fefac0b064 dm: acpi: Enhance acpi_get_name()
For many device types it is possible to figure out the name just by
looking at its uclass or parent. Add a function to handle this, since it
allows us to cover the vast majority of cases automatically.

However it is sometimes impossible to figure out an ACPI name for a device
just by looking at its uclass. For example a touch device may have a
vendor-specific name. Add a new "acpi,name" property to allow a custom
name to be created.

With this new feature we can drop the get_name() methods in the sandbox
I2C and SPI drivers. They were only added for testing purposes. Update the
tests to use the new values.

def88bce09 spi: fsl_qspi: Support to use full AHB space on i.MX
i.MX platforms provide large AHB mapped space for QSPI, each
controller has 256MB. However, current driver only maps small
size (AHB buffer size) of AHB space, this implementation
causes i.MX failed to boot M4 with QSPI XIP image.

Add config CONFIG_FSL_QSPI_AHB_FULL_MAP (default enabled for i.MX)
to address above problem.

When the config is set:
1. Full AHB space is divided to each CS.
2. A dedicated LUT entry is used for AHB read only.
3. The MODE instruction in LUT is replaced to standard ADDR instruction
4. The address in spi_mem_op is used to SFAR and AHB read

51f1263d89 dtoc: extend dtoc to use struct driver_info when linking nodes
In the current implementation, when dtoc parses a dtb to generate a struct
platdata it converts the information related to linked nodes as pointers
to struct platdata of destination nodes. By doing this, it makes
difficult to get pointer to udevices created based on these
information.

This patch extends dtoc to use struct driver_info when populating
information about linked nodes, which makes it easier to later get
the devices created. In this context, reimplement functions like
clk_get_by_index_platdata() which made use of the previous approach.

addf358bac core: add support for U_BOOT_DRIVER_ALIAS
Currently when using OF_PLATDATA the binding between devices and drivers
is done trying to match the compatible string in the node with a driver
name. However, usually a single driver supports multiple compatible strings
which causes that only devices which its compatible string matches a
driver name get bound.

To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro,
which generates no code at all, but allows an easy way to declare driver
name aliases. Thanks to this, dtoc could be improve to look for the driver
name based on its alias when it populates the U_BOOT_DEVICE entry.

e3e2470fdd drivers: rename drivers to match compatible string
When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.

In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.

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.

25e4d94f45 spi: sifive: Fix QPP transfer
The guessed reason is that the existing logic of filling
tx fifo with data, rx fifo with NULL for tx transfer and
filling rx fifo with data, tx fifo with NULL for rx transfer
is not clear enough to support the Quad Page Program.
   
SiFive SPI controllers have specific sets of watermark
registers and SPI I/O directions bits in order to program
SPI controllers clear enough to support all sets of operating
modes.
   
Here is the exact programing sequence that would follow on this
patch and tested via SPI-NOR and MMC_SPI.
   
- set the frame format proto, endian
- set the frame format dir, set it for tx and clear it for rx
- TX transfer:
  fill tx fifo with data.
  wait for TX watermark bit to clear.
- RX transfer:
  fill tx fifo with 0xff.
  write nbytes to rx watermark register
  wait for rx watermark bit to clear.
  read the rx fifo data.

So, this patch adopts this program sequence and fixes the existing
I/O direction bit.

622b913ea1 spi: sifive: Fix format register proto field
SiFive SPI controller has a proto bit field in frame format
register which would be used to configure the SPI I/O protocol
lines used on specific transfer. 

Right now the driver is configuring this proto using slave->mode,
for all types of transctions. This makes the driver unable to
function since the proto needs to configure dynamically for
each and every transaction separately at runtime.

Now, the controller driver supports per transfer via spi-mem
exec_opo, so add the fmt_proto flag and fill the per transfer
buswidth so that the controller configures the proto bit at
runtime.

This patch fixes the SPI controller works with SPI NOR flash
on quad read with page program.

b7d6e104fb spi: sifive: Add spi-mem exec op
SiFive SPI controller is responsible to handle the
slave devices like mmc spi and spi nor flash.

The controller is designed such a way that it would
handle the slave transactions based on the I/O protocol
numbers, example if spi nor slave send quad write opcode
it has to send alone with I/O protocol number of 4 and
if it try to send data it has to send I/O protocol number
along with 4 line data.

But the current spi-xfer code from spi-mem is combining
the opcode and address in a single transaction, so the
SPI controller will be unable to identify the I/O protocol
number of opcode vs address.

So, add the spi-mem exec_op with spi-xfer of opcode, address
and data as a separate transaction. This doesn't remove
the .xfer of dm_spi_ops since mmc spi will make use of it.

Note: This code might have moved to the spi-mem core area
once we have done the dedicated tests on other controllers
and have real reason to move.

e67cd814ee spi: sifive: Tidy up dm_spi_slave_platdata variable
Usually variable name slave is used for spi_slave structure
and slave_plat for the dm_spi_slave_platdata.

Let's follow this meaningful notation by replacing slave
with slave_plat for dm_spi_slave_platdata structure.

790c1699b2 spi: spi-mem: Add SPI_MEM_NO_DATA to the spi_mem_data_dir enum
Commit: 0ebb261a0b2d ("spi: spi-mem: Add SPI_MEM_NO_DATA to the spi_mem_data_dir enum")
in linux.

When defining spi_mem_op templates we don't necessarily know the size
that will be passed when the template is actually used, and basing the
supports_op() check on op->data.nbytes to know whether there will be
data transferred for a specific operation is not possible.

Add SPI_MEM_NO_DATA to the spi_mem_data_dir enum so that we can base
our checks on op->data.dir instead of op->data.nbytes.

This also fixes a bug identified with the atmel-quaspi driver.
The spi-nor core, when erasing sectors, fills the spi_mem_op template
using SPI_MEM_OP_NO_DATA, which initializes all the data members with
value zero. This is wrong because data.dir is treated as SPI_MEM_DATA_IN,
which translates in our driver to read accesses for erases (RICR), while
the controller expects write accesses (WICR).

0a9c287497 spi: cadence-qspi: Move ref clock calculation to probe
"assigned-clock-parents" and "assigned-clock-rates" DT properties take
effect only after ofdata_to_platdata() when clk_set_defaults() is called
in device_probe(). Therefore clk get rate() would return a wrong value
in ofdata_to_platdata() when compared with probe. Hence it needs to be
moved to probe.

Tested on u-boot-ti/next.

91afd36f38 spi: Transform the FSL QuadSPI driver to use the SPI MEM API
To support the SPI MEM API, instead of modifying the existing U-Boot
driver, this patch adds a port of the existing Linux driver.
This also has the advantage that porting changes and fixes from Linux will
be easier.
Porting of driver left most of the functions unchanged while few of the
changes are:
-Remove lock(mutexes) and irq handler as u-boot is a single core execution.
-Remove invalid masterid as it was required specially for multicore
execution in LS2088ARDB which is not the case in u-boot.
-Remove clock support as changing spi speed is not supported in uboot and
nor in linux.

Currently tested on LS1088ARDB, LS1012ARDB, LS1046ARDB, LS1046AFRWY,
LS1043AQDS, LS1021ATWR, LS2088ARDB, I.MX6ULL EVK.
