This patch series improves the power up behavior by allowing MHI host driver to
set BHI and/or BHIe offsets early on in the preparation phase and fail pre-power
up if offsets are not found or not within a limited MMIO region. This also
allows MHI host to clean up the offsets in the unprepare after power down phase.

Going forward, controllers will be required to specify a reg_len field which
will be used to check whether the BHI/BHIe offsets are in range or not.

This series has been tested on X86_64 architecture with the PCI generic driver
as controller and an SDX55 device.

v4:
-Added reviewed-by tags
-Updated range check patch to include BHI/e offsets in the error message

v3:
-Added reviewed-by tags
-Updated order of reg_len in mhi_controller structure documentation

v2:
-Added reviewed-by tags
-Moved reg_len entry in mhi_controller structure to allow for a packed struct

Bhaumik Bhatt (6):
  bus: mhi: core: Set BHI/BHIe offsets on power up preparation
  bus: mhi: core: Set BHI and BHIe pointers to NULL in clean-up
  bus: mhi: Add MMIO region length to controller structure
  ath11k: set register access length for MHI driver
  bus: mhi: pci_generic: Set register access length for MHI driver
  bus: mhi: core: Add range checks for BHI and BHIe
