x86: qemu: move QFW to its own uclass

2021-04-12T21:44:55+00:00

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.

pwm: Add a driver for Chrome OS EC PWM

2021-04-10T14:08:39+00:00

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.

misc: ocotp: Update OCOTP driver for iMX8MQ B2

2021-04-08T07:18:29+00:00

i.MX8MQ B2 also has fixed value in OCOTP_READ_FUSE_DATA register,
so it does not support "fuse sense" command like B1.

sandbox: cros_ec: Only write EC state when the EC is probed

This can crash if the EC has not yet been probed. Add a check to prevent
this.

x86: Make coreboot sysinfo available to any x86 board

2021-03-27T00:59:37+00:00

It is possible to boot U-Boot for chromebook_coral either 'bare metal' or
from coreboot. In the latter case we want to provide access to the coreboot
sysinfo tables. Move the definitions into a file available to any x86
board.

dm: Rename device_get_by_driver_info_idx()

2021-03-26T04:03:08+00:00

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.
