* i2c: drivers: Use generic definitions for bus frequenciesAndy Shevchenko2020-03-241-7/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we have generic definitions for bus frequencies, let's use them.

* i2c: busses: make use of i2c_8bit_addr_from_msgPeter Rosin2018-05-291-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Because it looks neater. For diolan, this allows factoring out some code that is now common between if and else. For eg20t, pch_i2c_writebytes is always called with a write in msgs->flags, and pch_i2c_readbytes with a read. For imx, i2c_imx_dma_write and i2c_imx_write are always called with a write in msgs->flags, and i2c_imx_read with a read. For qup, qup_i2c_write_tx_fifo_v1 is always called with a write in qup->msg->flags. For stu300, also restructure debug output for resends, since that code as a result is only handling debug output.

* i2c: remove unnecessary OOM messagesJingoo Han2014-06-021-1/+0
| | | | | | | | | | | | | | | The site-specific OOM messages are unnecessary, because they duplicate the MM subsystem generic OOM message. For example, k.alloc and v.alloc failures use dump_stack().

* i2c: i2c-diolan-u2c: different usb endpoints for DLN-2-U2CMartin Vogt2013-11-261-5/+11
| | | | | | | | | | | | | | The previous diolan adapter uses other out/in endpoints than the current DLN-2-U2C in compatibility mode. They changed from 0x2/0x84 to 0x3/0x83. This patch gets the endpoints from the usb interface, instead of hardcode them in the driver. This was tested on a current DLN-2-U2C board.

* USB: convert some miscellanies drivers to use module_usb_driver()Greg Kroah-Hartman2011-11-181-14/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This converts the remaining USB drivers in the kernel to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Added bonus is that it removes some unneeded kernel log messages about drivers loading and/or unloading.
