Surely this could be a common property.

We have a standard properties for keycodes.

Sorry I'm not very clear about this. Could i move this to required
properties or remove the "mediatek" string here?

Could i write them like this way?

linux,keycodes = <KEY_POWER>, <KEY_VOLUMEDOWN>

+MediaTek MT6397/MT6323 PMIC Keys Device Driver

+There are two key functions provided by MT6397/MT6323 PMIC, pwrkey
+and homekey. The key functions are defined as the subnode of the function
+node provided by MT6397/MT6323 PMIC that is being defined as one kind
+of Muti-Function Device (MFD)
+
+For MT6397/MT6323 MFD bindings see:
+Documentation/devicetree/bindings/mfd/mt6397.txt
+
+Required properties:
+- compatible: "mediatek,mt6397-keys" or "mediatek,mt6323-keys"
+- mediatek,pwrkey-code: Keycode of pwrkey
+
+Optional Properties:
+- mediatek,homekey-code: Keycode of homekey
+- mediatek,long-press-mode: Long press key shutdown setting, 1 for
+	pwrkey only, 2 for pwrkey/homekey together, others for disabled.
+- mediatek,long-press-duration: Long press key shutdown duration setting,
+	0/1/2/3 for 8/11/14/5 seconds.

+Example:
