| * | clk: sifive: restrict Kconfig scope for the FU540 PRCI driver | Paul Walmsley | 2019-05-21 | 1 | -0/+1 |
| | | | | | | | | | | | | | | | | | 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 <pavel@ucw.cz>. 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.

| * | clk: sifive: add a driver for the SiFive FU540 PRCI IP block | Paul Walmsley | 2019-05-03 | 1 | -0/+18 |
| Add driver code for the SiFive FU540 PRCI IP block. This IP block handles reset and clock control for the SiFive FU540 device and implements SoC-level clock tree controls and dividers. Based on code written by Wesley Terpstra <wesley@sifive.com>: https://github.com/riscv/riscv-linux/commit/999529edf517ed75b56659d456d221b2ee56bb60 Boot and PLL rate change were tested on a SiFive HiFive Unleashed board. This version includes several changes requested by Stephen Boyd <sboyd@kernel.org>.
