clk: starfive: Fix RESET_STARFIVE_JH7110 can't be selected in a specified case

2023-05-03T01:34:49+00:00

When (ARCH_STARFIVE [=n] && COMPILE_TEST [=y] && RESET_CONTROLLER [=n]),
RESET_STARFIVE_JH7110 can't be selected by CLK_STARFIVE_JH7110_SYS
and CLK_STARFIVE_JH7110_AON.

Add a condition `if RESET_CONTROLLER` to fix it. Also, delete redundant
selected options of CLK_STARFIVE_JH7110_AON because these options are
already selected by the dependency.

clk: starfive: Delete the redundant dev_set_drvdata() in JH7110 clock drivers

2023-04-18T01:14:10+00:00

The dev_set_drvdata() is no longer needed after we used a wrapper
struct to get the data in auxiliary driver.

clk: starfive: Avoid casting iomem pointers

2023-04-13T22:45:46+00:00

Let's use a wrapper struct for the auxiliary_device made in
jh7110_reset_controller_register() so that we can stop casting iomem
pointers. The casts trip up tools like sparse, and make for some awkward
casts that are largely unnecessary. While we're here, change the
allocation from devm and actually free the auxiliary_device memory in
the release function. This avoids any use after free problems where the
parent device driver is unbound from the device but the
auxiliuary_device is still in use accessing devm freed memory.

clk: starfive: Factor out common JH7100 and JH7110 code

2023-04-05T14:43:32+00:00

The clock control registers on the StarFive JH7100 and JH7110 work
identically, so factor out the code then drivers for the two SoCs
can share it without depending on each other. No functional change.

clk: starfive: Replace SOC_STARFIVE with ARCH_STARFIVE

2023-04-05T14:43:29+00:00

Using ARCH_FOO symbol is preferred than SOC_FOO.
Set obj-y for starfive/ in Makefile, so the StarFive drivers
can be compiled with COMPILE_TEST=y but ARCH_STARFIVE=n.
