[PATCH v2 0/3] Conclusive KSTR-SAMA5D27 support
Hi all,
this is v2 of the Conclusive KSTR-SAMA5D27 support series.
Patch [1/3] now also renames the EEPROM serial number function and moves its documentation from .c file to the .h. We should be fine doing that, as - to my knowledge - no other part of U-Boot seems to be using this symbol, as evidenced by the missing prototype.
Patch [2/3] is new. It is the direct result of moving i2c as a child of flexcom (see below).
Patch [3/3] now also addresses multiple dts issues. In particular, all node access is now being done through label references, unused nodes have been removed, and the i2c now goes explicitly through flexcom.
Artur Rojek (3): common: add prototype & rename populate_serial_number() arm: dts: at91: sama5: Add flexcom4 node board: Add support for Conclusive KSTR-SAMA5D27

Rename populate_serial_number() to a more descriptive eeprom_read_serial() and provide the missing function prototype.
This is useful for boards that wish to read their serial number from EEPROM at init.

v2: - remove redundant license text from at91-kstr-sama5d27.dts - when defining properties in .dts, reference nodes by labels - drop nodes for usb0 and pmic, as these aren't used by drivers - switch i2c to flexcom driver and make the necessary dts changes - sort includes in at91-kstr-sama5d27.dts alphabetically
