     14    rpmh-regulator devices support PMIC regulator management via the Voltage
     15    Regulator Manager (VRM) and Oscillator Buffer (XOB) RPMh accelerators.
     16    The APPS processor communicates with these hardware blocks via a
     17    Resource State Coordinator (RSC) using command packets.  The VRM allows
     18    changing three parameters for a given regulator, enable state, output
     19    voltage, and operating mode.  The XOB allows changing only a single
     20    parameter for a given regulator, its enable state.  Despite its name,
     21    the XOB is capable of controlling the enable state of any PMIC peripheral.
     22    It is used for clock buffers, low-voltage switches, and LDO/SMPS regulators
     23    which have a fixed voltage and mode.
     24
     25    =======================
     26    Required Node Structure
     27    =======================
     28
     29    RPMh regulators must be described in two levels of device nodes.  The first
     30    level describes the PMIC containing the regulators and must reside within an
     31    RPMh device node.  The second level describes each regulator within the PMIC
     32    which is to be used on the board.  Each of these regulators maps to a single
     33    RPMh resource.
     34
     35    The names used for regulator nodes must match those supported by a given
     36    PMIC. Supported regulator node names are
     37      For PM6150, smps1 - smps5, ldo1 - ldo19
     38      For PM6150L, smps1 - smps8, ldo1 - ldo11, bob
     39      For PM6350, smps1 - smps5, ldo1 - ldo22
     40      For PM7325, smps1 - smps8, ldo1 - ldo19
     41      For PM8005, smps1 - smps4
     42      For PM8009, smps1 - smps2, ldo1 - ldo7
     43      For PM8150, smps1 - smps10, ldo1 - ldo18
     44      For PM8150L, smps1 - smps8, ldo1 - ldo11, bob, flash, rgb
     45      For PM8350, smps1 - smps12, ldo1 - ldo10
     46      For PM8350C, smps1 - smps10, ldo1 - ldo13, bob
     47      For PM8450, smps1 - smps6, ldo1 - ldo4
     48      For PM8998, smps1 - smps13, ldo1 - ldo28, lvs1 - lvs2
     49      For PMI8998, bob
     50      For PMR735A, smps1 - smps3, ldo1 - ldo7
     51      For PMX55, smps1 - smps7, ldo1 - ldo16
     52      For PMX65, smps1 - smps8, ldo1 - ldo21
