Convert devicetree bindings for the Broadcom BCM59056 PMU MFD from TXT to YAML format. This patch does not change any functionality; the bindings remain the same. The bindings have been split into two parts: the MFD binding and a separate binding for the regulator node, to simplify the addition of other models later (which have different regulators). Signed-off-by: Artur Weber <aweber.kernel@gmail.com> --- Changes in v4: - Made $ref use full schema path - Cleaned up example - Dropped regulator name list comment - Changed description of regulator binding to mention BCM59056 explicitly - Changed "Power Management IC" to "Power Management Unit" to match official Broadcom naming - Renamed mfd/brcm,bcm59056.yaml to mfd/brcm,bcm590xx.yaml Changes in v3: - Moved regulator node to separate binding - Removed quotes around compatibles/vbus property - Style fixes for example --- .../devicetree/bindings/mfd/brcm,bcm59056.txt | 39 ---------------- .../devicetree/bindings/mfd/brcm,bcm590xx.yaml | 54 ++++++++++++++++++++++ .../bindings/regulator/brcm,bcm59056.yaml | 51 ++++++++++++++++++++ 3 files changed, 105 insertions(+), 39 deletions(-)
