2021-08-03ARM: dts: am4372: Add PRUSS MDIO controller nodeAndrew F. Davis1-0/+4
The PRU-ICSS1 instance on AM437x SoCs has a MDIO sub-module that can be used to control external PHYs associated with the Industrial Ethernet peripherals within the PRUSS. The MDIO module used within this PRU-ICSS is an instance of the MDIO Controller used in TI Davinci SoCs. The same bus frequency of 1 MHz is chosen as the regular MDIO node. Note that there is no MDIO node added to the smaller PRU-ICSS0 instance as the MDIO pins are not pinned out. The node is added and enabled in the common am4372.dtsi file by default, and disabled in all the existing AM437x board dts files. This node needs pinctrl lines, and so should be enabled only on boards where they are actually wired and pinned out for PRUSS Ethernet. Any new board dts file should disable these if they are not sure. Signed-off-by: Andrew F.

2020-09-25ARM: dts: am437x: switch to new cpsw switch drvGrygorii Strashko1-5/+8
The dual_mac mode has been preserved the same way between legacy and new driver, and one port devices works the same as 1 dual_mac port - it's safe to switch drivers. So, Switch all am437x boards to use new cpsw switch driver. Those boards have or 2 Ext. port wired and configured in dual_mac mode by default, or only 1 Ext. port.

2020-07-13Replace HTTP links with HTTPS ones: OMAP DEVICE TREE SUPPORTAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2020-05-08ARM: dts: am437x: fix networking on boards with ksz9031 phyGrygorii Strashko1-1/+1
Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY") the networking is broken on boards: am437x-gp-evm am437x-sk-evm am437x-idk-evm All above boards have phy-mode = "rgmii" and this is worked before, because KSZ9031 PHY started with default RGMII internal delays configuration (TX off, RX on 1.2 ns) and MAC provided TX delay. After above commit, the KSZ9031 PHY starts handling phy mode properly and disables RX delay, as result networking is become broken. Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous behavior.

2020-02-20ARM: dts: am437x-idk-evm: Fix incorrect OPP node namesSuman Anna1-2/+2
The commit 337c6c9a69af ("ARM: dts: am437x-idk-evm: Disable OPP50 for MPU") adjusts couple of OPP nodes defined in the common am4372.dtsi file, but used outdated node names. This results in these getting treated as new OPP nodes with missing properties. Fix this properly by using the correct node names as updated in commit b9cb2ba71848 ("ARM: dts: Use - instead of @ for DT OPP entries for TI SoCs").

2017-12-21ARM: dts: am437x-idk-evm: Disable OPP50 for MPUDave Gerlach1-0/+14
AM437x IDK has a TPS386000 supply voltage supervisor on the VDD_MPU rail set to trigger undervoltage condition at 0.96V. Because of this, OPP50, which is normally configured to 300MHz at 0.95V, must be disabled to avoid triggering the undervoltage condition. Also mark OPP100 as the suspend-opp as it is now our lowest OPP. Signed-off-by: Dave Gerlach <d-gerlach@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2017-05-26ARM: dts: omap: Add generic compatible string for I2C EEPROMJavier Martinez Canillas1-1/+1
The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.
