Merge tag 'davinci-for-v5.6/soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into arm/late

DaVinci SoC updates for v5.6 include migrating DM365 SoC to use
drivers/clocksource based driver for timer. This leads to removal
of machine specific timer driver.

There are two patches adding missing fixed regulators for audio codecs
on DM365 and DM644x EVMs.

* tag 'davinci-for-v5.6/soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci:
  ARM: davinci: dm644x-evm: Add Fixed regulators needed for tlv320aic33
  ARM: davinci: dm365-evm: Add Fixed regulators needed for tlv320aic3101
  ARM: davinci: remove legacy timer support
  ARM: davinci: dm365: switch to using the clocksource driver
  clocksource: davinci: only enable clockevents once tim34 is initialized
