This patch is to correct the bit mapping of "MORE" and "CTS" in SPI frame header. Per SPI protocol, SPI header is encoded with length of 4 byte, which is defined as below: bit 0 ~ 11: current data size; bit 12: "MORE" bit; bit 13: reserve bit 14 ~ 15: reserve bit 16 ~ 27: next data size bit 28: RI bit 29: DCD bit 30: CTS/RTS bit 31: DSR/DTR According to above SPI header structure, the bit mapping of "MORE" and "CTS" is incorrect in function ifx_spi_decode_spi_header(); cc: Chen Jun <jun.d.chen@xxxxxxxxx> Signed-off-by: channing <chao.bi@xxxxxxxxx> --- drivers/tty/serial/ifx6x60.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/tty/serial/ifx6x60.c b/drivers/tty/serial/ifx6x60.c index 5b9bc19..60e767f 100644 --- a/drivers/tty/serial/ifx6x60.c +++ b/drivers/tty/serial/ifx6x60.c @@ -64,8 +64,8 @@ #include "ifx6x60.h" #define IFX_SPI_MORE_MASK 0x10 -#define IFX_SPI_MORE_BIT 12 /* bit position in u16 */ -#define IFX_SPI_CTS_BIT 13 /* bit position in u16 */ +#define IFX_SPI_MORE_BIT 4 /* bit position in u8 */ +#define IFX_SPI_CTS_BIT 6 /* bit position in u8 */ #define IFX_SPI_MODE SPI_MODE_1 #define IFX_SPI_TTY_ID 0 #define IFX_SPI_TIMEOUT_SEC 2 -- 1.7.1 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
