Cadence has designed a D-PHY that can be used by the, currently in tree, DSI bridge (DRM), CSI Transceiver and CSI Receiver (v4l2) drivers. Only the DSI driver has an ad-hoc driver for that phy at the moment, while the v4l2 drivers are completely missing any phy support. In order to make that phy support available to all these drivers, without having to duplicate that code three times, let's create a generic phy framework driver.

Add a driver to support COMPHY, a hardware block providing shared serdes PHYs on Marvell Armada 3700. This driver uses SMC calls and rely on having an up-to-date firmware. SATA, PCie and USB3 host mode have been tested successfully with an ESPRESSObin. (HS)SGMII mode cannot be tested with this platform. Evan worked on the original driver structure and Grzegorz on the SMC calls rework. The structure of this driver has been copied from Antoine Tenart work on CP110 COMPHY driver.

2019-02-07phy: mvebu-cp110-comphy: fix port check in ->xlate()Miquel Raynal1-2/+0
So far the PHY ->xlate() callback was checking if the port was "invalid" before continuing, meaning that the port has not been used yet. This check is not correct as there is no opposite call to ->xlate() once the PHY is released by the user and the port will remain "valid" after the first phy_get()/phy_put() calls. Hence, if this driver is built as a module, inserted, removed and inserted again, the PHY will appear busy and the second probe will fail. To fix this, just drop the faulty check and instead verify that the port number is valid (ie. in the possible range).

That property is no used in mainline and is not documented. The only board using that property is the rk33-99-evb-rev1 and -rev2 in the vendor kernel. The existence of a further -rev3 (which also looks way better cared for compared rev1+2) indicates that the older ones are probably some sort of preproduction models, where some wiring (on the soc or board) may have gone wrong. It is also not clear why this is a hardware-description or a DT property, so, as noboby seems to care of this just drop reading that property.

2019-01-16phy: ath79-usb: Fix the main reset name to match the DT bindingAlban Bedel1-1/+1
I submitted this driver several times before it got accepted. The first series hasn't been accepted but the DTS binding did made it. I then made a second series that added generic reset support to the PHY core, this in turn required a change to the DT binding. This second series seemed to have been ignored, so I did a third one without the change to the PHY core and the DT binding update, and this last attempt finally made it. But two months later the DT binding update from the second series has been integrated too. So now the driver doesn't match the binding and the only DTS using it.

Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses the PHY_MODE_SATA, but that enum had not yet been added. This caused a build failure for me, with today's linux.git. Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding in the Marvell Berlin SATA PHY driver. Fix the build by: 1) Renaming Marvell's defined value to a more scoped name, in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA. 2) Adding the missing enum, which was going to be added anyway as part of [1].

2019-01-12phy: fix build breakage: add PHY_MODE_SATAJohn Hubbard1-2/+3
Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses the PHY_MODE_SATA, but that enum had not yet been added. This caused a build failure for me, with today's linux.git. Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding in the Marvell Berlin SATA PHY driver. Fix the build by: 1) Renaming Marvell's defined value to a more scoped name, in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA. 2) Adding the missing enum, which was going to be added anyway as part of [1].

2018-12-12phy: qcom-qmp: Utilize fully-specified DT registersEvan Green1-13/+38
Utilize the newly fixed up DT bindings to get the tx2 and rx2 register regions for the second lane of dual-lane PHYs. Before this change, the driver was simply using lane one's register region and adding 0x400, which reached well beyond the DT-specified register allocation. This would have been a crash were it not for the page size on ARM64. Fix the driver not to rely on the magic of virtual memory by using the newly specified DT register regions for tx2 and rx2. In order to support existing device trees, this change also contains a fallback mode for when those new register regions don't exist, which reverts to the original behavior of overreaching and prints a complaint.

2018-12-12phy: Add configuration interfaceMaxime Ripard1-0/+64
The phy framework is only allowing to configure the power state of the PHY using the init and power_on hooks, and their power_off and exit counterparts. While it works for most, simple, PHYs supported so far, some more advanced PHYs need some configuration depending on runtime parameters. These PHYs have been supported by a number of means already, often by using ad-hoc drivers in their consumer drivers. That doesn't work too well however, when a consumer device needs to deal with multiple PHYs, or when multiple consumers need to deal with the same PHY (a DSI driver and a CSI driver for example). So we'll add a new interface, through two funtions, phy_validate and phy_configure. The first one will allow to check that a current configuration, for a given mode, is applicable. It will also allow the PHY driver to tune the settings given as parameters as it sees fit. phy_configure will actually apply that configuration in the phy itself.

