  gpiolib: Mark da9052 driver broken
  mfd: Declare da9052_regmap_config for the bus drivers
  MFD: DA9052/53 MFD core module add SPI support v2
  MFD: DA9052/53 MFD core module
  regmap: Add irq_base accessor to regmap_irq
  regmap: Allow drivers to reinitialise the register cache at runtime
  regmap: Add trace event for successful cache reads
  regmap: Allow regmap_update_bits() users to detect changes
  regmap: Report if we actually handled an interrupt in regmap-irq
  regmap: Fix rbtreee build when not using debugfs
  regmap: Provide debugfs dump of the rbtree cache data
  regmap: Do debugfs init before cache init
  regmap: Suppress noop writes in regmap_update_bits()
  regmap: Remove indexed cache type
  regmap: Drop check whether a register is readable in regcache_read
  regmap: Properly round cache_word_size
