Add sama5d2 hlcdc backlight PWM support. This chip doesn't have to deal with an
errata, so it's a simple addition of the mfd compatible string.Signed-off-by: Nicolas Ferre

This platform driver has a OF device ID table but the OF module alias
information is not created so module autoloading won't work.This patch adds the missing MODULE_DEVICE_TABLE() for OF to export that
information so modules have the correct aliases built-in and autoloading
works correctly.A longer explanation by Javier Canillas can be found here:

sama5d4 SoC also has an errata on the HLCDC PWM. It is the same as the
sama5d3 that is forbidding the use of div1 prescaler.Signed-off-by: Nicolas Ferre

The slow and system clock should never return a rate of zero, but this
might happen if the clocks property defined in the DT is referencing the
wrong clocks.Prevent any division by zero from happening by testing the clk_freq
value before calling do_div().Signed-off-by: Boris Brezillon

at91sam9x5 has an errata forbidding the use of slow clk as a clk source and
sama5d3 SoCs has another errata forbidding the use of div1 prescaler.Take both of these erratas into account.

The HLCDC IP available in some Atmel SoCs (i.e. at91sam9x5, at91sam9n12
or sama5d3 families for instance) provides a PWM device.This driver add support for a PWM chip exposing a single PWM device (which
will most likely be used to drive a backlight device).Signed-off-by: Boris Brezillon
