2019-10-23net: phy: broadcom: add 1000Base-X support for BCM54616STao Ren1-4/+53
The BCM54616S PHY cannot work properly in RGMII->1000Base-X mode, mainly because genphy functions are designed for copper links, and 1000Base-X (clause 37) auto negotiation needs to be handled differently. This patch enables 1000Base-X support for BCM54616S by customizing 3 driver callbacks, and it's verified to be working on Facebook CMM BMC platform (RGMII->1000Base-KX): - probe: probe callback detects PHY's operation mode based on INTERF_SEL[1:0] pins and 1000X/100FX selection bit in SerDES 100-FX Control register. - config_aneg: calls genphy_c37_config_aneg when the PHY is running in 1000Base-X mode; otherwise, genphy_config_aneg will be called. - read_status: calls genphy_c37_read_status when the PHY is running in 1000Base-X mode; otherwise, genphy_read_status will be called. Note: BCM54616S PHY can also be configured in RGMII->100Base-FX mode, and 100Base-FX support is not available as of now.

2019-10-18net: phy: avoid NPE if read_page/write_page callbacks are not availableHeiner Kallweit1-0/+6
Currently there's a bug in the module subsystem [0] preventing load of the PHY driver module on certain systems (as one symptom). This results in a NPE on such systems for the following reason: Instead of the correct PHY driver the genphy driver is loaded that doesn't implement the read_page/write_page callbacks. Every call to phy_read_paged() et al will result in a NPE therefore. In parallel to fixing the root cause we should make sure that this one and maybe similar issues in other subsystems don't result in a NPE in phylib. So let's check for the callbacks before using them and warn once if they are not available.

The KSZ8051 PHY and the KSZ8794/KSZ8795/KSZ8765 switch share exactly the same PHY ID. Since KSZ8051 is higher in the ksphy_driver[] list of PHYs in the micrel PHY driver, it is used even with the KSZ87xx switch. This is wrong, since the KSZ8051 configures registers of the PHY which are not present on the simplified KSZ87xx switch PHYs and misconfigures other registers of the KSZ87xx switch PHYs. Fortunatelly, it is possible to tell apart the KSZ8051 PHY from the KSZ87xx switch by checking the Basic Status register Bit 0, which is read-only and indicates presence of the Extended Capability Registers. The KSZ8051 PHY has those registers while the KSZ87xx switch does not. This patch implements simple check for the presence of this bit for both the KSZ8051 PHY and KSZ87xx switch, to let both use the correct PHY driver instance.

2019-10-16net: phy: Fix "link partner" information disappear issueYonglong Liu3-4/+12
Some drivers just call phy_ethtool_ksettings_set() to set the links, for those phy drivers that use genphy_read_status(), if autoneg is on, and the link is up, than execute "ethtool -s ethx autoneg on" will cause "link partner" information disappear. The call trace is phy_ethtool_ksettings_set()->phy_start_aneg() ->linkmode_zero(phydev->lp_advertising)->genphy_read_status(), the link didn't change, so genphy_read_status() just return, and phydev->lp_advertising is zero now.

This register reflects the actual mode that the PHY has resolved depending on either the advertisements of autoneg is enabled, or the forced mode if autoneg is disabled.

