v2: - rework clock handling - reorder setting of register values in set_cfg() calls -> move functions that can fail in the upper part of the function body. drivers/spi/atmel-quadspi.c | 163 ++++++++++++++++++++++++++++++++++---------- 1 file changed, 128 insertions(+), 35 deletions(-) diff --git a/drivers/spi/atmel-quadspi.c b/drivers/spi/atmel-quadspi.c index 336501d962e5..fffc21cd5f79 100644 --- a/drivers/spi/atmel-quadspi.c +++ b/drivers/spi/atmel-quadspi.c @@ -19,6 +19,7 @@ #include #include #include +#include #include #include @@ -35,7 +36,9 @@ #define QSPI_IAR 0x0030 /* Instruction Address Register */ #define QSPI_ICR 0x0034 /* Instruction Code Register */ +#define QSPI_WICR 0x0034 /* Write Instruction Code Register */ #define QSPI_IFR 0x0038 /* Instruction Frame Register */ +#define QSPI_RICR 0x003C /* Read Instruction Code Register */ #define QSPI_SMR 0x0040 /* Scrambling Mode Register */ #define QSPI_SKR 0x0044 /* Scrambling Key Register */ @@ -88,7 +91,7 @@ #define QSPI_SCR_DLYBS_MASK GENMASK(23, 16) #define QSPI_SCR_DLYBS(n) (((n) << 16) & QSPI_SCR_DLYBS_MASK) -/* Bitfields in QSPI_ICR (Instruction Code Register) */ +/* Bitfields in QSPI_ICR (Read/Write Instruction Code Register) */ #define QSPI_ICR_INST_MASK GENMASK(7, 0) #define QSPI_ICR_INST(inst) (((inst) << 0) & QSPI_ICR_INST_MASK) #define QSPI_ICR_OPT_MASK GENMASK(23, 16) @@ -118,6 +121,7 @@ #define QSPI_IFR_CRM BIT(14) #define QSPI_IFR_NBDUM_MASK GENMASK(20, 16) #define QSPI_IFR_NBDUM(n) (((n) << 16) & QSPI_IFR_NBDUM_MASK) +#define QSPI_IFR_APBTFRTYP_READ BIT(24) /* Defined in SAM9X60 */ /* Bitfields in QSPI_SMR (Scrambling Mode Register) */ #define QSPI_SMR_SCREN BIT(0) @@ -133,12 +137,18 @@ #define QSPI_WPSR_WPVSRC_MASK GENMASK(15, 8) #define QSPI_WPSR_WPVSRC(src) (((src) << 8) & QSPI_WPSR_WPVSRC) +struct atmel_qspi_caps { + bool has_qspick; + bool has_ricr; +}; struct atmel_qspi { void __iomem *regs; void __iomem *mem; struct clk *pclk; + struct clk *qspick; struct platform_device *pdev; + const struct atmel_qspi_caps *caps; u32 pending; u32 mr; struct completion cmd_completion; @@ -151,7 +161,7 @@ struct atmel_qspi_mode { u32 config; }; -static const struct atmel_qspi_mode sama5d2_qspi_modes[] = { +static const struct atmel_qspi_mode atmel_qspi_modes[] = { { 1, 1, 1, QSPI_IFR_WIDTH_SINGLE_BIT_SPI }, { 1, 1, 2, QSPI_IFR_WIDTH_DUAL_OUTPUT }, { 1, 1, 4, QSPI_IFR_WIDTH_QUAD_OUTPUT }, @@ -180,8 +190,8 @@ static int atmel_qspi_find_mode(const struct spi_mem_op *op) { u32 i; - for (i = 0; i < ARRAY_SIZE(sama5d2_qspi_modes); i++) - if (atmel_qspi_is_compatible(op, &sama5d2_qspi_modes[i])) + for (i = 0; i < ARRAY_SIZE(atmel_qspi_modes); i++) + if (atmel_qspi_is_compatible(op, &atmel_qspi_modes[i])) return i; return -ENOTSUPP; @@ -201,36 +211,37 @@ static bool atmel_qspi_supports_op(struct spi_mem *mem, return true; } -static int atmel_qspi_exec_op(struct spi_mem *mem, const struct spi_mem_op *op) +static int atmel_qspi_set_cfg(struct atmel_qspi *aq, + const struct spi_mem_op *op, u32 *offset) { - struct atmel_qspi *aq = spi_controller_get_devdata(mem->spi->master); - int mode; + u32 iar, icr, ifr; u32 dummy_cycles = 0; - u32 iar, icr, ifr, sr; - int err = 0; + int mode; iar = 0; icr = QSPI_ICR_INST(op->cmd.opcode); ifr = QSPI_IFR_INSTEN; - /* - * If the QSPI controller is set in regular SPI mode, set it in - * Serial Memory Mode (SMM). - */ - if (aq->mr != QSPI_MR_SMM) { - writel_relaxed(QSPI_MR_SMM, aq->regs + QSPI_MR); - aq->mr = QSPI_MR_SMM; - } - mode = atmel_qspi_find_mode(op); if (mode < 0) return mode; - - ifr |= sama5d2_qspi_modes[mode].config; + ifr |= atmel_qspi_modes[mode].config; if (op->dummy.buswidth && op->dummy.nbytes) dummy_cycles = op->dummy.nbytes * 8 / op->dummy.buswidth; + /* + * The controller allows 24 and 32-bit addressing while NAND-flash + * requires 16-bit long.
