From: Constantine Shulyupin <co...@makelinux.com> Call USB initialization davinci_setup_usb from board initialization dm365_evm_init.
Tested with OTG configuration, usb gadget g_zero on DM365 EVM connected to PC. Note: register USB_PHY_CTRL must have flag USBPHY_CLKFREQ_24MHZ References: Original patch by miguel.agui...@ridgerun.com three years ago: - http://www.mail-archive.com/davinci-linux-open-source@linux.davincidsp.com/msg14741.html Signed-off-by: Constantine Shulyupin <co...@makelinux.com> --- Changelog Changes since v6 - patch splitted accordinly request of Sergei - this split contains call to davinci_setup_usb from dm365_evm_init Changes since v5 http://www.spinics.net/lists/kernel/msg1413120.html accordingy feedback of nsek...@ti.com http://www.spinics.net/lists/kernel/msg1414914.html - phy configuration moved to drivers/usb/musb/davinci.c - USB_OTG configuration is submitted in separated patch: http://www.spinics.net/lists/kernel/msg1414964.html - Setting current limit to 1000 mA.
