2021-07-06drivers: clk: sifive: fu740-prci: replace 'pciaux' with 'pcieaux'Green Wan
Replace 'pciaux' with 'pcieaux', including name string and function prefix. The old name string, 'pciaux', might cause an error if PCIe driver is changed to use clk_get_by_name() with 'pcieaux' to get clock.

Add fu740 support. One abstract layer is added for supporting multiple chips such as fu540 and fu740. Signed-off-by: Green Wan <green.wan@sifive.com>
2021-01-05dm: Rename DM_GET_DRIVER() to DM_DRIVER_GET()Simon Glass
In the spirit of using the same base name for all of these related macros, rename this to have the operation at the end. This is not widely used so the impact is fairly small. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-08-04sifive: reset: add DM based reset driver for SiFive SoC'sSagar Shrikant Kadam
PRCI module within SiFive SoC's has register with which we can reset the sub-systems within the SoC. The resets to DDR and ethernet sub systems within FU540-C000 SoC are active low, and are hold low by default on power-up. Currently these are directly asserted within prci driver via register read/write. With the DM based reset driver support here, we bind the reset driver with clock (prci) driver and assert the reset signals of both sub-system's appropriately.

2020-08-04fu540: prci: use common reset indexes defined in binding headerSagar Shrikant Kadam
Indexes of reset signals available in PRCI driver are also defined in include/dt-bindings/reset/sifive-fu540-prci.h. So use those instead of defining new ones again within the fu540-prci driver.

2020-06-04clk: sifive: fu540-prci: Release ethernet clock resetPragnesh Patel
U-Boot ethernet works with FSBL flow where releasing ethernet clock reset is part of FSBL itself but with the SPL, We need to release ethernet clock reset explicitly for U-Boot proper. With this change Release ethernet clock reset code in FSBL might not be needed or unaffected.

2020-02-05dm: core: Require users of devres to include the headerSimon Glass
At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.

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.
