2017-12-01powerpc: dts: P1010: Add endianness property to flexcan nodePankaj Bansal
The flexcan driver assumed that flexcan controller is big endian for powerpc architecture and little endian for other architectures. But this is not universally true. flexcan controller can be little or big endian on any architecture. Therefore the flexcan driver has been modified to check for "big-endian" device tree property for controllers that are big endian. consequently add the property to freescale P1010 SOC device tree.

2017-06-28powerpc/fsl: Add generic compatible string for I2C EEPROMJavier Martinez Canillas
The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.

Limitations: This patch covers only models 171 and 173 No plans to support CPLD timers Know issues: All four PHYs work in polling mode Configuration is missing for: PCI IDSEL and PCI Interrupt definition Support is missing for: Cache and memory controllers (which are very similar to the 85xx ones but right now I don't know if we can re-use their support) Watchdog, USB, NVRAM, NOR, NAND, EEPROMs, VME, PMC/XMC and RTC Signed-off-by: Alessio Igor Bogani <alessio.bogani@elettra.eu> Signed-off-by: Scott Wood <oss@buserror.net>
