Subject: [PATCH v4 0/2] Add the property to make backlight OCP level selectable

From: ChiYuan Huang <cy_huang@...htek.com>

This patch series is to add the backlight ocp level property parsing.

Since  v4
- Fix wrong macro usage, must be 'DIV_ROUND_UP', not 'roundup'

Since  v3
- Refine the description for backlight ocp property.
- Use the enum to list the supported value.

Since v2
- change the property name from the register style 'richtek,bled-ocp-cel' to
  'richtek,bled-ocp-microamp'.
- Use the clamp and roundup to get the ovp level selector.
