| * rtc: pm8xxx: add support for nvmem offsetJohan Hovold2023-02-251-12/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On many Qualcomm platforms the PMIC RTC control and time registers are read-only so that the RTC time can not be updated. Instead an offset needs be stored in some machine-specific non-volatile memory, which the driver can take into account. Add support for storing a 32-bit offset from the Epoch in an nvmem cell so that the RTC time can be set on such platforms.

| * | rtc: abx80x: Add nvmem supportSean Anderson2023-02-241-0/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the 256-byte internal RAM. There are two windows which can be used to access this RAM: 64 bytes at 0x40 (the "standard" address space) and 128 bytes at 0x80 (the "alternate" address space). We use the standard address space because it is also accessible over SPI (if such a port is ever done). We are limited to 32-byte reads for SMBus compatibility, so there's no advantage to using the alternate address space. There are some reserved bits in the EXTRAM register, and the datasheet doesn't say what to do with them. I've opted to skip a read/modify/write and just write the whole thing. If this driver is ever converted to regmap, this would be a good place to use regmap_update_bits.

| * | rtc: efi: Avoid spamming the log on RTC read failureArd Biesheuvel2023-02-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are cases where the EFI runtime services may end up in a funny state, e.g., due to a crash in the variable services, and this affects other EFI runtime services as well. That means that, even though GetTime() should not return an error, there are cases where it might, and there is no point in logging such an occurrence multiple times. This works around an issue where user space -apparently- keeps hitting on /dev/rtc if it fails to read the h/w clock, resulting in a tsunami of log spam and a non-responsive system as a result.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On JZ4770 and JZ4780, the CLK32K pin is configurable. By default, it is configured as a GPIO in input mode, and its value can be read through GPIO PD14. With this change, clients can now request the 32 kHz clock on the CLK32K pin, through Device Tree. This clock is simply a pass-through of the input oscillator's clock with enable/disable operations. This will permit the WiFi/Bluetooth chip to work on the MIPS CI20 board, which does source one of its clocks from the CLK32K pin.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make sure to disable the alarm before updating the four alarm time registers to avoid spurious alarms during the update. Note that the disable needs to be done outside of the ctrl_reg_lock section to prevent a racing alarm interrupt from disabling the newly set alarm when the lock is released.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RTC core never calls rv8803_set_alarm with an invalid alarm time, so if an invalid alarm time > 0 is set, external factors must have corrupted the RTC's alarm time and possibly other registers. Play it safe by marking the date/time invalid, so all registers are reinitialized on a ->set_time. This may cause existing setups to lose time if they so far set only date/time, but ignored that the alarm registers had an invalid date value, e.g.: rtc rtc0: invalid alarm value: 2020-3-27 7:82:0 These systems will have their ->get_time return -EINVAL till ->set_time initializes the alarm value (and sets a new time).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The wake interrupt only fires when the system is in a suspend state. Fortunately we have another interrupt that fires in a non-suspend state at the L2 controller UPG_AUX_AON. Add support for this interrupt line so we can use the alarm in a non-wake context.
