5d1ebbda - phy: mapphone-mdm6600: Add USB PHY driver for MDM6600 on Droid 4

phy: mapphone-mdm6600: Add USB PHY driver for MDM6600 on Droid 4Let's add support for the GPIO controlled USB PHY on the MDM6600 modem.It is used on some Motorola Mapphone series of phones and tablets suchas Droid 4.The MDM6600 is hardwired to the first OHCI port in the Droid 4 case, andis controlled by several GPIOs. The USB PHY is integrated into the MDM6600device it seems. We know this as we get L3 errors from omap-usb-host iftrying to use the PHY before MDM6600 is configured.The GPIOs controlling MDM6600 are used to power device on and off, toconfigure the USB start-up mode (normal mode versus USB flashing), andthey also tell the state of the MDM6600 device.The two start-up mode GPIOs are dual-purposed and used for out of band(OOB) wake-up for USB and TS 27.010 serial mux. But we need to configurethe USB start-up mode first to get MDM6600 booted in the right mode tobe usable in the first place.Note that the Motorola Mapphone Linux kernel tree has a "radio-ctrl"driver for modems. But it really does not control the radio at all, itjust controls the modem power and start-up mode for USB. So I came tothe conclusion that we're better off having this done in the USB PHYdriver. For adding support for USB flashing mode, we can later on adda kernel module option for flash_mode=1 or something similar.Also note that currently there is no PM runtime support for the OHCIon omap variant SoCs. So for low(er) power idle states, currenty bothohci-platform and phy-mapphone-mdm6600 must be unloaded or unbound.For reference here is what I measured for total power consumption onan idle Droid 4 with and without USB related MDM6600 modules:idle lcd off phy-mapphone-mdm6600 ohci-platform153mW 284mW 344mWSo it seems that MDM6600 is currently not yet idling even with it'sradio turned off, but that's something that is beyond the control ofthis USB PHY driver. This patch does get us to the point where modemdata and GPS are usable with libqmi and ModemManager for example.Voice calls need more audio driver work.Cc: devicetree@vger.kernel.orgCc: Mark Rutland Cc: Marcel Partap Cc: Michael Scott Cc: Rob Herring Reviewed-by: Rob Herring Signed-off-by: Tony Lindgren Signed-off-by: Kishon Vijay Abraham I List of files: /linux-6.15/drivers/phy/motorola/Makefile

6d6ce40f - phy: cpcap-usb: Add CPCAP PMIC USB support

Tue, 23 May 2017 00:37:23 +0000

phy: cpcap-usb: Add CPCAP PMIC USB supportSome Motorola phones like droid 4 use a custom CPCAP PMIC that has amultiplexing USB PHY.This USB PHY can operate at least in four modes using pin multiplexingand 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 SoCThis 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. Thehost mode depends on the cpcap-charger driver for VBUS.VBUS and ID pin detection are done using cpcap-adc IIO ADCdriver.Cc: devicetree@vger.kernel.orgCc: Marcel Partap Cc: Michael Scott Acked-by: Rob Herring Tested-by: Sebastian Reichel Signed-off-by: Tony Lindgren Signed-off-by: Kishon Vijay Abraham I List of files: /linux-6.15/drivers/phy/motorola/Makefile
