The driver currently supports two IP-core versions. It's DW APB SSI which
is older version of the controller with APB system bus interface, and DW
SSI controller with AHB bus interface. The later one is supposed to be a
new generation high-speed SSI. Even though both of these IP-cores have got
an almost identical registers space there are some differences. The driver
differentiates these distinctions by the DW_SPI_CAP_DWC_HSSI capability
flag. In addition to that each DW SSI IP-core is equipped with a Synopsys
Component version register, which encodes the IP-core release ID the has
been synthesized from. Seeing we are going to need the later one to
differentiate some controller peculiarities it would be better to have a
unified interface for both IP-core line and release versions instead of
using each of them separately.
Introduced here IP-core versioning interface consists of two parts:
1) IDs of the IP-core (virtual) and component versions.
2) a set of macro helpers to identify current IP-core and component
versions.
So the platform code is supposed to assign a proper IP-core version based
on it's platform -knowledge. The main driver initialization method reads
the IP-core release ID from the SSI component version register. That data
is used by the helpers to distinguish one IP-core release from another.
Thus the rest of the driver can use these macros to implement the
conditional code execution based on the specified IP-core and version IDs.
Collect the IP-core versions interface and the defined capabilities at the
top of the header file since they represent a common device description
data and so to immediately available for the driver hackers.

The driver has been using the offset/bitwise-shift-based approach for the
CSR fields R/W operations since it was merged into the kernel. It can be
simplified by using the macros defined in the linux/bitfield.h and
linux/bit.h header files like BIT(), GENMASK(), FIELD_PREP(), FIELD_GET(),
etc where it is required, for instance in the cached cr0 preparation
method. Thus in order to have the FIELD_*()-macros utilized we just need
to convert the macros with the CSR-fields offsets to the masks with the
corresponding registers fields definition. That's where the GENMASK() and
BIT() macros come in handy. After that the masks can be used in the
FIELD_*()-macros where it's appropriate.
We also need to convert the macros with the CRS-bit flags using the manual
bitwise shift operations (x << y) to using the BIT() macro. Thus we'll
have a more coherent set of the CSR-related macros.

Mostly due to a long driver history it's methods and macro names look a
bit messy. In particularly that concerns the code their prefixes. A
biggest part of the driver functions and macros have got the dw_spi/DW_SPI
prefixes. But there are some entities which have been just
"spi_/SPI_"-prefixed. Especially that concerns the CSR and their fields
macro definitions. It makes the code harder to comprehend since such
methods and macros can be easily confused with the global SPI-subsystem
exports. In this case the only possible way to more or less quickly
distinguish one naming space from another is either by context or by the
argument type, which most of the times isn't that easy anyway. In addition
to that a new DW SSI IP-core support has been added in the framework of
commit e539f435cb9c ("spi: dw: Add support for DesignWare DWC_ssi"), which
introduced a new set or macro-prefixes to describe CTRLR0-specific fields
and worsen the situation. Finally there are methods with
no DW SPI driver-reference prefix at all, that make the code reading even
harder. So in order to ease the driver hacking let's bring the code naming
to a common base:
1) Each method is supposed to have "dw_spi_" prefix so to be easily
distinguished from the kernel API, e.g. SPI-subsystem methods and macros.
(Exception is the local implementation of the readl/writel methods since
being just the regspace accessors.)
2) Each generically used macro should have DW_SPI_-prefix thus being
easily comprehended as the local driver definition.
3) DW APB SSI and DW SSI specific macros should have prefixes as DW_PSSI_
and DW_HSSI_ respectively so referring to the system buses they support
(APB and AHB similarly to the DT clocks naming like pclk, hclk).

The dw_ssi_type enumeration describes the SPI frame formats the controller
supports, like Motorola SPI, Texas Instruments SSP and National
Semiconductors Microwire, that is the serial protocol utilized for the
SPI-transfers. Depending on the DW SSI IP-core configuration the protocol
could be either fixed or selectable. If it is changebale the protocol can
be selected by means of the CTRL0.FRF field, which possible values encoded
by the dw_ssi_type enumeration. Aside with the denoted enum the field
values are also described by a set of SPI_FRF_{SPI,SSP,MICROWIRE} macros.
Thus currently the DW SPI driver has got two entities describing the same
data. Let's get rid of the enumeration one then, since first it hasn't
been used as enumeration-type but merely as a parametrized values set and
second that would unify the macro-based CSR read/write interface of the
driver. While at it convert the macro names to be more descriptive about
the protocols they represent.

A new commit in LLVM causes an error on the use of 'long double' when
'-mno-x87' is used, which the kernel does through an alias,
'-mno-80387' (see the LLVM commit below for more details around why it
does this).
drivers/power/reset/ltc2952-poweroff.c:162:28: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it

^
3 errors generated.
This happens due to the use of a 'long double' literal. The 'E6' part of
'1E6L' causes the literal to be a 'double' then the 'L' suffix promotes
it to 'long double'.
There is no visible reason for floating point values in this driver, as
the values are only assigned to integer types. Use NSEC_PER_MSEC, which
is the same integer value as '1E6L', to avoid changing functionality but
fix the error.
