clk: sifive: select by default if SOC_SIFIVE

2022-10-17T21:07:11Z

With the aim of dropping direct selects of drivers from Kconfig.socs, default the SiFive clock drivers to the value of SOC_SIFIVE. Signed-off-by: Conor Dooley Link: https://lore.kernel.org/r/20221005171348.167476-2-conor@kernel.org Signed-off-by: Stephen Boyd

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

2022-03-15T22:56:28Z

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

2022-03-15T22:56:28Z

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

2022-03-15T22:56:28Z

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.
