* ARM: uniphier: set up charge pump current for MPLL of LD11 SoCMasahiro Yamada2017-02-23-0/+24
| | | | Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: deassert RST_n of eMMC device for LD11/LD20Masahiro Yamada2017-02-23-1/+23
| | | | | | | | | | | | | For LD11 and LD20 SoCs, the RST_n pin is asserted by default. If the EXT_CSD[162], bit[1:0] (RST_n_ENABLE) is fused, the eMMC device would stay in the reset state until its RST_n pin is deasserted by software. Currently, this is cared by an ad-hoc way because the eMMC hardware reset provider is not supported in U-Boot for now. This code should be re-written once the "mmc-pwrseq-emmc" binding is supported.

* ARM: uniphier: rework spl_boot_device() and related codeMasahiro Yamada2017-02-23-2/+1
| | | | | | | | The current implementation has ugly switch statements here and there, and duplicates similar code. Rework it using table lookups for SoC data and reduce code duplication. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: add PXs3 SoC supportMasahiro Yamada2017-01-22-0/+8
| | | | | | Initial support for PXs3 SoC. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: replace <common.h> with <linux/delay.h> where possibleMasahiro Yamada2017-01-22-4/+5
| | | | | | | | | The <common.h> includes too many headers. Actually, these files needed to include it for udelay() declaration. Now we can replace it with <linux/delay.h> thanks to commit 5bc516ed661a ("delay: collect {m, n, u}delay declarations to include/linux/delay.h"). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: replace <linux/err.h> with <linux/errno.h>Masahiro Yamada2017-01-22-2/+2
| | | | | | | | These files only need error number macros. Actually, IS_ERR(), PTR_ERR(), ERR_PTR(), etc. are not useful for U-Boot. Avoid unnecessary header includes. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: refactor spl_init_board()Masahiro Yamada2017-01-18-3/+15
| | | | | | | Merge init-*.c into a single file using a table of callbacks because the initialization flow is almost common among SoCs. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: refactor board_init()Masahiro Yamada2017-01-18-15/+1
| | | | | | | The code here is cluttered due to the switch statement. Introduce a table of callbacks to clean up the initialization code across SoCs. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: split out UMC clock enableMasahiro Yamada2017-01-17-56/+73
| | | | | | | | The clock enable bits for UMC are more SoC-specific than for the other hardware blocks. Separate the UMC clocks and the other clocks for better code reuse across SoCs. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: remove unneeded argument of uniphier_ld20_pll_init()Masahiro Yamada2017-01-17-3/+1
| | | | | | | At first, we thought the LD20 PLL setting would be board dependent, but this argument turned out unneeded after all. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: do not run harmful code for USB boot mode of LD11 ES3Masahiro Yamada2016-10-29-3/+5
| | | | | | | | | The USB boot without the stand-by MPU is available on ES3 or later of LD11 SoC, but the code in this if-conditional block must not be run when booting from USB. Check if the boot device is USB, and skip the code in the case. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: enable clocks to MIO/STDMAC on LD11 if USB is enabledMasahiro Yamada2016-10-29-0/+11
| | | | | | | | At the moment, the clk driver is not clever enough to automatically enable parent clocks like Linux. Enable the STDMAC clock explicitly if USB is enabled. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: enable SSC for more PLLs for LD20 SoCMasahiro Yamada2016-10-29-13/+11
| | | | | | | | For Electro-Magnetic Compatibility. Set CPLL, SPLL2, MPLL, VPPLL, GPPLL, DPLL* to SSC rate 1 percent. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: remove unneeded mdelay() in PLL setting functionMasahiro Yamada2016-10-29-2/+0
| | | | | | This delay is already cared by the callers of this function. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: remove unnecessary EHCI reset deassertionMasahiro Yamada2016-10-18-8/+6
| | | | | | | It is now deasserted by the reset controller driver. Drop the ad-hoc code. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: enable SSC for DPLL (DRAM PLL) on LD11 SoCMasahiro Yamada2016-10-10-0/+1
| | | | | | For Electro-Magnetic Compatibility test. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: add PLL init code for LD11 SoCMasahiro Yamada2016-09-23-2/+51
| | | | | | | | | | - Initialize PLLs (SPL initializes only DPLL to save the precious SPL memory footprint) - Adjust CPLL/MPLL to the final tape-out frequency - Set the Cortex-A53 clock to the maximum frequency since it is running at 500MHz (SPLL/4) on startup Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: add PLL init code for LD20 SoCMasahiro Yamada2016-09-19-2/+197
| | | | | | | | Initialize the DPLL (PLL for DRAM) in SPL, and others in U-Boot proper. Split the common code into pll-base-ld20.c for easier re-use. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: collect clock/PLL init code into a single directoryMasahiro Yamada2016-09-19-0/+392
| | | | | | | | Now PLLs for DRAM controller are initialized in SPL, and the others in U-Boot proper. Setting up all of them in a single directory will be helpful when we want to share code between SPL and U-Boot proper. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: move PLL init code to U-Boot proper where possibleMasahiro Yamada2016-09-19-4/+315
| | | | | | | | The PLL for the DRAM interface must be initialized in SPL, but the others can be delayed until U-Boot proper. Move them from SPL to U-Boot proper to save the precious SPL memory footprint. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: add clock/reset settings for xHCI of ProXstream2Masahiro Yamada2016-07-24-1/+6
| | | | | | | Deassert resets and enable clock signals of xHCI blocks if the corresponding CONFIG is enabled. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: add PH1-LD11 SoC supportMasahiro Yamada2016-05-26-0/+29

