Subject: [PATCH v3 0/5] nvmem: qfprom: add Qualcomm SAR2130P support

Qualcomm SAR2130P is one of the platforms which require 4-byte reads
when accessing the QFPROM data. Fix several omission in the NVMEM core,
rework the QFPROM driver to use readl() instead of readb() and finally
add compatible string for the QFPROM as present on the Qualcomm
SAR2130P.

      nvmem: core: fix bit offsets of more than one byte
      nvmem: core: verify cell's raw_len
      nvmem: core: update raw_len if the bit reading is required
      nvmem: qfprom: switch to 4-byte aligned reads
      dt-bindings: nvmem: qcom,qfprom: Add SAR2130P compatible
