rtc: jz4740: Register clock provider for the CLK32K pin

2023-02-09T22:38:00+00:00

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.

ARM: s3c: remove s3c24xx specific hacks

2023-01-16T08:26:05+00:00

A number of device drivers reference CONFIG_ARM_S3C24XX_CPUFREQ or
similar symbols that are no longer available with the platform gone,
though the drivers themselves are still used on newer platforms,
so remove these hacks.

rtc: isl12026: drop obsolete dependency on COMPILE_TEST

2022-12-15T22:34:31+00:00

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

rtc: isl12022: switch to using regmap API

2022-10-12T22:17:22+00:00

The regmap abstraction allows us to avoid the private i2c transfer
helpers, and also offers some nice utility functions such as the
regmap_update_bits family.

While at it, simplify the code even more by not keeping track of
->write_enabled: rtc_set_time is not a hot path, so one extra i2c read
doesn't hurt (regmap_update_bits elides the write when the bits are
already as desired).
