usb: mtu3: fix the wrong HS mult value

2021-09-12T07:00:59Z

commit 44e4439d8f9f8d0e9da767d1f31e7c211081feca upstream. usb_endpoint_maxp() returns actual max packet size, @mult will always be zero, fix it by using usb_endpoint_maxp_mult() instead to get mult.

2021-09-12T07:00:59Z

commit fd7cb394ec7efccc3985feb0978cee4d352e1817 upstream. For HS isoc or intr, should use @mult but not @burst to save mult value.

usb: mtu3: use clock bulk to get clocks

2021-06-15T13:46:45Z

Use clock bulk helpers to get/enable/disable clocks, meanwhile make sys_ck optional, then will be easier to handle clocks. Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/1623139069-8173-24-git-send-email-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman

usb: mtu3: rebuild role switch get/set hooks

Use common helper ssusb_set_mode() to do role switch instead of manual switch helper; Remove unnecessary local variable when get role status Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/1623139069-8173-14-git-send-email-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman

usb: mtu3: use force mode for dual role switch

2021-06-15T13:43:50Z

Force IDDIG status for all three ways of dual role switch, this is needed when use Type-C to switch mode. Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/1623139069-8173-13-git-send-email-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman

This is a preparation patch to plan to use the same work to handle role switch for all three supported ways. Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/1623139069-8173-11-git-send-email-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman

usb: mtu3: use enum usb_role instead of private defined ones

2021-06-15T13:43:11Z

Now we mainly use usb-role-switch to set dual role mode, and all three ways supported use the same function to switch mode, use usb_role enum will make code clear Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/1623139069-8173-10-git-send-email-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman
