[ Upstream commit 78bc671bd1501e2f6c571e063301a4fdc5db53b2 ]

Replace UFSHCD_QUIRK_BROKEN_64BIT_ADDRESS with
ufs_hba_variant_ops::set_dma_mask.  Update the Renesas driver
accordingly.  This patch enables supporting other configurations than
32-bit or 64-bit DMA addresses, e.g. 36-bit DMA addresses.

commit 7f45ed5f0cd5ccbbec79adc6c48a67d6a85fba56 upstream.

When the power mode change is successful but the power mode hasn't
actually changed, the post notification was missed.  Similar to the
approach with hibernate/clock scale/hce enable, having pre/post
notifications in the same function will make it easier to maintain.

Additionally, supplement the description of power parameters for the
pwr_change_notify callback.

[ Upstream commit 0c60eb0cc320fffbb8b10329d276af14f6f5e6bf ]

If the user sets use_mcq_mode to 0, the host will try to activate the LSDB
mode unconditionally even when the LSDBS of device HCI cap is 1. This makes
commands time out and causes device probing to fail.

To prevent that problem, check the LSDBS cap when MCQ is not supported.

The MCQ_OPR_OFFSET_n macro takes 'hba' in the caller context without
receiving 'hba' instance as an argument.  To prevent potential bugs in
future use cases, add an argument 'hba'.

Bart Van Assche <bvanassche@acm.org> says:

Hi Martin,

This patch includes the following changes, none of which should change the
functionality of the UFS host controller driver:
- Improve the kernel-doc headers further.
- Fix multiple W=2 compiler warnings.
- Simplify ufshcd_abort_all().
- Simplify the code for creating and parsing UFS Transport Protocol (UTP)
  headers.

Please consider this patch series for the next merge window.

Thanks,

Bart.

Make the code that parses UTP transfer request headers easier to read by
using u8 instead of __be32 where appropriate.

Remove the 'response' member variable because no code reads its value.
Additionally, move the ufs_query_req and ufs_query_res data structure
definitions into include/ufs/ufshcd.h because these data structures are
related to the UFS host controller driver.
