* | drivers/i2c/fsl_i2c: modify i2c_read to handle multi-byte writeShaveta Leekha2014-04-29-7/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MDIO clock needs to be initialized in u-boot code for SoCs having FMAN-v3(v3H or v3L) controller due to below reasons -On SoCs that have FMAN-v3H like B4860, default value of MDIO_CLK_DIV bits in mdio_stat(mdio_cfg) register generates mdio clock too high (much higher than 2.5MHz), violating the IEEE specs. -On SOCs that have FMAN-v3L like T1040, default value of MDIO_CLK_DIV bits is zero, so MDIO clock is disabled. So, for proper functioninig of MDIO, MDIO_CLK_DIV bits needs to be properly initialized. Also this type of initialization is generally done in PBI(pre-bootloader) phase using rcw.But for chips like T1040 which support deep-sleep, such type of initialization cannot be done in PBI phase due to the limitation that during deep-sleep resume, FMAN (MDIO) registers are not accessible in PBI phase. So, mdio clock initailization must be done as part of u-boot. This initialization code is implemented in memac_phy.c which gets compiled only for SoCs having FMANv3, so no extra compilation flag is required.
