2020-06-22phy: atheros: ar8035: Fix clock output calculationFabio Estevam
The clock ouput frequency is calculated incorrectly for AR8035 due to wrong masking of priv->clk_25m_reg and priv->clk_25m_mask. This same issue has been already fixed in the kernel by: commit b1f4c209d84057b6d40b939b6e4404854271d797 Author: Oleksij Rempel <o.rempel@pengutronix.de> Date: Wed Apr 1 11:57:32 2020 +0200 net: phy: at803x: fix clock sink configuration on ATH8030 and ATH8035 The masks in priv->clk_25m_reg and priv->clk_25m_mask are one-bits-set for the values that comprise the fields, not zero-bits-set. This patch fixes the clock frequency configuration for ATH8030 and ATH8035 Atheros PHYs by removing the erroneous "~". To reproduce this bug, configure the PHY with the device tree binding "qca,clk-out-frequency" and remove the machine specific PHY fixups.

2020-06-12net: phy: Add support for TI PHY initDan Murphy
ti_phy_init function was allocated to the DP83867 PHY. This function name is to generic for a specific PHY. The function can be moved to a TI specific file that can register all TI PHYs that are defined in the defconfig. The ti_phy_init file will contain all TI PHYs initialization so that only phy_ti_init can be called from the framework. In addition to the above the config flag for the DP83867 needs to be changed in the Kconfig and dependent defconfig files. The config flag that was used for the DP83867 was also generic in nature so a more specific config flag for the DP83867 was created.

If bisecting shows that this commit breaks your board it probably depends on the clock output of your Atheros AR8035 PHY. Please have a look at doc/device-tree-bindings/net/phy/atheros.txt. You need to set "clk-out-frequency = <125000000>" because that value was the hardcoded value until this commit.

Add support for configuring the CLK_25M pin as well as the RGMII I/O voltage by the device tree. By default the AT803x PHYs outputs the 25MHz clock of the XTAL input. But this output can also be changed by software to other frequencies. This commit introduces a generic way to configure this output. Also the PHY supports different RGMII I/O voltages: 1.5V, 1.8V and 2.5V. An internal LDO is able to provide 1.5V (default) and 1.8V. The 2.5V option needs an external supply voltage.

2020-05-07phy: atheros: Make RGMII Tx delays actually configurable for AR8035Vladimir Oltean
Delete the extraneous write to debug reg 5 that enables Tx delay When the driver was originally introduced in commit "6027384a phylib: Add Atheros AR8035 GETH PHY support", the Tx delay was being unconditionally enabled. Then during "2ec4d10b phy: atheros: add support for RGMII_ID, RGMII_TXID and RGMII_RXID", the author did not notice that code for enabling Tx delay code was already. Therefore, the if condition for Tx delay has always been useless for this PHY since this commit introduced it. Prior to this patch, every AR8035 PHY in U-boot had Tx delay enabled. After this patch, only those who define the interface as RGMII_TXID or RGMII_ID will. This is to be expected, but will nonetheless break the setups of those who didn't know they rely on Tx delay implicitly.

2020-03-09net: phy: marvell: Unify 88E151x series phy_driverClemens Gruber
The PHY models of the Marvell 88E151x series are not reliably distinguishable by their uid / PHY identifiers. The 88E1510, 88E1512, 88E1514 and 88E1518 all have the same OUI and model number and bits 3:0 in the PHY Identifier 2 (Page 0, Reg 3) are described as HW revision number, but both 88E1510 and 88E1518 PHYs were observed with the same HW rev number (1). Before commit 83cfbeb0df9f ("net: phy: Fix mask so that we can identify Marvell 88E1518"), the 88E151x were detected because the HW revision bits were masked from the uid. After that change, 88E1510/12/18 were all detected as 88E1518 and the 88E1510 specific code was no longer run. I modified the mask to again ignore all four HW revision bits, removed the 88E1510 specific code (board-specific LED/INTn setup), which was not called since late 2016 anyway and renamed the config function and phy_driver struct to the better fitting 88e151x. The uid and mask bits 3:0 are now again the same as in the Linux kernel. Signed-off-by: Clemens Gruber <clemens.gruber@pqgruber.com>

2020-03-09phy: Add support for the NC-SI protocolSamuel Mendoza-Jonas
This introduces support for the NC-SI protocol, modelled as a phy driver for other ethernet drivers to consume. NC-SI (Network Controller Sideband Interface) is a protocol to manage a sideband connection to a proper network interface, for example a BMC (Baseboard Management Controller) sharing the NIC of the host system. Probing and configuration occurs by communicating with the "remote" NIC via NC-SI control frames (Ethernet header 0x88f8). This implementation is roughly based on the upstream Linux implementation[0], with a reduced feature set and an emphasis on getting a link up as fast as possible rather than probing the full possible topology of the bus. The current phy model relies on the network being "up", sending NC-SI command frames via net_send_packet() and receiving them from the net_loop() loop (added in a following patch). The ncsi-pkt.h header[1] is copied from the Linux kernel for consistent field definitions.