2018-12-12phy: ti: introduce phy-gmii-sel driverGrygorii Strashko3-0/+360
TI am335x/am437x/dra7(am5)/dm814x CPSW3G Ethernet Subsystem supports two 10/100/1000 Ethernet ports with selectable G/MII, RMII, and RGMII interfaces. The interface mode is selected by configuring the MII mode selection register(s) (GMII_SEL) in the System Control Module chapter (SCM). GMII_SEL register(s) and bit fields placement in SCM are different between SoCs while fields meaning is the same. Historically CPSW external Port's interface mode selection configuration was introduced using custom API and driver cpsw-phy-sel.c. This leads to unnecessary driver, DT binding and custom API support effort. This patch introduces CPSW Port's PHY Interface Mode selection Driver (phy-gmii-sel) which implements standard Linux PHY interface and used as a replacement for TI's specific driver cpsw-phy-sel.c and corresponding custom API.

2018-12-12phy: mapphone-mdm6600: Improve phy related runtime PM callsTony Lindgren1-20/+51
I noticed that phy_pm_runtime_get_sync() and phy_pm_runtime_put() are not currently doing anything for phy-mapphone-mdm6600, only the sysfs interface for works for "auto" and "on". This is because of the shared GPIO pins between mdm6600 USB port and n_gsm port. We have not enabled runtime PM for the phy driver until after we've booted up mdm6600 properly to the USB mode. Otherwise phy_create() would have called pm_runtime_enable() and pm_runtime_no_callbacks() automatically on init. Let's fix this by registering the phy a bit later after we've powered up the mdm6600 USB port. And as the PM runtime support is only needed for the n_gsm mode and not for USB, we can allow the device to idle between phy_mdm6600_power_on() and phy_mdm6600_power_off(). Note that for suspend, runtime_pm is already disabled for the phy so we need to check for pm_runtime_enabled().

2018-12-12phy: cadence: Add driver for Sierra PHYAlan Douglas3-1/+404
Add a Sierra PHY driver with PCIe and USB support. The PHY has multiple lanes, which can be configured into groups, and a generic PHY device is created for each group. There are two resets controlling the overall PHY block, one to enable the APB interface for programming registers, and another to enable the PHY itself. Additionally there are resets for each PHY lane. The PHY can be configured in hardware to read register settings from ROM, or they can be written by the driver. The sequence of operation on startup is to enable the APB bus, write the PHY registers (if required) for each lane group, and then enable the PHY. Each group of lanes can then be individually controlled using the power_on()/ power_off() function for that generic PHY Signed-off-by: Alan Douglas <adouglas@cadence.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

2018-12-12phy: core: rework phy_set_mode to accept phy mode and submodeGrygorii Strashko15-19/+29
Currently the attempt to add support for Ethernet interface mode PHY (MII/GMII/RGMII) will lead to the necessity of extending enum phy_mode and duplicate there values from phy_interface_t enum (or introduce more PHY callbacks) [1]. Both approaches are ineffective and would lead to fast bloating of enum phy_mode or struct phy_ops in the process of adding more PHYs for different subsystems which will make them unmaintainable. As discussed in [1] the solution could be to introduce dual level PHYs mode configuration - PHY mode and PHY submode. The PHY mode will define generic PHY type (subsystem - PCIE/ETHERNET/USB_) while the PHY submode - subsystem specific interface mode. The last is usually already defined in corresponding subsystem headers (phy_interface_t for Ethernet, enum usb_device_speed for USB). This patch is cumulative change which refactors PHY framework code to support dual level PHYs mode configuration - PHY mode and PHY submode. It extends .set_mode() callback to support additional parameter "int submode" and converts all corresponding PHY drivers to support new .set_mode() callback declaration. The new extended PHY API int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode) is introduced to support dual level PHYs mode configuration and existing phy_set_mode() API is converted to macros, so PHY framework consumers do not need to be changed (~21 matches).
