2023-10-24T03:27:46+00:00

This can reduce the kernel image size in multiplatform configurations.

clk: Explicitly include correct DT includes

2023-07-19T20:13:16+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

clk: sifive: Use devm_platform_ioremap_resource()

2023-06-15T00:20:13+00:00

Convert platform_get_resource(),devm_ioremap_resource() to a single
call to devm_platform_ioremap_resource(), as this is exactly what this
function does.

clk: sifive: make SiFive clk drivers depend on ARCH_ symbols

2023-04-10T20:00:59+00:00

As part of converting RISC-V SOC_FOO symbols to ARCH_FOO to match the
use of such symbols on other architectures, convert the SiFive clk
drivers to use the new symbol.

clk: sifive: select by default if SOC_SIFIVE

2022-10-17T21:07:11+00:00

With the aim of dropping direct selects of drivers from Kconfig.socs,
default the SiFive clock drivers to the value of SOC_SIFIVE.

clk: sifive: Move all stuff into SoCs header files from C files

2022-03-15T22:56:28+00:00

Improve PRCI driver to reduce the complexity, we remove the SoCs C files
by putting all stuff in each SoCs header files, and include these
SoCs-specific header files in core of PRCI. It can also avoid the W=1
kernel build warnings about variable defined but not used
[-Wunused-const-variable=], like commit 487dc7bb6a0c ("clk: sifive:
fu540-prci: Declare static const variable 'prci_clk_fu540' where it's
used") does.

clk: sifive: Add SoCs prefix in each SoCs-dependent data

2022-03-15T22:56:28+00:00

This patch is prerequisite for moving SoCs C files into SoCs header
files. Currently, fu540-prci.c and fu740-prci.c use same names for
several macro definitions and variables, it would cause redefinition
error when we trying to include all stuff in sifive-prci.c. In this
patch, we also remove the temporary macro definitions which are
added by previous patch.

clk: sifive: duplicate the macro definitions for the time being

2022-03-15T22:56:28+00:00

This is a temporary patch in whole patch set. We are going to change the
macro name in dt-binding, in order to avoid breaking the driver build
and git bisect, add these macro definitions for the time being, and we
will remove them later.

We use reset-simple in this patch so that pcie driver can use
devm_reset_control_get() to get this reset data structure and use
reset_control_deassert() to deassert pcie_power_up_rst_n.
