[PATCH/RFC] usb: dwc2: awake rt305x USB controller

From: Serge Vasilugin The Ralink uboot sets the USB controller into sleep mode. This patch checks this condition and awakes controller before any register access. Signed-off-by: Serge Vasilugin Signed-off-by: John Crispin --- Hi, we have been carrying this patch inside OpenWrt for half a

[PATCH] usb: make the MTK XHCI driver compile for older MIPS SoCs

The MIPS based MT7621 shares the same XHCI core as the newer generation of ARM based SoCs. The driver works out of the box and we only need to make it buildable in Kconfig. Signed-off-by: John Crispin --- drivers/usb/host/Kconfig |4 ++-- 1 file changed, 2 insertions(+), 2 deletions

Re: [PATCH v2 4/5] xhci: mediatek: support MTK xHCI host controller

Hi there is a cross dependency between the modules. xhci-mtk.ko requires xhci.ko to be loaded. however this will look for xhci_mtk_add_ep_quirk() which is part of xhci-mtk. the modules will build but are not run time loadable. John On 08/07/2015 11:41, Chunfeng Yun wrote: > MTK xhci host

[PATCH V2] USB: dwc2: add support for the reset_controller api

We need this for dwc2 to work on older ralink SoC like the rt3052. Without, we see the following when loading the driver: [0.76] dwc2 101c.usb: Bad value for GSNPSID: 0x Signed-off-by: John Crispin --- Changes since V1 * move the OF lookup call into the platform code * add

Re: dwc2: Invalid (?) initialization of PCGCTL register

Hi, Simply resetting the PCGCTL register in hcd_init or somewhere around there fixes the problem. However, John suggested an even more generic problem: using the kernel-wide reset controller driver to completely reset the dwc controller before initializing it (by calling device_reset()). On the
