0fd3d91152 dm: Use access methods for dev/uclass private data
Most drivers use these access methods but a few do not. Update them.

In some cases the access is not permitted, so mark those with a FIXME tag
for the maintainer to check.

We use 'priv' for private data but often use 'platdata' for platform data.

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.

87d07ccc23 sandbox: cros_ec: Basic support for EC_CMD_GET_NEXT_EVENT
Since commit 6900797678 ("cros_ec: Support keyboard scanning with
EC_CMD_GET_NEXT_EVENT") the cros-ec-keyb driver has started using this
command, but the sandbox EC emulator does not recognize it and
continuously prints:

    ** Unknown EC command 0x67

This patch makes the sandbox driver send basic responses to the command,
but the response only supports keyboard scans for now.

The EC side of this command stores and returns events from a queue, and
returns -EC_RES_UNAVAILABLE when there are no new events. This should be
possible to implement by hooking into the SDL event queue (perhaps via
sandbox_sdl_poll_events). Implementing that is a bit harder to do since
the existing sandbox code is discarding pending keyboard events, then
reading the current keyboard state.

Since the EC emulator never explicitly fails to work on this command,
the fallback to the older command will not trigger and will not be
tested anymore.

a3e458524c cros_ec: Handling EC_CMD_GET_NEXT_EVENT
With commit 6900797678 ("cros_ec: Support keyboard scanning with
EC_CMD_GET_NEXT_EVENT") check_for_keys() tries to read keyboard
strokes using EC_CMD_GET_NEXT_EVENT. But the sandbox driver does
not understand this command. We need to reply with
-EC_RES_INVALID_COMMAND to force check_for_keys() to fall back to
use EC_CMD_MKBP_STATE. Currently the driver prints

    ** Unknown EC command 0x67

in this case. With the patch the message is suppressed.

In a future patch we should upgrade the sandbox driver to provide
EC_CMD_GET_NEXT_EVENT support.

6900797678 cros_ec: Support keyboard scanning with EC_CMD_GET_NEXT_EVENT
The cros_ec_keyb driver currently uses EC_CMD_MKBP_STATE to scan the
keyboard, but this host command was superseded by EC_CMD_GET_NEXT_EVENT
and unavailable on more recent devices (including gru-kevin), as it was
removed in cros-ec commit 87a071941b89 ("mkbp: Add support for buttons
and switches.") dated 2016-07-06.

The EC_CMD_GET_NEXT_EVENT has been available since cros-ec commit
d1ed75815efe ("MKBP event signalling implementation") dated 2014-10-20,
but it looks like it isn't included in firmware-* branches for at least
link, nyan-big, samus, snow, spring, panther and peach-pit which have
defconfigs in U-Boot. So this patch falls back to the old method if the
EC doesn't recognize the newer command.

The implementation is mostly adapted from Depthcharge commit
f88af26b44fc ("cros_ec: Change keyboard scanning method.").

On a gru-kevin, the current driver before this patch fails to read the
pressed keys with:

    out: cmd=0x60: 03 9d 60 00 00 00 00 00
    in-header: 03 fc 01 00 00 00 00 00
    in-data:
    ec_command_inptr: len=-1, din=0000000000000000
    check_for_keys: keyboard scan failed

However the keyboard works fine with the newer command:

    out: cmd=0x67: 03 96 67 00 00 00 00 00
    in-header: 03 ef 00 00 0e 00 00 00

8a38abfc43 dm: Use driver_info index instead of pointer
At present we use a 'node' pointer in the of-platadata phandle_n_arg
structs. This is a pointer to the struct driver_info for a particular
device, and we can use it to obtain the struct udevice pointer itself.

Since we don't know the struct udevice pointer until it is allocated in
memory, we have to fix up the phandle_n_arg.node at runtime. This is
annoying since it requires that SPL's data is writable and adds a small
amount of extra (generated) code in the dm_populate_phandle_data()
function.

Now that we can find a driver_info by its index, it is easier to put the
index in the phandle_n_arg structures.

