2012-07-02usb: phy: fix return value check of usb_get_phyKishon Vijay Abraham I
usb_get_phy will return -ENODEV if it's not able to find the phy. Hence fixed all the callers of usb_get_phy to check for this error condition instead of relying on a non-zero value as success condition.

2012-06-25usb: otg: support for multiple transceivers by a single controllerKishon Vijay Abraham I
Add a linked list for keeping multiple PHY instances with different types so that we can have separate USB2 and USB3 PHYs on one single board. _get_phy_ has been changed so that the controller gets the transceiver by type. _remove_phy_ has been added to let the phy be removed from the phy list.

2012-06-25usb: otg: utils: rename function name in OTG utilsKishon Vijay Abraham I
_transceiver() in otg.c is replaced with _phy. usb_set_transceiver is replaced with usb_add_phy to make it similar to other usb standard function names like usb_add_hcd. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

The ISP1704/1707 chip can be put to full power down state by asserting the CHIP_SEL line. This patch enables platform or board specific hooks to put the device into power down mode in case not needed. This patch is a preparation for enabling this powering routine in n900 (rx-51) devices.

2010-11-18isp1704_charger: Detect HUB/Host chargersHeikki Krogerus
To avoid breaking high speed chirp handshaking with CDP chargers, no more then 500mA should be drawn. To make sure of this, utilizing current_max property. After the device has enumerated, it's safe to draw the maximum 1800mA as defined in the Battery Charging Specification. This can be also used with normal USB connection if the controller sends ENUMERATED notification with the milliamps as data. From now on the online property indicates VBUS, present property if there is a charger and current_max the milliamps possible to draw from VBUS.
