|
* On R-Car Gen2 and Gen3, the AC64 bit (bit 0) of HCCPARAMS1 is set |
|
* to 1. However, these SoCs don't support 64-bit address memory |
|
* pointers. So, this driver clears the AC64 bit of xhci->hcc_params |
|
* to call dma_set_coherent_mask(dev, DMA_BIT_MASK(32)) in |
|
* xhci_gen_setup() by using the XHCI_NO_64BIT_SUPPORT quirk. |
|
* |
|
* And, since the firmware/internal CPU control the USBSTS.STS_HALT |
|
* and the process speed is down when the roothub port enters U3, |
|
* long delay for the handshake of STS_HALT is neeed in xhci_suspend() |
|
* by using the XHCI_SLOW_SUSPEND quirk. |
