From 9038cd531382e94cc6d4daa9e81f70491030aa38 Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Wed, 13 May 2015 13:38:35 +0200 Subject: sandbox: dts: add sandbox_pmic.dtsi and include it to sandbox.dts and test.dts This commit adds dtsi file for Sandbox PMIC. It fully describes the PMIC by: - i2c emul node - with a default settings of 16 registers - 2x buck regulator nodes - 2x ldo regulator nodes The default register settings are set with preprocessor macros: - VAL2REG(min[uV/uA], step[uV/uA], val[uV/uA]) - VAL2OMREG(mode id) Both defined in file: - include/dt-bindings/pmic/sandbox_pmic.h The Voltage ranges of each regulator can be found in: - include/power/sandbox_pmic.h The new file is included into: - sandbox.dts - test.dts Signed-off-by: Przemyslaw Marczak Acked-by: Simon Glass Tested on sandbox: Tested-by: Simon Glass --- include/dt-bindings/pmic/sandbox_pmic.h | 35 +++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 include/dt-bindings/pmic/sandbox_pmic.h (limited to 'include/dt-bindings/pmic') diff --git a/include/dt-bindings/pmic/sandbox_pmic.h b/include/dt-bindings/pmic/sandbox_pmic.h new file mode 100644 index 0000000000..c3d839bf01 --- /dev/null +++ b/include/dt-bindings/pmic/sandbox_pmic.h @@ -0,0 +1,35 @@ +/* + * Copyright (C) 2015 Samsung Electronics + * Przemyslaw Marczak + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +#ifndef _DT_BINDINGS_SANDBOX_PMIC_H_ +#define _DT_BINDINGS_SANDBOX_PMIC_H_ + +/* + * Sandbox PMIC - prepare reset values + * To provide the default (reset) values as in the real hardware, + * the registers are set in i2c pmic emul driver's probe() method. + * The default values are defined as below. + */ + +/* Buck operation mode IDs */ +#define BUCK_OM_OFF 0 +#define BUCK_OM_ON 1 +#define BUCK_OM_PWM 2 +#define BUCK_OM_COUNT 3 + +/* Ldo operation mode IDs */ +#define LDO_OM_OFF 0 +#define LDO_OM_ON 1 +#define LDO_OM_SLEEP 2 +#define LDO_OM_STANDBY 3 +#define LDO_OM_COUNT 4 + +/* [Value uV/uA]/[Mode ID] to register */ +#define VAL2REG(min, step, val) (((val) - (min)) / (step)) +#define VAL2OMREG(x) (x) + +#endif -- cgit v1.2.3
