Subject: [PATCH] phy: usb: EHCI DMA may lose a burst of DMA data for 7255xA0
family
When the EHCI controller received a 512 byte USB packet that
had to be broken into 2 256 byte bursts across the SCB bus AND
there was a following 512 byte USB packet, the second burst of
data from the first packet was sometimes being lost. If the
burst size was changed to 128 bytes via the EBR_SCB_SIZE field
in the USB_CTRL_EBRIDGE register we'd see the 4th 128 byte burst
of the first packet being lost. This problem became much worse
if other threads were running that accessed memory, like a memcpy
test. Setting the EBR_SCB_SIZE to 512, which prevents breaking
the EHCI USB packet (max size of 512 bytes) into bursts, fixed
the problem.

The BRCM USB Phy, ohci, ehci and xhci drivers all use the USB clocks

Subject: [PATCH] phy: usb: Put USB phys into IDDQ on suspend to save power in
S2 mode
Currently the Phy driver will put the USB phys into the max
power saving mode (IDDQ) when there is no corresponding XHCI, EHCI
or OHCI client (through rmmod, unbind or if the driver is not
builtin). This change will also put the Phys into IDDQ mode
on suspend so that S2 will get the additional power savings.

Subject: [PATCH] phy: usb: Add "wake on" functionality
Add the ability to handle USB wake events from USB devices when
in S2 mode. Typically there is some additional configuration
needed to tell the USB device to generate the wake event when
suspended but this varies with the different USB device classes.
For example, on USB Ethernet dongles, ethtool should be used to
enable the magic packet wake functionality in the dongle.
NOTE: This requires that the "power/wakeup" sysfs entry for
the USB device generating the wakeup be set to "enabled".
This functionality requires a special hardware sideband path that
will trigger the AON_PM_L2 interrupt needed to wake the system from
S2 even though the USB host controllers are in IDDQ (low power state)
and most USB related clocks are shut off. For the sideband signaling
to work we need to leave the usbx_freerun clock running, but this
clock consumes very little power by design. There's a bug in the
XHCI wake hardware so only EHCI/OHCI wake is currently supported.

Subject: [PATCH] phy: usb: Restructure in preparation for adding 7216 USB
support
The driver is being restructured in preparation for adding support
for the new Synopsys USB conroller on the 7216. Since all the bugs
and work-arounds in previous STB chips are supposed to be fixed,
most of the code in phy-brcm-usb-init.c is not needed. Instead of
adding more complexity to the already complicated phy-brcm-usb-init.c
module, the driver will be restructured to use a vector table to
dispatch into different C modules for the different controllers.
There was also some general cleanup done including some ipp setup
code that was incorrect.

Subject: [PATCH] phy: usb: Add support for new Synopsys USB controller on the
7216
The 7216 has the new USB XHCI controller from Synopsys. While
this new controller and the PHY are similar to the STB versions,
the major differences are:
- Many of the registers and fields in the CTRL block have been
removed or changed.
- A new set of Synopsys control registers, BCHP_USB_XHCI_GBL, were
added.
- MDIO functionality has been replaced with direct access registers
in the BCHP_USB_XHCI_GBL block.
- Power up PHY defaults that had to be changed by MDIO in previous
chips will now power up with the correct defaults.
A new init module was created for this new Synopsys USB controller.
A new compatible string was added and the driver will dispatch
into one of two init modules based on it. A "reg-names" field was
added so the driver can more easily get optional registers.
A DT bindings document was also added for this driver.

Subject: [PATCH] phy: usb: Add support for new Synopsys USB controller on the
7211b0
The 7211b0 has added the STB XHCI Synopsys controller and it
will be used instead of the RPi based DWC USB controller. The new
Synopsys XHCI controller core is the same one that is used on the
7216, but because of the way the STB USB PHY is used on both the A0
and B0, some of the PHY control is different.

Subject: [PATCH] phy: usb: PHY's MDIO registers not accessible without device
installed
When there is no device connected and FSM is enabled, the XHCI puts
the PHY into suspend mode. When the PHY is put into suspend mode
the USB LDO powers down the PHY. This causes the MDIO to be
inaccessible and its registers reset to default. The fix is to
disable FSM.

Subject: [PATCH] phy: usb: Add support for wake and USB low power mode for
7211 S2/S5
Add support for 7211 USB wake. Disable all possible 7211 USB logic
for S2/S5 if USB wake is not enabled.
On the 7211, the XHCI wake signal was not connected properly and
only goes to the USB1_USB1_CTRL_TP_DIAG1 diagonstic register.
The workaround is to have VPU code running that polls for the
proper bit in the DIAG register and to wake the system when
the bit is asserted.

Subject: [PATCH] phy: phy-brcm-usb: Constify static structs
A number of structs were not modified and can therefore be made const
to allow the compiler to put them in read-only memory.
In order to do so, update a few functions that don't modify there input
to take pointers to const.
Before:

Changes that require mentioning:
1. interrupt-names
Name "wakeup" was changed to the "wake". It matches example and what
Linux driver looks for in the first place
2. brcm,ipp and brcm,ioc
Both were described as booleans with 0 / 1 values. In examples they
were integers and Linux checks for int as well. Both got uint32.
3. Added minimal description

- If this property is not defined, the phy will default to "host" mode.
-- brcm,syscon-piarbctl: phandle to syscon for handling config registers
-NOTE: one or both of the following two properties must be set

Subject: [PATCH] soc: brcmstb: add stubs for getting platform IDs
Some brcmstb drivers may be shared with other SoC families. E.g. the
same USB PHY block is shared by brcmstb and BCM4908.
To avoid building brcmstb common code on non-brcmstb platforms we need
stubs for:
1. brcmstb_get_family_id()
2. brcmstb_get_product_id()
(to avoid "undefined reference to" errors).
With this change PHY_BRCM_USB will not have to unconditionally select
SOC_BRCMSTB anymore.
