Following changes are made to the Lantiq kernel patches: 0001-MIPS-lantiq-add-pcie-driver.patch The pci header isn't included by the of_pci header any longer 0024-MIPS-lantiq-revert-DSA-switch-driver-PMU-clock-chang.patch Due to the merge of grx390 and ar10 clocks, extend support to grx390 0025-NET-MIPS-lantiq-adds-xrx200-legacy.patch The do_carrier arguments was dropped from phy_link_change. The phylib has always sets the third parameter to true so the flag is always changed anyway. of_get_phy_mode() returns an error, or 0 on success, and pass a pointer, of type phy_interface_t, where the phy mode should be stored now. So far an error wasn't considered. Print at least an error message if something unexpected happens. The stuck queue is now passed to xrx200_tx_timeout (the timeout handler) but not used so far. 0028-NET-lantiq-various-etop-fixes.patch ioremap has provided non-cached semantics by default since the Linux 2.6 days and was removed with kernel version 5.6. of_get_phy_mode() returns an error, or 0 on success, and pass a pointer, of type phy_interface_t, where the phy mode should be stored now. So far an error wasn't considered. Print at least an error message if something unexpected happens. 0042-arch-mips-increase-io_space_limit.patch Move IO space extension to laniq specific file Signed-off-by: Mathias Kresin <dev@kresin.me>

Subject: [PATCH 2/2] usb: dwc2: add support for other Lantiq SoCs
|
|
|
|
The size of the internal RAM of the DesignWare USB controller changed
|
|
between the different Lantiq SoCs. We have the following sizes:
|
|
|
|
Amazon + Danube: 8 KByte
|
|
Amazon SE + arx100: 2 KByte
|
|
xrx200 + xrx300: 2.5 KByte
|
|
|
|
For Danube SoC we do not provide the params and let the driver decide
|
|
to use sane defaults, for the Amazon SE and arx100 we use small fifos
|
|
and for the xrx200 and xrx300 SCs a little bit bigger periodic fifo.
|
|
The auto detection of max_transfer_size and max_packet_count should
|
|
work, so remove it.
