Hi,
This patch set improves the slow clock controller driver.
The first patch simply moves some code around to avoid having extern functions declared.
The second patch adds support for the SCKC found on sama5d4 and later. It is notably missing the OSC32EN bit. The third and fourth patches make use of this new driver (DT ABI is not broken \o/)
Finally, there is an optimization. Trying to find wether the slow oscillator is already stable to avoid waiting 1.2s twice in the boot process.
Changes in v2: - Fixed a typo pointed by Boris
