Subject: [PATCH v2 0/5] Mediatek xHCI support
Date: Wed, 8 Jul 2015 17:41:02 +0800 [thread overview]
Message-ID: <1436348468-4126-1-git-send-email-chunfeng.yun@mediatek.com> (raw)
The patch supports MediaTek's xHCI controller.
There are some differences from xHCI spec:
1. The interval is specified in 250 * 8ns increments for Interrupt Moderation
Interval(IMODI) of the Interrupter Moderation(IMOD) register, it is 8 times as
much as that defined in xHCI spec.
2. For the value of TD Size in Normal TRB, MTK's xHCI controller defines a
number of packets that remain to be transferred for a TD after processing all
Max packets in all previous TRBs,that means don't include the current TRB's,
but in xHCI spec it includes the current ones.
3. To minimize the scheduling effort for synchronous endpoints in xHC, the MTK
architecture defines some extra SW scheduling parameters for HW. According to
these parameters provided by SW, the xHC can easily decide whether a
synchronous endpoint should be scheduled in a specific uFrame. The extra SW
scheduling parameters are put into reserved DWs in Slot and Endpoint Context.
And a bandwidth scheduler algorithm is added to support such feature.
A usb3.0 phy driver is also added which used by mt65xx SoCs platform, it
supports two usb2.0 ports and one usb3.0 port.
Change in v2:
1. Rebase to 4.2-rc1
2. Remove probe phy before add usb_hcd patch from this series due to 4.2-rc1
already fix this issue
3. add xhci mac clocks
4. add suspend/resume
5. support remote wakeup