Update dtoc to do this, add a new device_get_by_driver_info_idx() to look
up a device by drive_info index and update the tests to match.

b95611f67e x86: apl: Fix save/restore of ITSS priorities
The FSP-S changes the ITSS priorities. The code that tries to save it
before running FSP-S and restore it afterwards does not work as U-Boot
relocates in between the save and restore. This means that the driver
data saved before relocation is lost and the new driver just sees zeroes.

Fix this by allocating space in the relocated memory for the ITSS data.
Save it there and access it from the driver after relocation.

This fixes interrupt handling on coral.

Also drop the log_msg_ret() in irq_first_device_type() since this function
can be called speculatively in places where we are not sure if there is
an interrupt controller of that type. The resulting log errors are
confusing when there is no error.

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.

b24dc83f15 misc: i2c_eeprom: implement different probe test eeprom offset
Because of this commit :
5ae84860b0 ("misc: i2c_eeprom: verify that the chip is functional at probe()")
at probe time, each eeprom is tested for read at offset 0.

The Atmel AT24MAC402 eeprom has different mapping. One i2c slave address is
used for the lower 0x80 bytes and another i2c slave address is used for the
upper 0x80 bytes. Because of this basically the i2c master sees 2 different
slaves. We need the upper bytes because we read the unique MAC address from
this EEPROM area.

However this implies that our slave address will return error on reads
from address 0x0 to 0x80.

To solve this, implemented an offset field inside platform data that is by
default 0 (as it is used now), but can be changed in the compatible table.

The probe function will now read at this offset and use it, instead of blindly
checking offset 0.

This will fix the regression noticed on these EEPROMs since the commit
abovementioned that introduces the probe failed issue.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

025543554c dm: irq: Add support for requesting interrupts
At present driver model supports the IRQ uclass but there is no way to
request a particular interrupt for a driver.

Add a mechanism, similar to clock and reset, to read the interrupts
required by a device from the device tree and to request those interrupts.

U-Boot itself does not have interrupt-driven handlers, so just provide a
means to read and clear an interrupt. This can be useful to handle
peripherals which must use an interrupt to determine when data is
available, for example.

Bring over the basic binding file as well, from Linux v5.4. Note that the
older binding is not supported in U-Boot; the newer 'special form' must be
used.

Add a simple test of the new functionality.

ba87607971 dm: irq: Add support for interrupt controller types
There can be different types of interrupt controllers in a system and some
drivers may need to distinguish between these. In general this can be
handled using the device tree by adding the interrupt information to
device nodes.

However on x86 devices we have interrupt controllers which are not tied
to any particular device and not really used in U-Boot. These still need
to be inited, so a convenient method is to give each controller a type
and allow a particular controller type to be probed.

Add support for this in sandbox along with a test.

9a03e50c5f misc: k3_avs: Add j721e support
j721e SoCs have different OPP tables. Add support for the same.

Note: DM Still has lot of voltages TBD hence the correct
values need to be programmed once they are published.

9d233b4e3e misc: k3_avs: add driver for K3 Adaptive Voltage Scaling Class 0
Adaptive Voltage Scaling is a technology used in TI SoCs to optimize
the operating voltage based on characterization data written to efuse
during production. Add a driver to support this feature for K3 line of
SoCs, initially for AM65x.

816d093c1a misc: imx8: scu: simplify code to make it extendable
clk and pinctrl will be get(probed) during each device probe,
we don't need to probe them in scu driver. Only need to bind the sub-nodes
(clk and iomuxc) of MU node with their drivers.

So drop the code to probe the clk/pinctrl, and this patch will make it
easy to add more subnodes.

f81649586d misc: microchip_flexcom: introduce microchip_flexcom driver
The Microchip Flexcom is just a wrapper which embeds a SPI controller,
an I2C controller and an USART.
Only one function can be used at a time and is chosen at boot time according
to the device tree.
The bindings are kept as in Linux.
The driver registers to MISC_UCLASS.
