OMAP3: Fix missing GPMC_CONFIG_CS0_BASE

2009-08-09T22:12:43+00:00

Applying two indepenent OMAP3 patches resulted in missing
GPMC_CONFIG_CS0_BASE. Patch "omap3: embedd gpmc_cs into gpmc
config struct" removes GPMC_CONFIG_CS0_BASE, independent patch
"omap3: bug fix for NOR boot support" introduces it's usage.
Re-introduce GPMC_CONFIG_CS0_BASE.

mxc-mmc: sdhc host driver for MX2 and MX3 proccessor

2009-08-09T21:47:38+00:00

This is a port of Linux driver for SDHC host controller hardware
found on Freescale's MX2 and MX3 processors. Uses new generic MMC
framework (CONFIG_GENERIC_MMC) and it looks like there are some
problems with a framework (at least on LE cpus). Some of these
problems are addressed in the following patches.

omap3: use only fixed-size types inside ctrl_structs

2009-08-08T09:36:29+00:00

replace variable types in ctrl_structs for omap3 by those with
fixed size (u8, u16, u32).
Additional ifndef-protection is needed by examples which do not
compile when including asm/types.h

OMAP I2C Fix the sampling clock.

2009-07-28T06:52:33+00:00

This problem is seen on Zoom1 and Zoom2 in the startup and
when i2c probe is used

Before :

Err:   serial

After :

OMAP3 Zoom1# i2c probe
Valid chip addresses: 48 49 4A 4B

The addresses are for the twl4030.

The prescalar that converts the function clock to the sampling
clock is hardcoded to 0.  The reference manual recommends 7
if the function clock is 96MHz.

Instead of just changing the hardcoded values, the prescalar
is calculated from the value I2C_IP_CLK.

The i2c #defines are in kHz.  The speed passed into the
i2c init routine is in Hz.  To be consistent, change the
defines to be in Hz.

The timing calculations are based on what is done in the
linux 2.6.30 kernel in drivers/i2c/buses/i2c_omap.c as
apposed to what is done in TRM.

The major variables in the timing caculations are
specified as #defines that can be overriden as required.

The variables and their defaults are

I2C_IP_CLK				SYSTEM_CLOCK_96
I2C_INTERNAL_SAMPLING_CLK		19200000
I2C_FASTSPEED_SCLL_TRIM			6
I2C_FASTSPEED_SCLH_TRIM			6
I2C_HIGHSPEED_PHASE_ONE_SCLL_TRIM	I2C_FASTSPEED_SCLL_TRIM
I2C_HIGHSPEED_PHASE_ONE_SCLH_TRIM	I2C_FASTSPEED_SCLH_TRIM
I2C_HIGHSPEED_PHASE_TWO_SCLL_TRIM	I2C_FASTSPEED_SCLL_TRIM
I2C_HIGHSPEED_PHASE_TWO_SCLH		I2C_FASTSPEED_SCLH_TRIM

This was runtime verified on Zoom1, Zoom2, Beagle and Overo.
The 400kHz and 3.4M cases were verifed on test Zoom1,
Zoom2, Beagle and Overo configurations.

Testing for omap2 will be done in a second step as Nishanth
and Jean-Christophe commented.
