u-boot.git/drivers/i2c, branch v2013.04

Merge branch 'master' of git://git.denx.de/u-boot-arm

2013-03-18T18:37:18+00:00

Albert's rework of the linker scripts conflicted with Simon's making
everyone use __bss_end.  We also had a minor conflict over
README.scrapyard being added to in mainline and enhanced in
u-boot-arm/master with proper formatting.

Conflicts:
	arch/arm/cpu/ixp/u-boot.lds
	arch/arm/cpu/u-boot.lds
	arch/arm/lib/Makefile
	board/actux1/u-boot.lds
	board/actux2/u-boot.lds

	board/dvlhost/u-boot.lds
	board/freescale/mx31ads/u-boot.lds
	doc/README.scrapyard
	include/configs/tegra-common.h

Build tested for all of ARM and run-time tested on am335x_evm.

Tegra: I2C: Add T114 clock support to tegra_i2c driver

2013-03-14T18:06:41+00:00

T114 has a slightly different I2C clock, with a new (extra) divisor
in standard/fast mode and HS mode. Tested on my Dalmore, and the I2C
clock is 100KHz +/- 3Hz on my Saleae Logic analyzer.

Added a new entry in compat_names for T114 I2C since it differs
from the previous Tegra SoCs. A flag is set when T114 I2C HW is
found so new features like the extra clock divisor can be used.

I2C: S3C24X0: Bug fixes in i2c_transfer

2013-03-12T18:33:11+00:00

This patch corrects the following issues

1) Write the correct M/T Stop value to I2CSTAT after i2c write.
   According to the spec, after finish the data transmission, we should
   write a M/T Stop (I2C_MODE_MT | I2C_TXRX_ENA) to I2CSTAT instead of
   a M/R Stop (I2C_MODE_MR | I2C_TXRX_ENA).
2) Not split the write to I2CSTAT into 2 steps in i2c read.
   According to the spec, we should write the combined M/R Start value to
   I2CSTAT after setting the slave address to I2CDS
3) Fix the mistake of making an equality check to an assignment.
   In the case of I2C write with the zero-length address, while tranfering the
   data, it should be an equality check (==) instead of an assignment (=).

ppc: m68k: Move i2c1_clk, i2c2_clk to arch_global_data

2013-02-04T14:05:42+00:00

Move these fields into arch_global_data and tidy up. This is needed for
both ppc and m68k since they share the i2c driver.

The local functions in the mxs i2c driver are not marked static, make it so.
