dm: cros_ec: Convert cros_ec_i2c over to driver model

2015-01-30T00:10:01+00:00

Move this driver to use driver model and update the snow configuration to
match.

dm: cros_ec_spi: Remove old pre-driver-model code

2015-01-30T00:09:57+00:00

This is no-longer needed since all platforms use SPI for cros_ec.

dm: cros_ec: Don't require protocol 3 support

2015-01-30T00:09:57+00:00

I2C is now deprecated on ARM platforms and there are no devices that use it
with the v3 protocol. We can't require v3 support if we want to support I2C.
Adjust the error handling to suit.

dm: spi: Move slave details to child platdata

2015-01-30T00:09:56+00:00

At present we go through various contortions to store the SPI slave's chip
select in its private data. This only exists when the slave is active so
must be set up when it is probed. Until the device is probed we don't
actually know what chip select it will appear on.

However, now that we can support per-child platform data, we can use that
instead. This allows us to set up the chip select when the child is bound,
and avoid the messy contortions.

Unfortunately this is a fairly large change and it seems to be difficult to
break it down further.

dm: cros_ec: Remove use of fdtdec GPIO support

These functions are going away, so use the new uclass support instead.

i2c_eeprom: include to fix build error

x86: Add a simple superio driver for SMSC LPC47M

2014-12-14T05:32:05+00:00

On most x86 boards, the legacy serial ports (io address 0x3f8/0x2f8)
are provided by a superio chip connected to the LPC bus. We must
program the superio chip so that serial ports are available for us.

dm: Add a simple EEPROM driver

2014-12-11T20:18:43+00:00

There seem to be a few EEPROM drivers around - perhaps we should have a
single standard one? This simple driver is used for sandbox testing, but
could be pressed into more active service.

It supports reading and writing from a small data store.

mxc_ocotp: Do not disable the OCOTP clock after every access

2014-12-01T09:20:19+00:00

Leave the OCOTP turned on, so that we subsequent access do not fail.

After enabling the thermal driver on a mx6sxsabresd board:

U-Boot 2015.01-rc1-18267-g99d4189-dirty (Nov 24 2014 - 12:59:01)

Board: MX6SX SABRE SDB
I2C:   ready

In:    serial
Out:   serial
Err:   serial
Net:
(hang)

As the thermal driver accesses the ocotp registers, its clock will be disabled
afterwards.

Then when the MAC address is read (also from ocotp registers) it will cause a
hang.

Do not disable the ocotp clock to prevent this problem.