git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds Pull LED updates from Jacek Anaszewski: "In this cycle we've finally managed to contribute the patch set sorting out LED naming issues. Besides that there are many changes scattered among various LED class drivers and triggers. LED naming related improvements: - add new 'function' and 'color' fwnode properties and deprecate 'label' property which has been frequently abused for conveying vendor specific names that have been available in sysfs anyway - introduce a set of standard LED_FUNCTION* definitions - introduce a set of standard LED_COLOR_ID* definitions - add a new {devm_}led_classdev_register_ext() API with the capability of automatic LED name composition basing on the properties available in the passed fwnode; the function is backwards compatible in a sense that it uses 'label' data, if present in the fwnode, for creating LED name - add tools/leds/get_led_device_info.sh script for retrieving LED vendor, product and bus names, if applicable; it also performs basic validation of an LED name - update following drivers and their DT bindings to use the new LED registration API: - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114, leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt Other LED class improvements: - replace {devm_}led_classdev_register() macros with inlines - allow to call led_classdev_unregister() unconditionally - switch to use fwnode instead of be stuck with OF one LED triggers improvements: - led-triggers: - fix dereferencing of null pointer - fix a memory leak bug - ledtrig-gpio: - GPIO 0 is valid Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer, more complete driver exists, based on a generic driver for the AMD SOCs gpio-controller, supporting LEDs as well other devices: - drop profile field from priv data - drop iosize field from priv data - drop enum_apu_led_platform_types - drop superseeded apu2/3 led support - add pr_fmt prefix for better log output - fix error message on probing failure Other misc fixes and improvements to existing LED class drivers: - leds-ns2, leds-max77650: - add of_node_put() before return - leds-pwm, leds-is31fl32xx: - use struct_size() helper - leds-lm3697, leds-lm36274, leds-lm3532: - switch to use fwnode_property_count_uXX() - leds-lm3532: - fix brightness control for i2c mode - change the define for the fs current register - fixes for the driver for stability - add full scale current configuration - dt: Add property for full scale current. - avoid potentially unpaired regulator calls - move static keyword to the front of declarations - fix optional led-max-microamp prop error handling - leds-max77650: - add of_node_put() before return - add MODULE_ALIAS() - Switch to fwnode property API - leds-as3645a: - fix misuse of strlcpy - leds-netxbig: - add of_node_put() in netxbig_leds_get_of_pdata() - remove legacy board-file support - leds-is31fl319x: - simplify getting the adapter of a client - leds-ti-lmu-common: - fix coccinelle issue - move static keyword to the front of declaration - leds-syscon: - use resource managed variant of device register - leds-ktd2692: - fix a typo in the name of a constant - leds-lp5562: - allow firmware files up to the maximum length - leds-an30259a: - fix typo - leds-pca953x: - include the right header" * tag 'leds-for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds: (72 commits) leds: lm3532: Fix optional led-max-microamp prop error handling led: triggers: Fix dereferencing of null pointer leds: ti-lmu-common: Move static keyword to the front of declaration leds: lm3532: Move static keyword to the front of declarations leds: trigger: gpio: GPIO 0 is valid leds: pwm: Use struct_size() helper leds: is31fl32xx: Use struct_size() helper leds: ti-lmu-common: Fix coccinelle issue in TI LMU leds: lm3532: Avoid potentially unpaired regulator calls leds: syscon: Use resource managed variant of device register leds: Replace {devm_}led_classdev_register() macros with inlines leds: Allow to call led_classdev_unregister() unconditionally leds: lm3532: Add full scale current configuration dt: lm3532: Add property for full scale current. leds: lm3532: Fixes for the driver for stability leds: lm3532: Change the define for the fs current register leds: lm3532: Fix brightness control for i2c mode leds: Switch to use fwnode instead of be stuck with OF one leds: max77650: Switch to fwnode property API led: triggers: Fix a memory leak bug ...
2019-09-16net: phy: adin: implement Energy Detect Powerdown mode via phy-tunableAlexandru Ardelean1-0/+61
This driver becomes the first user of the kernel's `ETHTOOL_PHY_EDPD` phy-tunable feature. EDPD is also enabled by default on PHY config_init, but can be disabled via the phy-tunable control. When enabling EDPD, it's also a good idea (for the ADIN PHYs) to enable TX periodic pulses, so that in case the other PHY is also on EDPD mode, there is no lock-up situation where both sides are waiting for the other to transmit. Via the phy-tunable control, TX pulses can be disabled if specifying 0 `tx-interval` via ethtool. The ADIN PHY supports only fixed 1 second intervals; they cannot be configured. That is why the acceptable values are 1, ETHTOOL_PHY_EDPD_DFLT_TX_MSECS and ETHTOOL_PHY_EDPD_NO_TX (which disables TX pulses).

2019-09-16net: mdio: switch to using gpiod_get_optional()Dmitry Torokhov1-13/+9
The MDIO device reset line is optional and now that gpiod_get_optional() returns proper value when GPIO support is compiled out, there is no reason to use fwnode_get_named_gpiod() that I plan to hide away. Let's switch to using more standard gpiod_get_optional() and gpiod_set_consumer_name() to keep the nice "PHY reset" label. Also there is no reason to only try to fetch the reset GPIO when we have OF node, gpiolib can fetch GPIO data from firmwares as well.

2019-09-06net: phy: Do not check Link status when loopback is enabledJose Abreu1-0/+6
While running stmmac selftests I found that in my 1G setup some tests were failling when running with PHY loopback enabled. It looks like when loopback is enabled the PHY will report that Link is down even though there is a valid connection. As in loopback mode the data will not be sent anywhere we can bypass the logic of checking if Link is valid thus saving unecessary reads.
