From: "Govindraj.R" <govindraj.raja@xxxxxx> On omap3630 onwards uart wer reg has bit 7 for tx wakeup enable. Without this bit set some uart sluggishness might be seen while printing data on console, response is better when enabling this bit. Tested with Beagle XM (OMAP3630) Cc: Kevin Hilman <khilman@xxxxxx> Cc: Paul Walmsley <paul@xxxxxxxxx> Signed-off-by: Govindraj.R <govindraj.raja@xxxxxx> --- But on omap3430 the bit is not available. arch/arm/plat-omap/include/plat/omap-serial.h | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/arch/arm/plat-omap/include/plat/omap-serial.h b/arch/arm/plat-omap/include/plat/omap-serial.h index 9ff4444..0c22d8d 100644 --- a/arch/arm/plat-omap/include/plat/omap-serial.h +++ b/arch/arm/plat-omap/include/plat/omap-serial.h @@ -39,7 +39,7 @@ /* WER = 0x7F * Enable module level wakeup in WER reg */ -#define OMAP_UART_WER_MOD_WKUP 0X7F +#define OMAP_UART_WER_MOD_WKUP 0xFF /* Enable XON/XOFF flow control on output */ #define OMAP_UART_SW_TX 0x04 -- 1.7.5.4 -- 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
