PATCH 1/3 There is a conditional if statement for the usb clock to be 60MHz +/-1kHz in the mxc gadget driver, this requirement is not needed on mx51 because the usb core is clocked at 66.5MHz or any other frequency that are not multiples of 60MHz. PATCH 2/3 PLL3 can be used for TVE output and/or USB. No need to turn on a whole PLL just for USB. Using PLL2 is a better source for the usb clock. PATCH 3/3 Defines device structure for gadget on OTG port and registers it in the board file. Defines the appropriate clock. Defines KCONFIG option for enabling OTG port for EHCI or Gadget. Conditionalizes the OTG port for EHCI or Gadget feature. git diff --stat for all 3 patches: arch/arm/mach-mx5/board-mx51_babbage.c | 11 +++++++++++ arch/arm/mach-mx5/clock-mx51.c | 4 +++- arch/arm/mach-mx5/devices.c | 12 ++++++++++++ arch/arm/mach-mx5/devices.h | 1 + drivers/usb/gadget/fsl_mx3_udc.c | 14 ++++++++------ drivers/usb/host/Kconfig | 8 ++++++++ 6 files changed, 43 insertions(+), 7 deletions(-) Thanks, Dinh Nguyen ^ permalink raw reply [flat|nested] 7+ messages in thread

Have a look at arch/arch/mach-mx2/mach-pca100.c how this is done. As a side effect you get rid of the 'defined but not used' warnings this patch introduces and you don't have to put platform related kconfig options to a totally unrelated place.

The only thing this patch changes is that when usboh3_clk is enabled, pll2 instead of pll3 gets enabled. The real parent of this clock is defined by the status quo of the CSCMR1/usboh3_clk_sel bits. So the solution here is to initialize the parent field during runtime according to the bits in hardware or to change the hardware bits according to the parent field. Either way, please make sure that hardware and state of the clock tree are consistent.
