Revert "dm: pinctrl: Prevent (re-)configuring pins when already done before relocation"

2019-01-11T15:03:42+00:00

This reverts commit a7f4b4b344396590845e6552c82829ef68ef9f89.

As reported by Alex Kiernan the above optimization introduces a
regression in the below use case where:

1. Device has defined 'u-boot,dm-spl' property (@ eMMC DTS node)

2. The device downloads its MLO/SPL via UART (not eMMC - the eMMC pinmux
pins are NOT probed/configured in MLO/SPL).

3. The loaded via UART MLO/SPL wants to load Linux from eMMC. In this case
the DM core and pinctrl uclass checks 'u-boot,dm-spl' and don't
configure pins (as it thinks that those were initialized in MLO/SPL).

As we are very close to release - please revert this commit.

dm: pinctrl: Add pinctrl_decode_pin_config_dm().

2019-01-02T21:38:44+00:00

pinctrl_decode_pin_config_dm() is basically a feature-equivalent
implementation of pinctrl_decode_pin_config(), which operates
on struct udevice devices and uses the dev_read_*() API.

dm: pinctrl: Prevent (re-)configuring pins when already done before relocation

2018-12-27T02:21:07+00:00

This commit prevents from re-configuring pins if those were configured
before relocation.

Some pins - like UART or DDR must be setup before relocation
(as they have 'u-boot,dm-pre-reloc' property set in DTS). Without this
change, those pins are re-configured after relocation (pre_reloc_only = 0,
so we do not "continue").
Such behavior may be a problem for DDR PAD configuration, as they might
be already leveled/tuned with original setup).

dm: pinctrl: Add pinctrl_get_pin_name and pinctrl_get_pins_count

2018-11-16T21:51:55+00:00

Add pinctrl_get_pin_name() and pinctrl_get_pins_count() methods
to obtain pin's name and pin's muxing given a pin reference.

This will be used by the new pinmux command.

pinctrl: do not set_state for device without valid ofnode

Not all the udevice have a available DT node, eg. rksdmmc@ff500000.blk
which add by mmc_bind(), these device do not have/need set pinctrl

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

libfdt: move headers to and

2018-03-05T15:16:28+00:00

Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
  include/libfdt.h         -> include/linux/libfdt.h
  include/libfdt_env.h     -> include/linux/libfdt_env.h

and replaces include directives:
  #include       -> #include 
  #include   -> #include

dm: ofnode: rename ofnode_read_prop() to ofnode_get_property()

2017-07-11T16:08:20+00:00

This function returns the pointer to the value of a node property.
The current name ofnode_read_prop() is confusing.  Follow the naming
of_get_property() from Linux.

The return type (const u32 *) is wrong.  DT property values can be
strings as well as integers.  This is why of_get_property/fdt_getprop
returns an opaque pointer.
