I found that there was bug in the USB source clock in the DM365 baseport. I have sent 1 patch to address that and the patch below is to enable USB on the Dm365 EVM.
For USB to actually work on the Dm365 based on the current implementation, we need to update the USB driver with cpu_is_davinci_dm365 functions which is an absolute no-no. In any case as I understand from e-mails on the mailing list that is going to be updated soon > -----Original Message----- > From: Paulraj, Sandeep > Sent: Thursday, August 27, 2009 4:43 PM > To: [email protected] > Cc: Paulraj, Sandeep > Subject: [PATCH] DaVinci:DM365: Enable USB in DM365 EVM > > From: Sandeep Paulraj <[email protected]> > > This patch enables USB on the DM365 EVM > > Signed-off-by: Sandeep Paulraj <[email protected]> > --- > arch/arm/mach-davinci/board-dm365-evm.c | 14 ++++++++++++++ > 1 files changed, 14 insertions(+), 0 deletions(-) > > diff --git a/arch/arm/mach-davinci/board-dm365-evm.c b/arch/arm/mach- > davinci/board-dm365-evm.c > index f6adf79..e43933f 100644 > --- a/arch/arm/mach-davinci/board-dm365-evm.c > +++ b/arch/arm/mach-davinci/board-dm365-evm.c > @@ -24,6 +24,8 @@ > #include <linux/mtd/mtd.h> > #include <linux/mtd/partitions.h> > #include <linux/mtd/nand.h> > +#include <linux/gpio.h> > + > #include <asm/setup.h> > #include <asm/mach-types.h> > #include <asm/mach/arch.h> > @@ -270,6 +272,16 @@ static void dm365evm_mmc_configure(void) > davinci_cfg_reg(DM365_SD1_DATA0); > } > > +static void dm365evm_usb_configure(void) > +{ > + davinci_cfg_reg(DM365_GPIO33); > + > + gpio_request(33, "usb"); > + gpio_direction_output(33, 1); > + > + setup_usb(500, 8); > +} > + > static void __init evm_init_i2c(void) > { > davinci_init_i2c(&i2c_pdata); > @@ -476,6 +488,8 @@ static __init void dm365_evm_init(void) > > /* maybe setup mmc1/etc ... _after_ mmc0 */ > evm_init_cpld(); > + > + dm365evm_usb_configure(); > } > > static __init void dm365_evm_irq_init(void) > -- > 1.6.0.4 _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
