[PATCH v2] dt-bindings: mfd: rk808: Convert bindings to yaml

Chris Morgan macroalpha82 at gmail.com
Thu Sep 16 13:19:47 PDT 2021


From: Chris Morgan <macromorgan at hotmail.com>

Convert the rk808 bindings into yaml format. Please note that currently
there are a few errors that appear when performing a make dtbs_check.
However, after looking at the errors it appears in most cases it occurs
on device trees which are not following the current rk808.txt document
today. For example for the rk808 there are multiple errors regarding
vcc13-supply, vcc14-supply, and vddio-supply; however these supplies
are not listed in the current driver or cared for in any way.

For the moment the rk817 is the only MFD that will support a battery.
I believe the rk818 also supports a batter but I do not have one to
test or write the code for. When it is supported we can split off
the battery to its own document. Note that the battery is being added
in a separate commit series.

Changes from V1:

 - Removed generic descriptions.
 - Added maxItems to clock-output-names. Max items is 2 per the driver.
 - Added unevaluatedProperties as false to regulators.
 - Correct i2c node.
 - Added note about the battery.

-Regulators: All the regulators of RK8XX to be instantiated shall be
-listed in a child node named 'regulators'. Each regulator is represented
-by a child node of the 'regulators' node.
-
-	regulator-name {
-		/* standard regulator bindings here */
-	};
-
-Following regulators of the RK805 PMIC regulators are supported. Note that
-the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
-number as described in RK805 datasheet.
-
-	- DCDC_REGn
-		- valid values for n are 1 to 4.
-	- LDO_REGn
-		- valid values for n are 1 to 3
-
-Following regulators of the RK808 PMIC block are supported. Note that
-the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
-number as described in RK808 datasheet.
-
-	- DCDC_REGn
-		- valid values for n are 1 to 4.
-	- LDO_REGn
-		- valid values for n are 1 to 8.

-
-It is necessary to configure three pins for both the RK809 and RK817, the three
-pins are "gpio_ts" "gpio_gt" "gpio_slp".
-	The gpio_gt and gpio_ts pins support the gpio function.
-	The gpio_slp pin is for controlling the pmic states, as below:
-		- reset
-		- power down
-		- sleep
-
-Standard regulator bindings are used inside regulator subnodes. Check
-  Documentation/devicetree/bindings/regulator/regulator.txt
