2023-03-17rtc: rc5t583: Convert to platform remove callback returning voidGravatar Uwe Kleine-König 1-3/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-02-25rtc: pm8xxx: add support for nvmem offsetGravatar Johan Hovold 1-12/+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.

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.

2023-02-22rtc: efi: Avoid spamming the log on RTC read failureGravatar Ard Biesheuvel 1-1/+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.

This branch is almost exclusively dead code removal based on those annotations. Some device driver removals went through separate subsystem trees, but the majority is in the same branch, in order to better handle dependencies between the patches and avoid breaking bisection. Unfortunately that leads to merge conflicts against other changes in the subsystem trees, but they should all be trivial to resolve by removing the files.

2023-02-09rtc: jz4740: Register clock provider for the CLK32K pinGravatar Paul Cercueil 2-1/+57
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.
