   4 Subject: [PATCH] regulator: qcom_spmi: add support for PMP8074 regulators
   5
   6 PMP8074 is a companion PMIC for the Qualcomm IPQ8074 WiSoC-s.
   7
   8 It features 5 HF-SMPS and 13 LDO regulators.
   9
  10 HF-SMPS regulators are Buck HFS430 regulators.
  11 L1, L2 and L3 are HT_N1200_ST subtype LDO regulators.
  12 L4 is HT_N300_ST subtype LDO regulator.
  13 L5 and L6 are HT_P600 subtype LDO regulators.
  14 L7, L11, L12 and L13 are HT_P150 subtype LDO regulators.
  15 L10 is HT_P50 subtype LDO regulator.
  16
  17 This commit adds support for all of the buck regulators and LDO-s except
  18 for L10 as I dont have documentation on its output voltage range.
  19
  20 S3 is the CPU cluster voltage supply, S4 supplies the UBI32 NPU cores
  21 and L11 is the SDIO/eMMC I/O voltage regulator required for high speeds.
