Merge tag 'at91-fixes-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/at91/linux into arm/fixes
AT91 fixes for 6.0
It contains:
- fixes for self-refresh on SAMA7G5 while in AT91 power management modes:
one disabling a DDR PHY controller DLL which has been proved to be buggy
and can introduce glitches that can cause unexpected behavior; one
fixing the DDR PHY recalibration which cannot work for all possible
cases (due to hardware bug) while using backup and self-refresh AT91
power management mode;
- one defconfig fix to remove CONFIG_MICROCHIP_PIT64B from all AT91
defconfigs;
- multiple device tree fixes for regulators to avoid having some of them
enabled all the time and to describe min and max output ranges
according to board capabilities.
