35746c0138 stm32mp: stm32f7_i2c: use calloc instead of kmalloc
Kmalloc is using memalign allocation function. It is not necessary to
align this structure so to save bytes, we move to calloc.

And kmalloc function can't be used in SPL early stage (in board_init_f())

004b4cdaec i2c: mvtwsi.c: Fix set speed
Previous patch for this driver breaks i2c initialization.

commit 8bcf12ccce ("i2c: mvtwsi.c: Avoid NULL dereference")

If actual_speed is passed as NULL in this function:
static void __twsi_i2c_init(struct mvtwsi_registers *twsi, int speed,
			    int slaveadd, uint *actual_speed)
than __twsi_i2c_set_bus_speed never get called. This causes i2c clock
to run on default speed - 2MHz (measured with oscilloscope). This is issue
on some boards, sunxi for example, since on I2C0 bus PMU is connected.

The bootlogs with and without the patch are as follows:

cab8a27d80 i2c: at91_i2c: remove the .probe_chip function
The .probe_chip function is supposed to probe an i2c device on the bus to
determine whether a device is answering to a particular address.
at91_i2c_probe_chip() did not do anything resembling this and always
returned 0.

It looks as though at91_i2c_probe_chip() was intended to be a .probe
function for the controller, as it was copied-and-pasted to become
at91_i2c_probe() in 0bc8f640a4.

Removing the at91_i2c_probe_chip() function makes the higher layer
(i2c_probe_chip()) try a zero-length read transfer to test for the
presence of a device instead, which does work.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

        |          | SCL/SDA    |          |-------------- |           |

        |          |            |          | Bus segment 2 |           |
        |  Linux   | GPIO 1..N  |   MUX    |---------------   Devices
        |          |------------|          |               |           |
        |          |            |          | Bus segment M

         ----------              ----------                  - - - - -

SCL/SDA of the master I2C bus is multiplexed to bus segment 1..M
according to the settings of the GPIO pins 1..N.
