'Lower page 00h' is the first 128 - * bytes of address space, and always references the same - * location, independent of the page select register. - * All mapped pages are mapped into the upper 128 bytes - * (offset 128-255) of the i2c address. - * d) Devices with one I2C address (eg QSFP) use I2C address 0x50 - * (A0h in the spec), and map all pages in the upper 128 bytes - * of that address. - * e) Devices with two I2C addresses (eg SFP) have 256 bytes of data - * at I2C address 0x50, and 256 bytes of data at I2C address - * 0x51 (A2h in the spec). Page selection and paged access - * only apply to this second I2C address (0x51). - * e) The address space is presented, by the driver, as a linear - * address space. For devices with one I2C client at address - * 0x50 (eg QSFP), offset 0-127 are in the lower - * half of address 50/A0h/client[0].

('page -1' is the lower - * half, offset 0-127). - * f) For devices with two I2C clients at address 0x50 and 0x51 (eg SFP), - * the address space places offset 0-127 in the lower - * half of 50/A0/client[0], offset 128-255 in the upper - * half.
