mvtwsi: Remove unnecessary twsi_baud_rate and twsi_slave_address globals

2014-05-14T10:59:12+00:00

These are used only once, so their is no need to have them global.

This also stops mvtwsi from using any bss vars making it easier to use
before dram init (to talk to the pmic to set the dram voltage).

mvtwsi: Fix clock programming

2014-05-14T10:58:55+00:00

The TWSI_FREQUENCY macro was wrong in 2 ways:
1) It was casting the result of the calculations to an u8, while i2c clk
rates are often >= 100Khz which won't fit in a u8, drop the cast.
2) It had an extra factor of 2 in the divider which neither the datasheet nor
the Linux driver have.

The comment for the default value was wrongly saying that m lives in
bits 4-7, while in reality it is in bits 3-6, as can be seen from the correct
shift by 3 used in i2c_init().

While at it remove the unused twsi_actual_speed variable.

drivers/i2c/fsl_i2c: modify i2c_read to handle multi-byte write

2014-04-29T05:10:58+00:00

Most of the I2C slaves support accesses in the typical style
that is : read/write series of bytes at particular address offset.
These transactions look like:"
(1) START:Address:Tx:Offset:RESTART:Address[0..4]:Tx/Rx:data[0..n]:STOP"

However there are certain devices which support accesses in
terms of the transactions as follows:
(2) "START:Address:Tx:Txdata[0..n1]:Clock_stretching:
        RESTART:Address:Rx:data[0..n2]"
Here Txdata is typically a command and some associated data,
similarly Rxdata could be command status plus some data received
as a response to the command sent.

Type (1) transactions are currently supportd in the
i2c driver using i2c_read and i2c_write APIs. I2C EEPROMs,
RTC, etc fall in this category.

To handle type (2) along with type (1) transactions,
i2c_read() function has been modified.

driver/mxc_i2c: Move static data structure to global_data

2014-04-29T05:10:27+00:00

This driver needs a data structure in SRAM before SDRAM is available.
This is not alway the case using .data section. Moving this data
structure to global_data guarantees it is writable.

i2c, davinci: move i2c_defs.h to the drivers/i2c directory

2014-04-17T21:24:38+00:00

This patch moves the davinci i2c_defs.h file to drivers.i2c directory.
It will allow to reuse the davinci_i2c driver for TI Keystone2 SOCs.

Not used "git mv" command to move the file because small part of
it with definitions specific for Davinci SOCs has to remain in the
arch/arm/include/asm/arch-davinci.
