This patch adds a limited pulse-width modulator to sandbox's Chromium OS
Embedded Controller emulation. The emulated PWM device supports multiple
channels but can only set a duty cycle for each, as the actual EC
doesn't expose any functionality or information other than that. Though
the EC supports specifying the PWM channel by its type (e.g. display
backlight, keyboard backlight), this is not implemented in the emulation
as nothing in U-Boot uses this type specification.
This emulated PWM device is then used to test the Chromium OS PWM driver
in sandbox. Adding the required device node to the sandbox test
device-tree unfortunately makes it the first PWM device, so this also
touches some other tests to make sure they still use the sandbox 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.

At present if U-Boot proper uses driver model for I2C, then SPL has to

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

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.

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

At present we use a 'node' pointer in the of-platadata phandle_n_arg

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

The FSP-S changes the ITSS priorities. The code that tries to save it

relocates in between the save and restore. This means that the driver

This patch extends dtoc to use struct driver_info when populating

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.

The ESM (Error Signal Monitor) is used on certain PMIC versions to
handle error signals propagating from rest of the system. If these

The ESM (Error Signaling Module) is used to route error signals within

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.

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.
