In case of repeated START condition, the restart has to be kicked
before clear status (MSR register). If it is kicked after clear status,
R-Car I2C may transfer data (TXD register) or receive data (RXD register)
instead of transferring slave address (MAR register).Signed-off-by: Ryo Kataoka

Some slow I2C devices like Power Monitor(ZM7304) at times
do not work well with low timeout value, so I2C bus get stuck
during read cycle with this device, changing it to 100ms from
10ms works fineA lot of other i2c drivers like mxc and i2c drivers of BOOTROM
also use relax timeouts to give sufficient ticks to work well
with slower devicesSigned-off-by: Shaveta Leekha

ppc4xx i2c master gets stuck on errors while repeated start is
active. Can be easily reproduced by "i2c md" on an unpopulated
i2c address. There is not stop condition given, scl remains
pulled low.
The only way out seems to be doing a stop manually and then a
soft reset.Signed-off-by: Dirk Eibach

Debugging some i2c trouble I saw on my scope that repeated
start is not working properply. The 4xx even held clock pulled down
after transfers. Having a look in the driver I realized
that IIC_CNTL_RPST is set on that part of the transfer that should
begin with a repeated start. But repeated start is about not sending a
stop condition, so IIC_CNTL_RPST has to be set on the last transfer
before the repeated start happens.Signed-off-by: Dirk Eibach

Add a driver for the designware serial UART used on sunxi. This just
redirects to the normal ns16550 driver.Add a stdout-path to the device tree so that the correct UART is chosen.

In preparation for the SoCFPGA support of the designware I2C driver,
convert this driver to the common CONFIG_SYS_I2C framework.This patch converts all users of this driver, this is:
- ST spearxxx boards
- AXS101 (ARC700 platform)I couldn't test this patch on those boards. Only compile tested for all
spear boards. And tested on SoCFPGA.Signed-off-by: Stefan Roese

This patch permeates the struct i2c_adapter throughout the driver,
so that it can be used to determine which adapter should be used.
Note that the driver still supports only one adapter. Note that
the patch does shuffle mxs_i2c_set_bus_speed() to the top of the
driver, but the function remains unchanged.Signed-off-by: Marek Vasut
