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>