* ARM: uniphier: add PH1-LD20 SoC supportMasahiro Yamada2016-04-24-0/+15
| | | | | | This is the first ARMv8 SoC from Socionext Inc. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* ARM: uniphier: rename function names ph1_* to uniphier_*Masahiro Yamada2016-04-01-4/+4
| | | | | | | Eliminate the "ph1"_ prefixes from function names because "uniphier_" describes the SoC familiy better. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: drop PH1- prefix from CONFIG options and file namesMasahiro Yamada2016-03-24-7/+7
| | | | | | | | The current CONFIG names like "CONFIG_ARCH_UNIPHIER_PH1_PRO4" is too long. It would not hurt to drop "PH1_" because "UNIPHIER_" already well specifies the SoC family. Also, rename files for consistency. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: switch over to generic EHCI driverMasahiro Yamada2016-02-14-4/+4
| | | | | | | | | | | | The UniPhier EHCI driver (drivers/usb/host/ehci-uniphier.c) does nothing special but set the base address and handle reset/clock. Since commit 4feefdcfe916 ("usb: add clock support for generic EHCI"), the generic one (drivers/usb/host/ehci-generic.c) can do those, too. We no longer need to stick to the dedicated driver.

* ARM: uniphier: move headers out of include/mach directoryMasahiro Yamada2016-01-13-8/+12
| | | | | | | These headers are only included locally in arch/arm/mach-uniphier/. There is no reason to export them by putting in the mach/ directory. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* Various Makefiles: Add SPDX-License-Identifier tagsTom Rini2015-11-10-0/+4
| | | | | | | | | | | After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one. This adds tags to ones that lack them and converts a few that had full (or in one case, very partial) license blobs into the equivalent tag.

* ARM: uniphier: allow to enable multiple SoCsMasahiro Yamada2015-09-25-0/+103
Before this commit, the Kconfig menu in mach-uniphier only allowed us to choose one SoC to be compiled. Each SoC has its own defconfig file for the build-test coverage. Consequently, some defconfig files are duplicated with only the difference in CONFIG_DEFAULT_DEVICE_TREE and CONFIG_{SOC_NAME}=y. Now, most of board-specific parameters have been moved to device trees, so it makes sense to include init code of multiple SoCs into a single image as long as the SoCs have similar architecture. In fact, some SoCs of UniPhier family are very similar: - PH1-LD4 and PH1-sLD8 - PH1-LD6b and ProXstream2 (will be added in the upcoming commit) This commit will be helpful to merge some defconfig files for better maintainability.
