2019-07-19clk: sifive: Sync-up main driver with upstream LinuxAnup Patel
The DT bindings of SiFive clock driver in upstream Linux has changes. As-per latest DT bindings, the clock driver takes two parent clocks and compatible string has also changed. This patch sync-up SiFive clock driver implementation as-per upstream Linux so that we now use latest DT bindings.

2019-07-19clk: sifive: Sync-up WRPLL library with upstream LinuxAnup Patel
Now that SiFive clock driver is merged in upstream Linux, we sync-up WRPLL library used by SiFive clock driver with upstream Linux sources. Signed-off-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-07-19clk: sifive: Factor-out PLL library as separate moduleAnup Patel
To match SiFive clock driver with latest Linux, we factor-out PLL library as separate module under drivers/clk/analogbits. Signed-off-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-05-09clk: sifive: fu540-prci: Change include orderJagan Teki
Like clk_get_by_index, there is requirement for clk_get_by_index_nodev. In this case to make common code functionalities for dev and nodev, clk_get_by_index is trying to get the index of clock by passing ofnode instead of actual dev like current gpio uclass does. In these scenarios with current order of include files the fu540-prci driver is unable to find CONFIG_ENV_SIZE. In file included from arch/riscv/include/asm/u-boot.h:23:0, from include/dm/of.h:10, from include/dm/ofnode.h:12, from include/clk.h:11, from include/clk-uclass.h:13, from drivers/clk/sifive/fu540-prci.c:32: include/environment.h:145:19: error: 'CONFIG_ENV_SIZE' undeclared here (not in a function); did you mean 'CONFIG_CMD_XIMG'? #define ENV_SIZE (CONFIG_ENV_SIZE - ENV_HEADER_SIZE) So, fix consists of changing the order of include files in fu540-prci.c to include first common.h file.

2019-02-27clk: Add SiFive FU540 PRCI clock driverAnup Patel
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> found in commit 999529edf517ed75b56659d456d221b2ee56bb60 of: https://github.com/riscv/riscv-linux Boot and PLL rate change were tested on a SiFive HiFive Unleashed board.
