5b0b43e0e2 x86: qemu: move QFW to its own uclass
We move qfw into its own uclass and split the PIO functions into a
specific driver for that uclass.  The PIO driver is selected in the
qemu-x86 board config (this covers x86 and x86_64).

include/qfw.h is cleaned up and documentation added.

1b9ee2882e pwm: Add a driver for Chrome OS EC PWM
This PWM is used in rk3399-gru-bob and rk3399-gru-kevin to control
the display brightness. We can only change the duty cycle, so on
set_config() we just try to match the duty cycle that dividing duty_ns
by period_ns gives us. To disable, we set the duty cycle to zero while
keeping the old value for when we want to re-enable it.

The cros_ec_set_pwm_duty() function is taken from Depthcharge's
cros_ec_set_bl_pwm_duty() but modified to use the generic pwm type.
The driver itself is very loosely based on rk_pwm.c for the general pwm
driver structure.

The devicetree binding file is from Linux, before it was converted to
YAML at 5df5a577a6b4 ("dt-bindings: pwm: Convert google,cros-ec-pwm.txt
to YAML format") in their repo.

cc469b7086 dm: Rename device_get_by_driver_info_idx()
This function finds a device by its driver_info index. With
of-platdata-inst we do not use driver_info, but instead instantiate
udevice records at build-time.

However the semantics of using the function are the same in each case:
the caller provides an index and gets back a device.

So rename the function to device_get_by_ofplat_idx(), so that it can be
used for both situations. The caller does not really need to worry about
the details.

d1f3abe1e7 dm: i2c: allow disabling driver model in SPL
At present if U-Boot proper uses driver model for I2C, then SPL has to
also. While this is desirable, it places a significant barrier to moving
to driver model in some cases. For example, with a space-constrained SPL
it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves
adjusting some drivers.

This patch introduces a separate Kconfig symbols for enabling DM_I2C and
DM_I2C_GPIO support in SPL.

This will also help to get away from dirty workarounds to
achieve non-DM I2C support for SPL, which is currently used in some
board header files like:

ifdef CONFIG_SPL_BUILD
undef CONFIG_DM_I2C
endif

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.

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
    in-data: 00 00 00 00 00 00 00 00 00 00 00 00 00 00
    ec_command_inptr: len=14, din=00000000f412df30
    key_matrix_decode: num_keys = 0
      0 valid keycodes found
    out: cmd=0x67: 03 96 67 00 00 00 00 00
    in-header: 03 df 00 00 0e 00 00 00
    in-data: 00 00 00 00 00 00 00 00 00 00 00 00 10 00
    ec_command_inptr: len=14, din=00000000f412df30
    key_matrix_decode: num_keys = 1
      valid=1, row=4, col=11
        keycode=28
      1 valid keycodes found

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.

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.

21d651fb29 sandbox: Complete migration away from os_malloc()
Now that we can use direct access to the system malloc() in sandbox, drop
the remaining uses of os_malloc().

The only one remaining now is for the RAM buffer, which we do want to be
at a known address, so this is intended.

336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

61b29b8268 dm: core: Require users of devres to include the header
At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

db41d65a97 common: Move hang() to the same header as panic()
At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.
