According to the dwc2 programmer's guide v3.10a, in '2.1.3.2 Dedicated
FIFO Mode with No Thresholding', it suggested that:
Device RxFIFO =
- Scatter/Gather DMA mode:
(4 * number of control endpoints + 6) + ((largest USB packet used / 4) +
1 for status information) + (2 * number of OUT endpoints) + 1 for Global NAK
on rockchip platforms:
(4 * 1 + 6) + ((1024 / 4) + 1) + (2 * 6) + 1 = 280
- Slave or Buffer DMA mode:
(5 * number of control endpoints + 8) + ((largest USB packet used / 4) +
1 for status information) + (2 * number of OUT endpoints) + 1 for Global NAK
on rockchip platforms:
(5 * 1 + 8) + ((1024 / 4) + 1) + (2 * 6) + 1 = 283
Device IN Endpoint TxFIFO =
The TxFIFO must equal at least one MaxPacketSize (MPS).
In addition to RxFIFO and TxFIFOs, refer to dwc2 databook v3.10a,
'Figure 2-13 Device Mode FIFO Address Mapping and AHB FIFO Access Mapping
(Dedicated FIFO)', it required that when the device is operating in non
Scatter Gather Internal DMA mode, the last locations of the SPRAM are used
to store the DMAADDR values for each Endpoint (1 location per endpoint).
When the device is operating in Scatter Gather mode, then the last locations
of the SPRAM store the Base Descriptor address, Current Descriptor address,
Current Buffer address, and status quadlet information for each endpoint
direction (4 locations per Endpoint). If an Endpoint is bidirectional , then
4 locations will be used for IN, and another 4 for OUT).
Considering that the total FIFO size of dwc2 otg is 0x3cc (972),
and we must reserve (4 * 13) = 52 locations for all Endpoints.
So reconfig dwc2 device fifo size as follows:
Device RxFIFO = 280
Device IN Endpoint TxFIFO
- FIFO #0 = (64 / 4) = 16 (Assuming this is used for EP0)
- FIFO #1 = (1024/4) = 256 (Assuming this is used for Isochronous)
- FIFO #2 = (512/4) = 128
- FIFO #3 = (512/4) = 128
- FIFO #4 = (256/4) = 64
- FIFO #5 = (128/4) = 32
- FIFO #6 = (64/4) = 16
After reconfig the dwc2 device fifo size, test mtp write on rockchip
platform (PC -> rockchip platform) on rk312x/rk3326/px30/rk3288 evb,
when mask the 'vfs_write' in f_mtp.c, the writing data rate can be
increased from 16MBps ~ 20MBps to 30MBps ~ 36MBps on different kinds
of rockchip evbs.

If more than two consecutive requests queue into in ep, maybe some
requests need alloc temporary aligned buffer, only the first request
will do memory copy to the aligned buffer, but start_next_request()
function missing memory copy, then the transmission of data will be
wrong, so do memory copy after alloc aligned buffer right away.

Limit the max size of aligned buffer to 64K. Because
64K buffer is enough for most of usb transfers, and
the aligned buffer is a coherent DMA buffer allocated
by dma_alloc_coherent, too large buffer may cause
coherent DMA memory allocation failure on some platforms.

case 1:
plug in hdmi and power on, after kernel complete and before android
start(maybe can update simplification boot.img) we plug out hdmi will
appear error log.
case 2:
plug in hdmi and power on, at the beginning of drm driver bind, plug out
hdmi, the hdmi irq maybe at disable state, so the vop is in running
state which is set at uboot. in this case vop will not to enable clk
refrerence, after driver probe complete, the unused clk maybe close by
clk driver framework. this will lead to vop appear error log:

[ 4.900174] rockchip-vop ff370000.vop: [drm:vop_isr] *ERROR*BUS_ERROR irq err
solution:
1. disable vop all planes before disable crtc and enable crtc;
2. disable vop all planes when can't detect connect at power on.
3. enable dma stop before detach iommu and disable dma stop after attach
iommu.

enable this function in dts file, such as:

fusb302,try_role = "ROLE_MODE_DFP";
It would change the port power role to your wanted

This patch supports fusb302 to do data role swap for
Type-C Dongle with PD adapter.
The test case is:
- Use a Type-C Dongle (PD adapter & USB & HDMI)
- Plug a PD adapter into Type-C Dongle first, then
connect the Dongle with RK3399 Type-C0 port.
- Check if Type-C Dongle can fetch 5V with the following log:
"fusb302 4-0022: PD connected as UFP, fetching 5V"
- Wait for the data role swap completion (hundreds of
milliseconds), then check if the Type-C USB can work
in DFP mode.
Without this patch, the DWC3 can't switch to DFP mode
after the data role swap completion. It's because that
when the fusb302 do data role swap, it only sends extcon
notifier with EXTCON_USB true or EXTCON_USB_HOST true.
Generally, the sequence of the extcon notifier sent from
fusb302 is:
- send "EXTCON_USB = true" and "EXTCON_USB_HOST=false"
to DWC3 driver, then DWC3 switch to UFP, and set the
connected flag to true.
- After swap completion, send "EXTCON_USB = false" and
"EXTCON_USB_HOST = true" to DWC3 driver. Because the
connected flag is true, the DWC3 is unable to switch
to DFP mode.
This patch forces DWC3 to do disconnection if it detects
the connected flag is true and the DWC3 mode is UFP.
