* i2c: xlp9xx: Fix module autoloadJavier Martinez Canillas2016-10-25
| | | | | | | | | | | If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro.

* i2c: xlp9xx: add ACPI support for Broadcom VulcanTanmay Jagdale2016-07-07
| | | | | | | | | | | | | Added ACPI support for the I2C controller present on Broadcom's Vulcan ARM64 processor. ACPI ID used by the controller is BRCM9007. Changed the xlp9xx_i2c_get_frequency() function to use device_property_read_u32() API so that the "clock-frequency" value can be read from _DSD in ACPI mode.
