2018-10-10net: phy: ti: Add binding for the CLK_OUT pin muxingJanine Hagemann
The DP83867 has a muxing option for the CLK_OUT pin. It is possible to set CLK_OUT for different channels. Create a binding to select a specific clock for CLK_OUT pin. Based on commit 9708fb630d19 ("net: phy: dp83867: Add binding for the CLK_OUT pin muxing option") of mainline linux kernel.

2018-10-10net: phy: ti: Recover from "port mirroring" N/A MODE4Janine Hagemann
The DP83867 when not properly bootstrapped - especially with LED_0 pin - can enter N/A MODE4 for "port mirroring" feature. To provide normal operation of the PHY, one needs not only to explicitly disable the port mirroring feature, but as well stop some IC internal testing (which disables RGMII communication). To do that the STRAP_STS1 (0x006E) register must be read and RESERVED bit 11 examined. When it is set, the another RESERVED bit (11) at PHYCR (0x0010) register must be clear to disable testing mode and enable RGMII communication. Thorough explanation of the problem can be found at following e2e thread: "DP83867IR: Problem with RESERVED bits in PHY Control Register (PHYCR) - Linux driver" https://e2e.ti.com/support/interface/ethernet/f/903/p/571313/2096954#2096954 Based on commit ac6e058b75be ("net: phy: dp83867: Recover from "port mirroring" N/A MODE4") of mainline linux kernel.

2018-10-10net: phy: ti: Add lane swapping support in the DP83867 TI's PHY driverJanine Hagemann
This patch adds support for enabling or disabling the lane swapping (called "port mirroring" in PHY's CFG4 register) feature of the DP83867 TI's PHY device. One use case is when bootstrap configuration enables this feature (because of e.g. LED_0 wrong wiring) so then one needs to disable it in software (at u-boot/Linux). Based on commit fc6d39c39581 ("net: phy: dp83867: Add lane swapping support in the DP83867 TI's PHY driver") of mainline linux kernel.

2018-07-26net: phy: dp83867: add workaround for incorrect RX_CTRL pin strapMurali Karicheri
The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017, advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not supported (see note below Table 5 (4-Level Strap Pins)). It further advises that if a board has this pin strapped in mode 1 and mode 2, then bit[7] of Configuration Register 4 (address 0x0031) must be cleared to 0. This is to ensure proper operation of PHY. Since it is not possible to detect in software if RX_DV/RX_CTRL pin is incorrectly strapped, add a device-tree property to advertise this and allow corrective action in software.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-02-07net: phy: ti: Fix dp83867 RGMII_TXID interface pathPhil Edworthy
There is code that is specifically for RGMII_TXID interface, but this will never get used because the code checks that the RGMII interface is RGMII_ID to RGMII_RXID; RGMII_TXID is after this. To fix this and avoid similar problems in the future, use the phy_interface_is_rgmii helper function.
