Since the following patch was too late to get into 2.6.38, it now should be applied to 2.6.38.y. It has already hit mainline in 2.6.39-rc1...
---------- Forwarded Message ---------- Subject: [PATCH] DM644x EVM: register MUSB device earlier Date: Sunday 13 March 2011 From: Sergei Shtylyov <[email protected]> To: [email protected], [email protected], [email protected] The MUSB driver doesn't see its platform device on DM644x EVM board anymore since commit 73b089b052a69020b953312a624a6e1eb5b81fab (usb: musb: split davinci to its own platform_driver) because the new probe is called as subsys_initcall() now, and the device is registered later than that by the board code. Move the registration to davinci_evm_init() -- it's safe to do so because the MUSB core device still gets initialized as fs_initcall() -- which is late enough for the I2C GPIO expander (which controls VBUS) to be initialized. Signed-off-by: Sergei Shtylyov <[email protected]> --- The patch is against the recent DaVinci tree. It fixes post 2.6.38-rc1 regression, so should be applied immediately! arch/arm/mach-davinci/board-dm644x-evm.c | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) Index: linux-davinci/arch/arm/mach-davinci/board-dm644x-evm.c =================================================================== --- linux-davinci.orig/arch/arm/mach-davinci/board-dm644x-evm.c +++ linux-davinci/arch/arm/mach-davinci/board-dm644x-evm.c @@ -440,11 +440,6 @@ evm_u35_setup(struct i2c_client *client, gpio_request(gpio + 7, "nCF_SEL"); gpio_direction_output(gpio + 7, 1); - /* irlml6401 switches over 1A, in under 8 msec; - * now it can be managed by nDRV_VBUS ... - */ - davinci_setup_usb(1000, 8); - return 0; } @@ -705,6 +700,9 @@ static __init void davinci_evm_init(void davinci_serial_init(&uart_config); dm644x_init_asp(&dm644x_evm_snd_data); + /* irlml6401 switches over 1A, in under 8 msec */ + davinci_setup_usb(1000, 8); + soc_info->emac_pdata->phy_id = DM644X_EVM_PHY_ID; /* Register the fixup for PHY on DaVinci */ phy_register_fixup_for_uid(LXT971_PHY_ID, LXT971_PHY_MASK, ------------------------------------------------------- _______________________________________________ stable mailing list [email protected] http://linux.kernel.org/mailman/listinfo/stable
