Merge tag 'regmap-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown: "This has been a busy release for the regmap-irq code, there's several new features been added, including an API cleanup for how we specify types that affected one existing driver (gpio-max77620): - Support for hardware that flags rising and falling edges on separate status bits from Bartosz Golaszewski. - Support for explicitly clearing interrupts before unmasking from Bartosz Golaszewski. - Support for level triggered IRQs from Matti Vaittinen" * tag 'regmap-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: irq: add an option to clear status registers on unmask regmap: regmap-irq/gpio-max77620: add level-irq support regmap: regmap-irq: Remove default irq type setting from core regmap: debugfs: convert to DEFINE_SHOW_ATTRIBUTE regmap: rbtree: convert to DEFINE_SHOW_ATTRIBUTE regmap: irq: handle HW using separate rising/falling edge interrupts regmap: add a new macro:REGMAP_IRQ_REG_LINE(_id, _reg_bits)
