rtc: nuvoton: Compatible with NCT3015Y-R and NCT3018Y-R

2024-01-18T00:05:33Z

The NCT3015Y-R and NCT3018Y-R use the same datasheet but have different topologies as follows. - Topology (Only 1st i2c can set TWO bit and HF bit) In NCT3015Y-R, rtc 1st i2c is connected to a host CPU rtc 2nd i2c is connected to a BMC In NCT3018Y-R, rtc 1st i2c is connected to a BMC rtc 2nd i2c is connected to a host CPU In order to be compatible with NCT3015Y-R and NCT3018Y-R, - In probe, If part number is NCT3018Y-R, only set HF bit to 24-Hour format. Else, do nothing - In set_time, If part number is NCT3018Y-R && TWO bit is 0, change TWO bit to 1, and restore TWO bit after updating time.

rtc: da9063: Make IRQ as optional

2024-01-18T00:00:21Z

On some platforms (eg: RZ/{G2UL,Five} SMARC EVK), there is no IRQ populated by default. Add irq optional support. Signed-off-by: Biju Das Reviewed-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/20240105145344.204453-2-biju.das.jz@bp.renesas.com Signed-off-by: Alexandre Belloni

rtc: max31335: Fix comparison in max31335_volatile_reg()

2024-01-17T23:59:32Z

Clang warns (or errors with CONFIG_WERROR=y): drivers/rtc/rtc-max31335.c:211:36: error: use of logical '||' with constant operand [-Werror,-Wconstant-logical-operand] 211 | if (reg == MAX31335_TEMP_DATA_MSB || MAX31335_TEMP_DATA_LSB) | ^ ~~~~~~~~~~~~~~~~~~~~~~ drivers/rtc/rtc-max31335.c:211:36: note: use '|' for a bitwise operation 211 | if (reg == MAX31335_TEMP_DATA_MSB || MAX31335_TEMP_DATA_LSB) | ^~ | | 1 error generated. This clearly should be a comparison against reg. Fix the comparison so that max31335_volatile_reg() does not always return true.
