+to have information about command/address/dummy bytes in the +transaction register. This information is not relevant for +single mode, and therefore it can have any value in the +allowed range. Therefore, for any read or write transfers of less +than 8 bytes (cmd = 1 byte, addr up to 7 bytes), SPFI will be +configured, but not enabled (unless it is the last transfer in +the queue). The transfer will be enabled by the subsequent tranfer. +A pending transfer is determined by the content of the transaction +register: if command part is set and tsize is not. + +This way we ensure that for dual and quad transactions +the command request size will apear in the command/address part +of the transaction register, while the data size will be in +tsize, all data being sent/received in the same transaction (as +set up in the transaction register). + +Signed-off-by: Ionela Voinescu +Signed-off-by: Ezequiel Garcia +--- + drivers/spi/spi-img-spfi.c | 96 ++++++++++++++++++++++++++++++++++++++++------ + 1 file changed, 85 insertions(+), 11 deletions(-) + +--- a/drivers/spi/spi-img-spfi.c ++++ b/drivers/spi/spi-img-spfi.c +@@ -36,7 +36,8 @@ + #define SPFI_CONTROL_SOFT_RESET BIT(11) + #define SPFI_CONTROL_SEND_DMA BIT(10) + #define SPFI_CONTROL_GET_DMA BIT(9) +-#define SPFI_CONTROL_SE BIT(8) ++#define SPFI_CONTROL_SE BIT(8) ++#define SPFI_CONTROL_TX_RX BIT(1) + #define SPFI_CONTROL_TMODE_SHIFT 5 + #define SPFI_CONTROL_TMODE_MASK 0x7 + #define SPFI_CONTROL_TMODE_SINGLE 0 +@@ -47,6 +48,10 @@ + #define SPFI_TRANSACTION 0x18 + #define SPFI_TRANSACTION_TSIZE_SHIFT 16 + #define SPFI_TRANSACTION_TSIZE_MASK 0xffff ++#define SPFI_TRANSACTION_CMD_SHIFT 13 ++#define SPFI_TRANSACTION_CMD_MASK 0x7 ++#define SPFI_TRANSACTION_ADDR_SHIFT 10 ++#define SPFI_TRANSACTION_ADDR_MASK 0x7 + + #define SPFI_PORT_STATE 0x1c + #define SPFI_PORT_STATE_DEV_SEL_SHIFT 20 +@@ -83,6 +88,7 @@ + */ + #define SPFI_32BIT_FIFO_SIZE 64 + #define SPFI_8BIT_FIFO_SIZE 16 ++#define SPFI_DATA_REQUEST_MAX_SIZE 8 + + struct img_spfi { + struct device *dev;

The DMA request line is tied +to the half full/empty (depending on the use of the TX or RX FIFO) +threshold. For the TX FIFO, if you set a burst size of 8 (equal to +half the depth) the first burst goes into FIFO without any issues, +but due the latency involved (the time the data leaves the DMA +engine to the time it arrives at the FIFO), the DMA might trigger +another burst of 8. But given that there is no space for 2 additonal +bursts of 8, this would result in a failure. Therefore, we have to +keep the burst size for TX to 4 to accomodate for an extra burst. + +For the read (RX) scenario, the DMA request line goes high when +there is at least 8 entries in the FIFO (half full), and we can +program the burst size to be 8 because the risk of accidental burst +does not exist. The DMA engine will not trigger another read until +the read data for all the burst it has sent out has been received. + +While here, move the burst size setting outside of the if/else branches +as they have the same value for both 8 and 32 bit data widths. + +Signed-off-by: Ionela Voinescu +--- + drivers/spi/spi-img-spfi.c | 6 ++---- + 1 file changed, 2 insertions(+), 4 deletions(-) + +--- a/drivers/spi/spi-img-spfi.c ++++ b/drivers/spi/spi-img-spfi.c +@@ -338,12 +338,11 @@ static int img_spfi_start_dma(struct spi + if (xfer->len % 4 == 0) { + rxconf.src_addr = spfi->phys + SPFI_RX_32BIT_VALID_DATA; + rxconf.src_addr_width = 4; +- rxconf.src_maxburst = 4; + } else { + rxconf.src_addr = spfi->phys + SPFI_RX_8BIT_VALID_DATA; + rxconf.src_addr_width = 1; +- rxconf.src_maxburst = 4; + } ++ rxconf.src_maxburst = 8; + dmaengine_slave_config(spfi->rx_ch, &rxconf); + + rxdesc = dmaengine_prep_slave_sg(spfi->rx_ch, xfer->rx_sg.sgl, +@@ -362,12 +361,11 @@ static int img_spfi_start_dma(struct spi + if (xfer->len % 4 == 0) { + txconf.dst_addr = spfi->phys + SPFI_TX_32BIT_VALID_DATA; + txconf.dst_addr_width = 4; +- txconf.dst_maxburst = 4; + } else { + txconf.dst_addr = spfi->phys + SPFI_TX_8BIT_VALID_DATA; + txconf.dst_addr_width = 1; +- txconf.dst_maxburst = 4; + } ++ txconf.dst_maxburst = 4; + dmaengine_slave_config(spfi->tx_ch, &txconf); + + txdesc = dmaengine_prep_slave_sg(spfi->tx_ch, xfer->tx_sg.sgl, diff --git a/target/linux/pistachio/patches-6.1/106-spi-img-spfi-finish-every-transfer-cleanly.patch b/target/linux/pistachio/patches-6.1/106-spi-img-spfi-finish-every-transfer-cleanly.patch new file mode 100644 index 0000000000..ea1f9f28cc --- /dev/null +++ b/target/linux/pistachio/patches-6.1/106-spi-img-spfi-finish-every-transfer-cleanly.patch @@ -0,0 +1,120 @@ +From 5fcca3fd4b621d7b5bdeca18d36dfc6ca6cfe383 Mon Sep 17 00:00:00 2001 +From: Ionela Voinescu +Date: Wed, 10 Aug 2016 11:42:26 +0100 +Subject: spi: img-spfi: finish every transfer cleanly + +Before this change, the interrupt status bit that signaled +the end of a tranfers was cleared in the wait_all_done +function.
