The TQ i.MX93 boards come in different variants. This series adds
support for the LGA variant. Fortunately the TQ boards all have a
EEPROM equipped from which the variant can be read, so this series
adds the necessary pieces to to I2C in PBL on i.MX93 and also the
common EEPROM parsing code.
The EEPROM parsing code could be reused on other TQ boards barebox
has support for, like the tqmls1046a, tqma6ul and tqma8mp. Doing so
is left for the future, for now the code is only used to detect the
i.MX93 board variant.
Sascha Hauer (8):
i2c: lpi2c: determine clk rate during probe
i2c: lpi2c: use udelay for timeout loops
i2c: lpi2c: add PBL support
pbl: eeprom: return error from eeprom_read()
common: add TQ EEPROM support
ARM: i.MX9: add i2c base address defines
ARM: i.MX9: rename TQ i.MX93 board to TQMA93XX
ARM: i.MX: tqma93xx: Add LGA board variant
