At the moment, MC34704 is the one that requires a short lenght. Maybe it is better to set 3 as default: #if defined(CONFIG_PMIC_FSL_MC34704) #define FSL_PMIC_I2C_LENGTH 1 #else #define FSL_PMIC_I2C_LENGTH 3 #endif > > #if defined(CONFIG_PMIC_SPI) > diff --git a/include/mc34704.h b/include/mc34704.h > new file mode 100644 > index 0000000..6611d54 > --- /dev/null > +++ b/include/mc34704.h > @@ -0,0 +1,49 @@ > +/* > + * (C) Copyright 2012 Freescale Semiconductor, Inc. > + * > + * This program is free software; you can redistribute it and/or > + * modify it under the terms of the GNU General Public License as > + * published by the Free Software Foundation; either version 2 of > + * the License, or (at your option) any later version. > + * > + */ > + > +#ifndef __MC34704_H__ > +#define __MC34704_H__ > + > +enum { > + MC34704_RESERVED0_REG = 0, /* 0x00 */ > + MC34704_GENERAL1_REG, /* 0x01 */ > + MC34704_GENERAL2_REG, /* 0x02 */ > + MC34704_GENERAL3_REG, /* 0x03 */ > + MC34704_RESERVED4_REG, /* 0x04 */ > + MC34704_VGSET2_REG, /* 0x05 */ > + MC34704_REG2SET1_REG, /* 0x06 */ > + MC34704_REG2SET2_REG, /* 0x07 */ > + MC34704_REG3SET1_REG, /* 0x08 */ > + MC34704_REG3SET2_REG, /* 0x09 */ > + MC34704_REG4SET1_REG, /* 0x0a */ > + MC34704_REG4SET2_REG, /* 0x0b */ > + MC34704_REG5SET1_REG, /* 0x0c */ > + MC34704_REG5SET2_REG, /* 0x0d */ > + MC34704_REG5SET3_REG, /* 0x0e */ > + MC34704_RESERVEDF_REG, /* 0x0f */ > + MC34704_RESERVED10_REG, /* 0x10 */ > + MC34704_RESERVED11_REG, /* 0x11 */ > + MC34704_RESERVED12_REG, /* 0x12 */ > + MC34704_FSW2SET_REG, /* 0x13 */ > + MC34704_RESERVED14_REG, /* 0x14 */ > + MC34704_REG8SET1_REG, /* 0x15 */ > + MC34704_REG8SET2_REG, /* 0x16 */ > + MC34704_REG8SET3_REG, /* 0x17 */ > + MC34704_FAULTS_REG, /* 0x18 */ > + MC34704_I2CSET1, /* 0x19 */ > + MC34704_NUM_OF_REGS, > +}; > + > +/* GENERAL2 register fields */ > +#define ONOFFE (1 << 0) > +#define ONOFFD (1 << 1) > +#define ALLOFF (1 << 4) > + > +#endif /* __MC34704_H__ */ > -- ===================================================================== DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: +49-8142-66989-53 Fax: +49-8142-66989-80 Email: sbabic at denx.de =====================================================================
