This allows secondary master to transmit DEFSLVS command properly. Main changes between v4 and v5: - Change in defslvs to use addr and lvr from i2c_dev_desc structure - Change in CDNS and DW drivers to use addr and lvr from i2c_dev_desc structure Signed-off-by: Przemyslaw Gaj <pgaj@cadence.com> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> 2019-08-11T08:45:52+00:00 Andy Shevchenko andriy.shevchenko@linux.intel.com 2019-07-25T20:51:45+00:00 urn:sha1:fd3f8f3118c66c492c5fe05568569d26db258fbd This simplifies and standardizes slot manipulation code by using for_each_set_bit() library function.

When I2C device with 10 bit address is defined in DT, I3C master registration fails. Address space for I2C devices has been reduced and ->i2c_funcs() hook has been removed. Because this patch series dropped support for 10 bit I2C devices, support is also dropped in Cadence I3C master driver and Synopsys DesignWare I3C master driver.

The correct way is to clear the DEV_CTRL_ENABLE bit. Fix this by clearing this bit.
