* fsl_i2c: add workaround for the erratum I2C A004447Chunhe Lan2013-08-20-3/+11
| | | | | | | | | | | | | | | | | | | | | | | This workaround is for the erratum I2C A004447. Device reference manual provides a scheme that allows the I2C master controller to generate nine SCL pulses, which enable an I2C slave device that held SDA low to release SDA. However, due to this erratum, this scheme no longer works. In addition, when I2C is used as a source of the PBL, the state machine is not able to recover. At the same time, delete the reduplicative definition of SVR_VER and SVR_REV. The SVR_REV is the low 8 bits rather than the low 16 bits of svr. And we use the CONFIG_SYS_FSL_A004447_SVR_REV macro instead of hard-code value 0x10, 0x11 and 0x20. The CONFIG_SYS_FSL_A004447_SVR_REV = 0x00 represents that one version of platform has this I2C errata. So enable this errata by IS_SVR_REV(svr, maj, min) function.

Move Freescale specific register define to arch/powerpc/include/asm/fsl_pci.h and update the register offset define for T4240. 2. add the status/control register define use status/control register to judge the link status 3. The original code uses 'Programming Interface' field to judge if PCIE is EP or RC mode, however, T4240 does not support this functionality. According to PCIE specification, 'Header Type' offset 0x0e is used to indicate header type, so for PCIE controller, the patch changes code to use 'Header Type' field to identify if the PCIE is RC or EP mode.

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add special function that executes a specially crafted circular DMA descriptor. The function doesn't wait for the descriptor to finish the transfer, since the descritor never finishes. This is useful when operating a SmartLCD through the LCDIF interface, as the LCDIF does not give us any means to have continuous refresh of the SmartLCD. Instead, the RUN bit in the LCDIF CTRL register must be triggered manually. This can be worked around by starting an DMA transfer which continuously sets the RUN bit. This function allows starting exactly such transfer.

This behavior only appears in certain boot modes (notably QSPI boot). Attempting to configure the PL with the loopback bit set will result in timeouts and will prevent successful configuration. In order to avoid this problem, and to avoid dependency on the version of the FSBL used to boot the system, ensure that the loopback enable bit is cleared when loading the driver.
