Hi,

Not completely related to that patch series but I was wondering if you
had access to that particular RTC.

The rtc-d1307 driver claims to also support rx8025 but my guess is that
is is not necessary anymore. Could you check which one we should keep?

rx8025 in rtc-ds1307 driver doesn't support alarm, so we should keep
rtc-rx8025.  But rtc-rx8025 driver currently requires both
I2C_FUNC_SMBUS_BYTE_DATA and I2C_FUNC_SMBUS_I2C_BLOCK for i2c adapter
while rx8025 in rtc-ds1307 driver requires one of them.  So we can't
simply remove rx8025 support from rtc-ds1307 now.

Maybe we can introduce emulated read/write_i2c_block_data functions
for this.
