* ARM: dts: ls1021a-tsn: update RGMII delays for sja1105 switchVladimir Oltean2021-11-211-0/+2
| | | | | | | | | | | | | | | | | | | In the new behavior, the sja1105 driver expects there to be explicit RGMII delays present on the fixed-link ports, otherwise it will complain that it falls back to legacy behavior, which is to apply RGMII delays incorrectly derived from the phy-mode string. In this case, the legacy behavior of the driver is to not apply delays in any direction (mostly because the SJA1105T can't do that, so this board uses PCB traces). To preserve that but also silence the driver, use explicit delays of 0 ns. The delay information from the phy-mode is ignored by new kernels (it's still RGMII as long as it's "rgmii*" something), and the explicit {rx,tx}-internal-delay-ps properties are ignored by old kernels, so the change works both ways.

* ARM: dts: ls1021a-tsn: use generic "jedec,spi-nor" compatible for flashLi Yang2021-10-151-1/+1
| | | | | | | | | | | We cannot list all the possible chips used in different board revisions, just use the generic "jedec,spi-nor" compatible instead. This also fixes dtbs_check error: ['jedec,spi-nor', 's25fl256s1', 's25fl512s'] is too long Signed-off-by: Li Yang <leoyang.li@nxp.com> Reviewed-by: Kuldeep Singh <kuldeep.singh@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

* ARM: dts: ls1021a-tsn: Use interrupts for the SGMII PHYsVladimir Oltean2019-12-091-0/+4
| | | | | | | | | | | | | | | | On the LS1021A-TSN board, the 2 Atheros AR8031 PHYs for eth0 and eth1 have interrupt lines connected to the shared IRQ2_B LS1021A pin. Switching to interrupts offloads the PHY library from the task of polling the MDIO status and AN registers (1, 4, 5) every second. Unfortunately, the BCM5464R quad PHY connected to the switch does not appear to have an interrupt line routed to the SoC.

* ARM: dts: Introduce the NXP LS1021A-TSN boardVladimir Oltean2019-06-131-0/+289
The LS1021A-TSN is a development board built by VVDN/Argonboards in partnership with NXP. It features the LS1021A SoC and the first-generation SJA1105T Ethernet switch for prototyping implementations of a subset of IEEE 802.1 TSN standards. It has two regular Ethernet ports and four switched, TSN-capable ports. It also features: - One Arduino header - One expansion header - Two USB 3.0 ports - One mini PCIe slot - One SATA interface - Accelerometer, gyroscope, temperature sensors Signed-off-by: Vladimir Oltean <olteanv@gmail.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
