We can remove the ifdefs by setting up helper functions for mentor DMA and cppi/tusb DMA. Note that I've kept the existing formatting as otherwise this patch becomes pretty much unreadable. Signed-off-by: NTony Lindgren <tony@atomide.com> Signed-off-by: NFelipe Balbi <balbi@ti.com>

Let's get rid of the horrible ifdef in middle of the expression. We can do it by adding a variable for short_packet and testing it separately for DMA related code. Signed-off-by: NTony Lindgren <tony@atomide.com> Signed-off-by: NFelipe Balbi <balbi@ti.com>

Pass struct musb to tusb_dma_omap() and is_cppi_enabled(), and add macros for the other DMA controllers. Populate the platform specific quirks with the DMA type and use it during runtime. Note that platform glue layers with no custom DMA code are tagged with MUSB_DMA_INVENTRA which may have a chance of working. Looks like the defconfigs for these use PIO_ONLY, so this should not break existing configs. Signed-off-by: NTony Lindgren <tony@atomide.com> Signed-off-by: NFelipe Balbi <balbi@ti.com>

During vbus session, usb controller needs to exit hibernation if it was previously in suspend state. Since controller will be resetted and configured, there is no need to restore registers. Moreover, set lx_state to L0 on B session. vbus_session callback may not be used by all platforms. Thus, controller software state needs to be set to L0 if the controller detects a valid B session. Otherwise, lx_state will remain L2 and prevent any request submission.

AMD CPUs don't reinitialize the SS descriptor on SYSRET, so SYSRET with SS == 0 results in an invalid usermode state in which SS is apparently equal to __USER_DS but causes #SS if used. Work around the issue by setting SS to __KERNEL_DS __switch_to, thus ensuring that SYSRET never happens with SS set to NULL. This was exposed by a recent vDSO cleanup.
