| * | | | edid: rename struct member to fix two EDID_* macrosChristian Gmeiner2013-08-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this change EDID_DETAILED_TIMING_VSYNC_OFFSET and EDID_DETAILED_TIMING_VSYNC_PULSE_WIDTH macros can not be used (compile error). The fix is quite trivial: rename struct member to the expected name. Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case only the CONFIG_SYS_I2C_SPEED is set in configuration file, the CONFIG_SYS_I2C_SOFT_SPEED is defined as CONFIG_SYS_I2C_SPEED. The CONFIG_SYS_I2C_SOFT_SPEED is then used throughout the driver. Unfortunatelly, due to a typo in the driver, instead of defining CONFIG_SYS_I2C_SOFT_SPEED, an CONFIG_SYS_SOFT_I2C_SPEED was defined and therefore the driver failed to compile. The same applies for CONFIG_SYS_I2C_SOFT_SLAVE , where the swap happens as well. This patch fixes the issue. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Heiko Schocher <hs@denx.de>

Leverage this and make use of this value as this makes the code mode universal, but also gets us rid of the CONFIG_USB_REG_BASE configuration option. Moreover, this patch cleans up the usb_gadget_register_driver() call a little by correcting the error handling. Note the usb_lowlevel_init() and mvudc_probe() are now called in reversed order, but this has no impact on the code.

These functions are defined with a weak attribute in drivers/mtd/cfi_flash.c. This means they can be overrided by board-specific ones if necessary. When defining such functions under board/ directory or somewhere, cfi_flash.h should be included. This makes sure that board-specfic cfi functions are defined in a correct prototype.
