2017-08-30phy: add the mvebu cp110 comphy driverAntoine Tenart3-0/+656
On the CP110 unit, which can be found on various Marvell platforms such as the 7k and 8k (currently), a comphy (common PHYs) hardware block can be found. This block provides a number of PHYs which can be used in various modes by other controllers (network, SATA ...). These common PHYs must be configured for the controllers using them to work correctly either at boot time, or when the system runs to switch the mode used. This patch adds a driver for this comphy hardware block, providing callbacks for the its PHYs so that consumers can configure the modes used. As of this commit, two modes are supported by the comphy driver: sgmii and 10gkr.

git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next Chanwoo writes: Update extcon for 4.14 Detailed description for this pull request: 1. Add new 'extcon-usbc-cros-ec.c' driver - ChromeOS Embedded Controller extcon driver supports the detection of the Display Port (EXTCON_DISP_DP) through USB C-type and contol it. 2. Update extcon core - Modify the description for both functions and structures in order to improve the readability and give the more correct guide about the role of functions because there are different explanation even if the same arguments. - Keep the indentation with tab instead of space - Remove the following deprecated extcon API. The deprecated API are exchanged on all of linux tree. : extcon_get_cable_state_() -> extcon_get_state() : extcon_set_cable_state_() -> extcon_set_state_sync() 3. Include the two immutable branch as following: - ib-extcon-mfd-4.14 for the 'extcon-ubsc-cros-ec.c' driver because the patches of 'extcon-ubsc-cros-ec.c' touch the MFD directory. - ib-extcon-usb-phy-4.14 for removing the deprecated extcon API because the usb/phy driver usese the deprecated extcon API. So, this immutable branch alters the extcon API and then remove them from extcon. 4. Fix minor issue of extcon driver - Fix the MHL detection on extcon-max77693.c - Convert to using %pOF instead of full_name on extcon.c - Add 'const' kerywod for acpi_device_id on extcon-intel-int3496.c

2017-08-22phy: sun4i-usb: Support secondary clock for HSIC PHYChen-Yu Tsai1-0/+21
On the Allwinner A83T SoC, the last USB PHY is an HSIC PHY. It requires two clocks instead of one. On all Allwinner SoCs that share the common USB PHY design supported by the phy-sun4i-usb driver, the first PHY is always tied to OTG, and there is at most one HSIC PHY, typically the last. In this patch we take advantage of these known constraints and store an index in the compatible-string-related config structure describing which PHY is HSIC, needing the extra hsic_12M clock.

2017-06-16phy: bcm-ns-usb3: enable MDIO in the platform specific codeRafał Miłecki1-12/+6
When we finally start using MDIO layer then bus initialization will be handled in a separated driver. It means our code handling this has to be used for the platform driver only. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2017-06-16phy: bcm-ns-usb3: use pointer for PHY writing functionRafał Miłecki1-42/+56
Our current writing function accesses PHY directly bypassing MDIO layer. The aim is to extend this module to also behave as MDIO driver. This will require using different writing function which can be handled cleanly by having an extra pointer like this.

2017-06-16phy: bcm-ns-usb3: always wait for idle after writing to the PHY regRafał Miłecki1-10/+1
Move MDIO specific code to the writing helper function. This makes init code a bit more generic and doesn't require it to track what happens after every write. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

This is driver for USB DRD PHY used in Broadcom's Northstar2 SoC. The phy can be configured to be in Device mode or Host mode based on the type of cable connected to the port. The driver registers to extcon framework to get appropriate connect events for Host/Device cables connect/disconnect states based on VBUS and ID interrupts.

At the current rockchip-inno-usb2 phy driver framework, it can only support usb2-phy which comprises with one otg-port and one host-port. However, some Rockchip SoCs' (e.g RK3228, RK3229) usb2-phy comprises with two host-ports, so we use index of otg id for one host-port configuration, and make it work the same as otg-port host mode.

2017-06-06phy: rockchip-inno-usb2: increase otg sm work first schedule timeWilliam Wu1-1/+1
In rockchip-inno-usb2 phy driver, we use otg_sm_work to dynamically manage power consumption for phy otg-port. If the otg-port works as peripheral mode and does not communicate with usb host, we will suspend phy. But once suspend phy, the phy no longer has any internal clock running, include the utmi_clk which supplied for usb controller. So if we suspend phy before usb controller init, it will cause usb controller fail to initialize. Specifically, without this patch, the observed order is: 1. unplug usb cable 2. start system, do dwc2 controller probe 3. dwc2_lowlevel_hw_enable() - phy_init() - rockchip_usb2phy_init() - schedule otg_sm_work after 2s put phy in suspend, and close utmi_clk 4. dwc2_hsotg_udc_start() - fail to initialize the usb core Generally, dwc2_hsotg_udc_start() can be called within 5s after start system on Rockchip platform, so we increase the the first schedule delay time to 6s for otg_sm_work afer usb controller calls phy_init(), this can make sure that the usb controller completes initialization before phy enter suspend.

2017-06-06phy: cpcap-usb: Add CPCAP PMIC USB supportTony Lindgren5-0/+692
Some Motorola phones like droid 4 use a custom CPCAP PMIC that has a multiplexing USB PHY. This USB PHY can operate at least in four modes using pin multiplexing and two control GPIOS: - Pass through companion PHY for the SoC USB PHY - ULPI PHY for the SoC - Pass through USB for the modem - UART debug console for the SoC This patch adds support for droid 4 USB PHY and debug UART modes, support for other modes can be added later on as needed. Both peripheral and host mode are working for the USB. The host mode depends on the cpcap-charger driver for VBUS. VBUS and ID pin detection are done using cpcap-adc IIO ADC driver.
