treewide: convert devfdt_get_addr() to dev_read_addr()

2020-07-25T20:46:57+00:00

When you enable CONFIG_OF_LIVE, you will end up with a lot of
conversions.

To generate this commit, I used coccinelle excluding drivers/core/,
include/dm/, and test/

The semantic patch that makes this change is as follows:

  
  @@
  expression dev;
  @@
  -devfdt_get_addr(dev)
  +dev_read_addr(dev)

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

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.

w1: Add driver for i.MX bus master controller

2019-01-01T13:12:18+00:00

Two variants of controllers are supported:
V1 (bitwise only) found in
	i.MX21, i.MX27, i.MX31, i.MX51
V2 (byte operations) found in
	i.MX25, i.MX35, i.MX50, i.MX53

Only tested on i.MX53 hardware but in both modes
(by modifying the device tree).

w1: fix occasional enumeration failure

2018-12-06T22:15:15+00:00

Sometimes enumeration fails (about 1 in 50 times on my custom board).

The underlying reason is probably electrical but Linux does not have
the problem.

Comparing the Linux / u-boot implementations shows that Linux
retries the error case whereas u-boot aborts early.

Removing the early abort in u-boot fixes the problem.

w1: fix data abort if no one wire bus master present

2018-11-01T14:02:10+00:00

When the "w1 bus" command is used with no bus master present
a data abort may occur.

This is because uclass_first_device() returns zero, but sets the output
struct udevice pointer to NULL in the no device found case.

Fix w1_get_bus() to account for this and return an error code
as is expected by the callers.
