* usb: ulpi: Fix compile warning in read/write on 64-bit machines.Mateusz Kulikowski2016-04-01-2/+3
| | | | | | | | | | | | | | | | | | | ulpi_read and ulpi_write are used to read/write registers via ULPI bus. Code generates compilation warnings on 64-bit machines where pointer is cast to u32. This patch drops all but last 8 bits of register address. It is possible, because addresses on ULPI bus are 6- or 8-bit. It is not possible (according to ULPI 1.1 spec) to have more than 8-bit addressing. This patch should not cause regressions as all calls to ulpi_read/write use either structure pointer (@ address 0) or integer offsets cast to pointer - addresses requested are way below 8-bit range.

* usb: omap: ulpi: fix ulpi transceiver accessMichael Trimarchi2013-07-02-33/+9
| | | | | | | | | | | | | | | | | | | | | | This patch fix the omap access to the transceiver configuration registers using the ulpi bus. As reported by the documentation the bit31 is used only to check if the transaction is done or still running and the reading and writing operation have different offset and have different values. What we need to do at the end of a transaction is leave the bus in done state. Anyway an error using the ulpi omap register is not recoverable so any error give out the usage of this interface. Tested on a custom OMAP5430 board with a TUSB1210 ULPI PHY on USBB1.

* usb: ulpi: Add omap-ulpi-view port supportGovindraj.R2012-02-12-0/+106
| | | | | | | | | | | | | | | | | | | Based on discussion from this thread [1]. Adding omap-view port that helps us in using the generic ulpi framework for any ulpi phy ops using the INSNREG05_ULPI viewport reg available on omap platform. Currently ehci ports are available on omap3/4 platforms so enable the same for beagle and panda, patch is tested on the same boards. Thanks to Igor Grinberg <grinberg@compulab.co.il> for reviewing the omap-ehci patches and suggesting this approach.
