      ARM: dts: exynos: Mark LDO10 as always-on on Peach Pit/Pi Chromebooks · 5b0eeeaa
      Marek Szyprowski authored
      Commit aff138bf ("ARM: dts: exynos: Add TMU nodes regulator supply
      for Peach boards") assigned LDO10 to Exynos Thermal Measurement Unit,
      but it turned out that it supplies also some other critical parts and
      board freezes/crashes when it is turned off.
      
      The mentioned commit made Exynos TMU a consumer of that regulator and in
      typical case Exynos TMU driver keeps it enabled from early boot. However
      there are such configurations (example is multi_v7_defconfig), in which
      some of the regulators are compiled as modules and are not available
      from early boot. In such case it may happen that LDO10 is turned off by
      regulator core, because it has no consumers yet (in this case consumer
      drivers cannot get it, because the supply regulators for it are not yet
      available). This in turn causes the board to crash. This patch restores
      'always-on' property for the LDO10 regulator.
