Hi, > The current driver uses input clock source frequency to calculate > values for [SS|FS]_[HC|LC] registers. However, when booting ACPI, we do not > currently have a good way to provide the frequency information. > Instead, we can leverage the SSCN and FFCN ACPI methods, which can be used > to directly provide these values. So, the clock information should > no longer be required during probing. > > However, since clk can be invalid, additional checks must be done where > we are making use of it. > > Signed-off-by: Suravee Suthikulpanit <Suravee.Suthikulpanit@xxxxxxx> > --- > > Note: This has been tested on AMD Seattle RevB for both DT and ACPI. Tested on X-Gene hardware also. -Loc -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
