* arm: socfpga: reset: Add function to reset add peripheralsMarek Vasut2015-08-08-0/+13
| | | | | | | 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>
* arm: socfpga: reset: Repair bridge reset handlingMarek Vasut2015-08-08-4/+4
| | | | | | | | | | | 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.

* arm: socfpga: reset: Replace ad-hoc reset functionsMarek Vasut2015-08-08-50/+0
| | | | | | | | 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>
* arm: socfpga: reset: Implement unified function to toggle resetMarek Vasut2015-08-08-23/+35
| | | | | | | | 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>
* arm: socfpga: reset: Start reworking the SoCFPGA reset managerMarek Vasut2015-08-08-11/+11
| | | | | | | | | | 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>
* ARM: socfpga: move SoC sources to mach-socfpgaMasahiro Yamada2015-05-07-0/+139
Our recent trend is to collect SoC files into arch/arm/mach-(SOC). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
