In some cases U-Boot runs the same binary on different board versions.
In wandboard, for example, there are versions with the PFUZE100 PMIC
populated and others without it.
When the PMIC is not present, it is not really useful to get PMIC error,
so change the error message level to debug instead.

struct display_timings provides more informations such clock and DE
polarity, so let's refactor the code to use struct display_timings
instead of struct ctfb_res_modes, so we'll become able to get clock and

device tree (saved in desc->flags).
When these optional ops are absent, the gpio uclass use the mandatory
ops (direction_output, direction_input, get_value) and desc->flags

This commit manages the new dir flags that can be used in gpio
specifiers to indicate the pull-up or pull-down resistor
configuration for output gpio (GPIO_PULL_UP, GPIO_PULL_DOWN)
or the Open Drain/Open Source configuration for input gpio
(GPIO_OPEN_DRAIN, GPIO_OPEN_SOURCE).
These flags are already supported in Linux kernel in gpio lib.
This patch only parse and save the direction flags in GPIO
descriptor (desc->flags), it prepares the introduction of new ops
to manage them.
The GPIO uclass supports new GPIO flags from device-tree
(GPIO_XXX define in include/dt-bindings/gpio/gpio.h)
and translate them in the dir flags (GPIOD_XXX):
- GPIO_PULL_UP => GPIOD_PULL_UP
- GPIO_PULL_DOWN => GPIOD_PULL_DOWN
- GPIO_OPEN_DRAIN => GPIOD_OPEN_DRAIN
- GPIO_OPEN_SOURCE => GPIOD_OPEN_SOURCE
This patch also adds protection in the check_dir_flags function for
new invalid configuration of the dir flags.

DM change to read parent ofdata before children
Minor fixes
|
|
At present a device can read its ofdata before its parent has done the
same. This can cause problems in the case where the parent has a 'ranges'
property, thus affecting the operation of dev_read_addr(), for example.
We already probe parent devices before children so it does not seem to be
a large step to do the same with ofdata.
Make the change and update the documentation in this area.

- "/firmware"
The patch removes the strcmp call in recursive function dm_scan_fdt_live()
and also corrects a conflict with the 2 applied patches in
the commit 1712ca21924b ("dm: core: Scan /firmware node by default")
and in the commit 747558d01457 ("dm: fdt: scan for devices under
/firmware too"): the subnodes of "/firmware" (optee for example)
are bound 2 times.
