2022-01-27cad(4): Disable unused priority queuesVisa Hankala
The GEMs on the PolarFire Soc implement four Rx queues and four Tx queues for prioritizing traffic. All the queues are in a pseudo active state after reset. The driver uses only queues with index 0. Disable the rest to avoid DMA errors. Tested on a SiFive FU740 by jca@, Microchip PolarFire SoC and Xilinx Zynq-7000 by me.
2022-01-18Improve how quirks are handled on sdhc(4)-compatible drivers. So farPatrick Wildt
we have passed a modified version of the contents in the capabilities register if we wanted to override what sdhc(4) would otherwise read. Unfortunately there's a second capabilities register that we did not yet take into consideration, which is why to disable DDR50 support we created a quirk flag in the softc. The sdhc(4) ACPI nodes have a way to mask and set bits in both of the capabilities register, which is a flexible approach to solving that issue and using that for our sdhc(4) drivers even improves readability. ok kettenis@

2022-01-08Apply mpsafe changes from dwge(4) to dwxe(4):Jonathan Matthew
Rework the tx path to use the consumer and producer positions to work out the number of slots available, and to put packets on the ring until fewer than DWXE_NTXSEGS slots are left, making dwxe_start() and dwxe_txeof() work independently. While here, only write to DWXE_TX_CTL1 once per call to dwxe_start() rather than once per packet. Adjust the rx interrupt path to check the number of slots in use and return slots once per interrupt. Add interrupt and ifq barriers before taking the interface down. With all of this done, we can mark dwxe(4) mpsafe. tested on arm64 (a64 sopine) by mlarkin@ and armv7 (h2+) by me ok dlg@

The "label" property is obsolete and "function" should be used, but devices like the Raspberry Pi 4b still use it. Detect LEDs on such machines: -gpioleds0 at mainbus0: no LEDs +gpioleds0 at mainbus0: "led0", "led1" OK patrick

2021-11-05Newer i.MX device trees retriee the USB phy using the more generic propertyPatrick Wildt
name "phys". To handle those, make sure that we look it up and in case it's not there fall back to "fsl,usbphy". ok kettenis@
2021-10-31Extend the SPI bus API a bit. The config structure gets an sc_cs_delayMark Kettenis
member to allow us to specify a delay between assert the CS# signal and starting the clock. And the transfer function gains a flags argument, which can be used to specify a new SPI_KEEP_CS flag to keep CS# asserted after the transfer. This allows us to do another transfer immediately afterwards without de-asserting CS# which is necessary for sending commands to the upcoming Apple M1 keyboard/touchpad driver. ok patrick@

2021-10-10Apparently it is possible for firmware to indicate that SMCCC_VERSION isMark Kettenis
implemented but have that call return NOT_SUPPORTED. Makes no sense, but the SMCCC standard documents this and tells us to treat this as v1.0. Change the code accordingly. Turn a few checks that should always be true into KASSERTs to keep the control flow simple. ok patrick@
2021-10-04Allegedly a "Marvell Armada 3700 Functional Errata, Guidelines, andMark Kettenis
Restrictions" document exists that discusses an errata #251 in section "3.12 PCIe Completion Timeout" and suggests that setting the DIS_ORD_CHK flag in the Debug Mux Control register is necessary as a workaround: https://lore.kernel.org/linux-pci/20210624222621.4776-6-pali@kernel.org This workaround is still being discussed by the Linux developers, but it does fix an issue I am seeing with athn(4), where an external abort happens under load. So apply this workaround since its potential side effects seem to be significantly less severe than provoking an external abort that hangs the machine. ok patrick@

2021-08-02rkpwm(4) device tree bindings were updated to not have clock names anymore,Patrick Wildt
so simply look up the first clock instead of looking for a specific one by name. Allows rkpwm(4) to find the clock when using a recent device tree. From Tomasz Bielecki ok kettenis@
2021-07-29Change driver class from DV_DULL to DV_IFNET, so that it can be recognizedPatrick Wildt

2021-07-28The clocks for the Rockchip Ethernet controller need to be enabled muchPatrick Wildt
earlier. So far we haven't noticed this, as we had the assumption that all clocks are enabled anyway. On the NanoPi R4S this does not seem to be the case, so we need to bring the clock enable code closer to the other bringup code. ok kettenis@
2021-07-28On some RK3399 boards the firmware disables some of the clocks. AllowPatrick Wildt
some of those clocks to be enabled. Noticed on the NanoPi R4S, where the Ethernet controller clocks were surprisingly turned off. ok kettenis@

2021-07-07Rework TX handling to be more similar and comparable to our other modernPatrick Wildt
network controller drivers. This also removes a variable modified by both producer and consumer, making it a little bit more MP friendly. Fixes a panic reported by Matthieu Estrade.
2021-07-07When the list of free RX descriptors fills up completely, the consumedPatrick Wildt
and produced index are equal. The RX refill operation did not refill in that case, because it believed that this means there's nothing to do. In that case no RX buffers were allocated, and the RX descriptor ring went dry forever. Instead loop until we reach an empty freelist entry.
