The I2C-1 bus frequency on zoom2/zoom3/sdp3630 should be 2.4 MHz. The speed is limited by TWL5030/GAIA; a higher speed could lead to errors on the interface. The maximum I2C speed depends on the system clock for GAIA: 2.2 MHz (sys-clk = 19.2 MHz) 2.4 MHz (sys-clk = 26 MHz) 2.9 MHz (sys-clk = 38.4 MHz) For Zoom2/Zoom3/SDP3630 the system clock is 26Mhz and hence choose 2.4Mhz for I2C1 bus speed Signed-off-by: Vikram Pandita <vikram.pandita@xxxxxx> --- arch/arm/mach-omap2/board-zoom-peripherals.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) mode change 100644 => 100755 arch/arm/mach-omap2/board-zoom-peripherals.c diff --git a/arch/arm/mach-omap2/board-zoom-peripherals.c b/arch/arm/mach-omap2/board-zoom-peripherals.c old mode 100644 new mode 100755 index 4ca9c20..54619d5 --- a/arch/arm/mach-omap2/board-zoom-peripherals.c +++ b/arch/arm/mach-omap2/board-zoom-peripherals.c @@ -235,7 +235,7 @@ static struct twl4030_platform_data zoom_twldata = { static struct i2c_board_info __initdata zoom_i2c_boardinfo[] = { { - I2C_BOARD_INFO("twl4030", 0x48), + I2C_BOARD_INFO("twl5030", 0x48), .flags = I2C_CLIENT_WAKE, .irq = INT_34XX_SYS_NIRQ, .platform_data = &zoom_twldata, @@ -244,7 +244,7 @@ static struct i2c_board_info __initdata zoom_i2c_boardinfo[] = { static int __init omap_i2c_init(void) { - omap_register_i2c_bus(1, 2600, zoom_i2c_boardinfo, + omap_register_i2c_bus(1, 2400, zoom_i2c_boardinfo, ARRAY_SIZE(zoom_i2c_boardinfo)); omap_register_i2c_bus(2, 400, NULL, 0); omap_register_i2c_bus(3, 400, NULL, 0); -- 1.6.5.1.69.g36942 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
