An additional patch add also debug informations, displayed in case
of errors.
Alain Volmat (5):

The digital filter related computation are present in the driver
however the programming of the filter within the IP is missing.
The maximum value for the DNF is wrong and should be 15 instead of 16.

With the introduction of new flexgen compatible within the clk-flexgen
driver, remove the clock-output-names entry from the flexgen nodes
and set the new proper compatible corresponding.

The clkgen-pll driver now embed the clock names (assuming the
right compatible is used). Remove all clock-output-names property

Hello,
it turns out that some CLK_IS_CRITICAL are missing in the patches I sent.
(especially for the stih418).
I will send a v2 soon.

v2
Add support for the SMBus-Alert protocol to the STM32F7 that has
dedicated control and status logic.
If SMBus-Alert is used, the SMBALERT# pin must be configured as alternate
function for I2C Alert.

Once all DT will have been updated, the legacy mode could be removed
from the drivers.
This will also allow, once all STi DT will be corrected, to remove the
of_clk_detect_critical API from clk core code since STi clock drivers
are the only drivers using this API.

Once DTs will be fixed, the method relying on DT clock-output-names
will be removed from this driver as well as old compatibles.
