clk: microchip: drop POLARFIRE from ARCH_MICROCHIP_POLARFIRE

2026-01-16T06:48:38+00:00

This driver is used by non-polarfire devices now, and the ARCH_MICROCHIP
symbol has been defined for some time on RISCV so drop it without any
functional change.

clk: microchip: mpfs: use regmap for clocks

2025-11-02T13:22:58+00:00

Convert the PolarFire SoC clock driver to use regmaps instead of iomem
addresses as a preparatory work for supporting the new binding for this
device that will only provide the second of the two register regions, and
will require the use of syscon regmap to access the "cfg" and "periph"
clocks currently supported by the driver.

This is effectively a revert of commit 4da2404bb003 ("clk: microchip:
mpfs: convert cfg_clk to clk_divider") and commit d815569783e6 ("clk:
microchip: mpfs: convert periph_clk to clk_gate") as it resurrects the
ops structures removed in those commits, with the readl()s and
writel()s replaced by regmap_read()s and regmap_writes()s.

clk: microchip: convert SOC_MICROCHIP_POLARFIRE to ARCH_MICROCHIP_POLARFIRE

2023-05-22T08:57:27+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 Microchip FPGA
clock drivers to use the new symbol.

clk: microchip: enable the MPFS clk driver by default if SOC_MICROCHIP_POLARFIRE

2022-12-09T01:12:08+00:00

With the intent of removing driver selects from Kconfig.socs in
arch/riscv, essential drivers that were being selected there could
instead by enabled by defaulting them to the value of the SoC's Kconfig
symbol.

Do so here & drop the depend on RISC-V - the SOC_ symbols are only
defined there anyway.

clk: microchip: mpfs: add reset controller

2022-09-14T07:55:17+00:00

Add a reset controller to PolarFire SoC's clock driver. This reset
controller is registered as an aux device and read/write functions
exported to the drivers namespace so that the reset controller can
access the peripheral device reset register.
