2019-07-10ARM: uniphier: de-couple SC macros into base address and offsetMasahiro Yamada
The SC_* macros represent the address of SysCtrl registers. For a planned new SoC, its base address will be changed. Turn the SC_* macros into the offset from the base address. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.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>
2017-12-12ARM: uniphier: use FIELD_PREP for PLL settingsMasahiro Yamada
It is tedious to define both mask and bit-shift. <linux/bitfield.h> provides a convenient way to get access to register fields with a single shifted mask. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-12-12ARM: uniphier: compute SSCPLL values more preciselyMasahiro Yamada
Use DIV_ROUND_CLOSEST(). To make the JK value even more precise, I used a bigger coefficient, then divide it by 512. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-12-12ARM: uniphier: fix SSCPLL init code for LD11 SoCDai Okamura
Commit 682e09ff9f35 ("ARM: uniphier: add PLL init code for LD20 SoC") missed to write the computed value to the SSCPLLCTRL2 register.

2017-01-22ARM: uniphier: replace <common.h> with <linux/delay.h> where possibleMasahiro Yamada
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").

2016-10-29ARM: uniphier: remove unneeded mdelay() in PLL setting functionMasahiro Yamada
This delay is already cared by the callers of this function. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-09-19ARM: uniphier: add PLL init code for LD20 SoCMasahiro Yamada
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>
