Add Reset Manager driver support for Stratix SoC Signed-off-by: Chin Liang See <chin.liang.see@intel.com> Signed-off-by: Ley Foon Tan <ley.foon.tan@intel.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-05-18arm: socfpga: Restructure reset manager driverLey Foon Tan
Restructure reset manager driver in the preparation to support A10. Move the Gen5 specific code to gen5 files. Signed-off-by: Ley Foon Tan <ley.foon.tan@intel.com>
2015-09-04arm: socfpga: Assure ISWGRP 0 and 1 are initedMarek Vasut
This fix makes sure that the ISWGRP0 and ISWGRP1 registers are correctly inited. In case those registers are not initialized, it is not possible to access the registers synthesised in the FPGA through the bridges. Any such access produces data abort.

2015-08-08arm: socfpga: reset: Add function to reset add peripheralsMarek Vasut
Add socfpga_per_reset_all() function to reset all peripherals but the L4 watchdog. This is needed in the SPL. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: reset: Repair bridge reset handlingMarek Vasut
The current bridge reset code, which de-asserted the bridge reset, was activelly polling whether the FPGA is programmed and ready and in case it was (!), the code called hang(). This makes no sense at all. Repair it such that the code instead checks whether the FPGA is programmed, but without any polling involved, and only if it is programmed, it de-asserts the reset.

2015-08-08arm: socfpga: reset: Replace ad-hoc reset functionsMarek Vasut
Replace all those ad-hoc reset functions, which were all copies of the same invocation of clrbits_le32() anyway, with one single unified function, socfpga_per_reset(), with necessary parameters. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: reset: Implement unified function to toggle resetMarek Vasut
Implement function socfpga_per_reset(), which allows asserting or de-asserting reset of each reset manager peripheral in a unified manner. Use this function throughout reset manager. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: reset: Start reworking the SoCFPGA reset managerMarek Vasut
Implement macro SOCFPGA_RESET(name), which produces an abstract reset number. Implement macros which allow extracting the reset offset in permodrstN register and which permodrstN register the reset is located in from this abstract reset number. Use these macros throughout the reset manager. Signed-off-by: Marek Vasut <marex@denx.de>

Our recent trend is to collect SoC files into arch/arm/mach-(SOC). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
