401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

f3f83ad4ca spi: omap3_spi: Fix speed and mode selection
McSPI IP provides per CS specific speed and mode selection. Therefore it
is possible to apply these settings only after CS is known. But
set_speed and set_mode can be called without bus being claimed, this
would lead driver to set up wrong CS (or previously used CS).

Fix this by apply set_speed and set_mode only if bus is already claimed.

caa4daa2ae dm: treewide: Rename 'platdata' variables to just 'plat'
We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

56c4046038 spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI*
This change allows more fine tuning of driver model based SPI support in
SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI
support in SPL and TPL via Kconfig option.

Before this change it was necessary to use:
    /* SPI Flash Configs */
    #if defined(CONFIG_SPL_BUILD)
    #undef CONFIG_DM_SPI
    #undef CONFIG_DM_SPI_FLASH
    #undef CONFIG_SPI_FLASH_MTD
    #endif

in the ./include/configs/<board>.h, which is error prone and shall be
avoided when we strive to switch to Kconfig.

The goal of this patch:

Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL).
Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must
still support non DM driver.

Another use case is the conversion of non DM/DTS SPI driver to support
DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the
distinction is needed in Kconfig (also if SPL version of the driver
supports OF_PLATDATA).

In the end of the day one would have to support following use cases (in
single driver file - e.g. mxs_spi.c):

- U-Boot proper driver supporting DT/DTS
- U-Boot proper driver without DT/DTS support (deprecated)
- SPL driver without DT/DTS support
- SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to
  run full blown DT/DTS)
- SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained
  environment with no fitImage and OF_LIBFDT support).

Some boards do require SPI support (with DM) in SPL (TPL) and some only
have DM_SPI{_FLASH} defined to allow compiling SPL.

This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI)
and provides corresponding defines in Kconfig.

b8b88e6aff spi: omap3: fix set_wordlen() reading from incorrect address for CHCONF
_omap3_spi_set_wordlen() indexed the regs->channel[] array with the
old wordlen (instead of the chipselect number) when reading the current
CHCONF register value. This meant it read from the wrong memory location,
modified that value, and then wrote it back to the correct CHCONF
register. The end result is that most slave configuration settings would
be lost, such as clock divisor, clock/chipselect polarities, etc.

c0eaffa039 spi: omap3: fix claim/release bus within DM
The claim/release bus function must not reset the whole SPI core because
settings regarding wordlen, clock-frequency and so on made by
set_wordlen, set_mode, set_speed get lost with this action. Resulting in
a non-functional SPI.

Without DM the failure didn't came up since after the spi_reset within
claim bus all the setup (wordlen, mode, ...) was called, in DM they are
called by the spi uclass.

We change now the things as following for having a working SPI instance
in DM:

- move the spi_reset(...) to the probe call in DM for having a known
hardware state after probe. Without DM we don't have a probe call, so we
issue the reset as before during the claim_bus call.

- in release bus we just reset the modulctrl to the reset-value (spi-
slave)

9cddf70ead spi: omap3: fix set_speed and set_mode dm callbacks
commit 8480792287
("spi: omap3: Skip set_mode, set_speed from claim") did break SPI
support on my AM335x board.

The named commit:

- ignored the responsible arguments (speed, mode)
The set speed/mode function must use the supplied function arguments to
work properly. With this commit we take those arguments and transfer
them to the priv-data.

- used wrong udevice pointer for getting priv data
the udevice-pointer within function argument is already the spi-bus
device, so it is wrong looking here for some parent (ocp-bus in this
case) and getting priv-pointer from there.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

a821c4af79 dm: Rename dev_addr..() functions
These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

Update the spi interface to support changing the SPI word length,

This implementation is backwards compatible by defaulting to the old
behavior of 8 bit word lengths.
Also, it required a change to the omap3_spi non static I/O functions,
but since they are not used anywhere else, no collateral changes are required.
