It's more natural that any write that happens to touch the reset
register should cause a reset, rather than just a write that starts at
that offset.

The current set method is broken; a simple test case is to first set
the date to something in April, then change the date to 31st May:
=> date 040412122020.34
Date: 2020-04-04 (Saturday) Time: 12:12:34
=> date 053112122020.34
Date: 2020-05-01 (Friday) Time: 12:12:34
or via the amending of the existing rtc_set_get test case similarly:
$ ./u-boot -T -v
=> ut dm rtc_set_get
Test: dm_test_rtc_set_get: rtc.c
expected: 31/08/2004 18:18:00
actual: 01/08/2004 18:18:00
The problem is that after each register write,
sandbox_i2c_rtc_complete_write() gets called and sets the internal
time from the current set of registers. However, when we get to
writing 31 to mday, the registers are in an inconsistent state (mon is
still 4), so the mktime machinery ends up translating April 31st to
May 1st. Upon the next register write, the registers are populated by
sandbox_i2c_rtc_prepare_read(), so the 31 we just wrote to mday gets
overwritten by a 1.
Fix it by writing all registers at once, and for consistency, update
the get method to retrieve them all with one "i2c transfer".

This simply consists of renaming the existing pcf2127_read_reg()
helper to follow the naming of the other
methods (i.e. pcf2127_rtc_<method name>) and changing the type of its

Similar to how the dm_rtc_{read,write} functions fall back to using
the {read,write}8 methods, do the opposite in the rtc_{read,write}8
functions.
This way, each driver only needs to provide either ->read8 or ->read
to make both rtc_read8() and dm_rtc_read() work - without this, a
driver that provides ->read() would most likely just duplicate the
logic here for implementing a ->read8() method in term of its ->read()
method. The same remarks of course apply to the write case.

Similar to dm_rtc_read(), introduce a helper that allows the caller to
write multiple consecutive 8-bit registers with one call. If the
driver provides the ->write method, use that, otherwise loop using
->write8.

Some users may want to read multiple consecutive 8-bit
registers. Instead of each caller having to implement the loop,
provide a dm_rtc_read() helper. Also, allow a driver to provide a
->read method, which can be more efficient than reading one register
at a time.

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.

The previous pcf2127 RTC chip could not read and set the correct time.
When reading the data of internal registers, the read address was the
value of register plus 1. This is because this chip requires the host
to send a stop signal after setting the register address and before
reading the register data.
This patch sets the register address using dm_i2c_write and reads
the register data using the original dm_i2c_xfer in order to generate
a stop signal after the register address is set, and fixes the bug of
the original read and write time.

This adds a compatible string for m41t82. This ensures that this driver
can be used for m41t82 in DM mode, too (asit was usable for this model in
non-DM mode before).
In addition, the HT bit has to be reset during probe, since the m41t82
chip sets it when entering battery standby mode.
This patch ensures this driver works on socfpga_socrates.
