Hello:
Now I use kernel 3.0.21 android version for omap4460 ,but I found mcspi1 control not work which driver is omap2_mcspi.c .Is that right? I modify code as follow:
path:arch/arm/mach-omap2/board-omap4panda.c
OMAP4_MUX(MCSPI1_CS3, OMAP_PIN_OUTPUT | OMAP_MUX_MODE0),
OMAP4_MUX(MCSPI1_CLK, OMAP_PIN_OUTPUT | OMAP_MUX_MODE0),
OMAP4_MUX(MCSPI1_SIMO, OMAP_PIN_OUTPUT | OMAP_MUX_MODE0),
OMAP4_MUX(MCSPI1_SOMI, OMAP_PIN_INPUT| OMAP_MUX_MODE0),

l = mcspi_read_reg(master, OMAP2_MCSPI_MODULCTRL);

MOD_REG_BIT(l, OMAP2_MCSPI_MODULCTRL_SINGLE, 1);
mcspi_write_reg(master, OMAP2_MCSPI_MODULCTRL, l);
Error is :
