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: Use reset-simple in prci driver for PCIe driver

2021-05-04T11:26:09Z

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.

clk: sifive: Add a driver for the SiFive FU740 PRCI IP block

2020-12-16T20:22:59Z

Add driver code for the SiFive FU740 PRCI IP block. This IP block handles reset and clock control for the SiFive FU740 device and implements SoC-level clock tree controls and dividers. The link of unmatched as follow, and the U740-C000 manual would be present in the same page as soon. https://www.sifive.com/boards/hifive-unmatched This driver contains bug fixes and contributions from Henry Styles Erik Danie Pragnesh Patel Signed-off-by: Zong Li Reviewed-by: Pragnesh Patel Acked-by: Palmer Dabbelt Cc: Henry Styles Cc: Erik Danie Cc: Pragnesh Patel Link: https://lore.kernel.org/r/20201209094916.17383-4-zong.li@sifive.com [sboyd@kernel.org: Include header to silence sparse] Signed-off-by: Stephen Boyd

clk: sifive: Use common name for prci configuration

2020-12-16T20:22:59Z

Use generic name CLK_SIFIVE_PRCI instead of CLK_SIFIVE_FU540_PRCI. This patch is prepared for fu740 support.

clk: sifive: restrict Kconfig scope for the FU540 PRCI driver

2019-05-21T18:34:45Z

Restrict Kconfig scope for SiFive clock and reset IP block drivers such that they won't appear on most configurations that are unlikely to support them. This is based on a suggestion from Pavel Machek . Ideally this should be dependent on CONFIG_ARCH_SIFIVE, but since that Kconfig directive does not yet exist, add dependencies on RISCV or COMPILE_TEST for now.
