This patch series converts GE boards to use DM features.
Most of the patches are GE board specific to modify the board code to
use the DM drivers, or modify the device tree.
There are a few new features:
patch 11 & 12: Add i2c_eeprom partitioning via device tree
patch 16 & 17: Add an i2c chip addr offset overflow mask to allow offsets to
effectively steal chip addresses. This handles a common i2c addressing
mode used on various devices.
patch 18: Add i2c eeprom bootcount driver
patch 36 & 37: add da9063 pmic and regulators

Fixes commit: 0b09f7b15052bb419e318e38da453be46e5a13e5, which converted
to DM_VIDEO, but requires more memory.

Use vidconsole for output to the LCD, now that DM_VIDEO is used. Write
white text on a black background, like before migrating to DM_VIDEO.

DM for PCI pulls DM for ethernet that also needs other changes described
below to build u-boot and keep existing functionality - ability to update
MAC addresses of FEC ethernet adapter and I210 adapter connected to the
Marvell switch.
- fec_mxc driver with DM needs PHYLIB;
- configuration items are moved from ge_bx50v3.h to ge_bx50v3_defconfig;
- FEC is marked as eth0 because it is always present, so indices changed:
I210 are still probed in the same order;
- board_eth_init() was used by legacy ethernet, setup for enet iomux and
pcie is moved to the board_late_init();
- pci_init() is called from the board_late_init() to initiate PCI bus
probing, so I210 devices are propagated to the device tree;

Remove old (pre-DM) i2c setup code. The old iomux setup was setting up
the wrong pins.
Enable DM i2c.
Enable MXC DM i2c driver.
Enable compat i2c api while we migrate other i2c devices to DM i2c.
Define CONFIG_SYS_MALLOC_F_LEN so that DM is available in pre-reloc.
Make GPIO banks available during preloc, since initialisation is done
in board_early_init_f().
Add gpio_request() calls to satisfy the DM_GPIO compatibility API.

To: u-boot
Some devices (2 wire eeproms for example) use some bits from the chip
address to represent the high bits of the offset instead of or as well
as using multiple bytes for the offset, effectively stealing chip
addresses on the bus.
Add a chip offset mask that can be set for any i2c chip which gets
filled with the offset overflow during offset setup.

Add bootcount node, linking to i2c eeprom "bootcount" partitions for
storage.
Enable i2c eeprom bootcount backend storage.
Enable bootcount command and use it for failbootcmd.

Remove unused power configuration.
The code never calls pmic_init, so this was not being used, and stops

Now that all i2c drivers are using DM i2c, we can disable the
compatibility api.

Move UART initialisation to a stand-alone function for consistency with
other boards.
Drop PPD_UART_PAD_CTRL since it matches defaults.

Enable DM_VIDEO for mx53ppd. This also requires DM_REGULATOR_FIXED and
DM_PWM for the backlight, and `failbootcmd' is changed to use lcdputs.
Remove unused MX53PPD_LCD_POWER.

The 3-bit "command", or register, is encoded within the device address.
Configure the device accordingly, and pass command in DM I2C read/write
calls correctly.

Remove old (incorrect) setup_iomux_lcd.
Enable backlight via display enable handler.
Use cls command to initiate display in HW agnostic manner.

Please can you update the i2c tests to cover this new feature?

Can you add an example value here, or point to some documentation on

I also have a board with DA9063 and was looking for support in U-Boot. I
found patches from Martin Fuzzey [1] and pulled them in almost as is and
found them to work just fine.
Unfortunately I didn't have time to resend them yet, but you can find
the rebased patches here: [2].
On a first glance your implementation looks different, so it seems you
didn't use Martin's patches. Though the resulting features probably will
be similar.
I only had a very quick look and one difference seems to be that your
regulator implementation supports the AUTO and SYNC mode, while Martin's
version supports AUTO, SYNC and SLEEP. There might be other differences.
What do you think? Which version would be better?
Also find a few comments below, though I didn't do a full review, yet.
Thanks,
Frieder

It would be good to be able to enable the driver for U-Boot proper and
SPL separately. So this should be CONFIG_$(SPL_)DM_PMIC_DA9063.

It would be good to be able to enable the driver for U-Boot proper and

(+cc Martin Fuzzey)
Huh, I had not seen that.
Martin's versions looks more complete than mine, so I would say go with
that one.
Martin: any objections to including your patches in here? I dont mind
pushing it through and handling any review comments etc. I am keen to
get get this upstreamed.

No that's fine by me. It would be good to get them upstream.

Sure, will do.
Having looked at the i2c testing available in test/dm/i2c.c, I'm
struggling to see how the current tests are valid.
The changes in offset leng for 3 and 4 byte offsets don't set the
correct offset length in dm_test_i2c_offset.
Also, there is no visibility of the effect under test to verify the
correct behaviour. It seems to be relying on predictable offset mapping
in to an assumed 256 byte storage in drivers/misc/i2c_eeprom_emul.c,
but as long as the mapping is consistent between read and write, it
could be all sorts of wrong and the test would not show any issue.
Also there appears to be a bug in the loop for offset mapping, I think
it should be ">=", rather than ">". Currently wouldn't it overflow the
storage if an offset of 256 is used?
Am I missing something in how it is meant to work? If not, I can modify
the tests while I'm adding a new one for the new addressing mode, I
just wanted to check first.
Thanks for the review, Ill fix the rest up for v2.

I think the best approach is to modify the tests in a separate patch,
then add your new patch.
