2018-04-27reset: uniphier: add SATA reset control support and change SATA-PHY IDKunihiko Hayashi
Add reset lines for SATA controller on UniPhier SoCs. This adds support for Pro4 and PXs3 in addition to PXs2. And this changes the ID of the reset line for SATA-PHY on PXs2. Since some SoCs have two controller instances with a common PHY, this moves the ID of SATA-PHY for consistency.

2018-04-27reset: uniphier: fix USB clock line for LD20Masahiro Yamada
For LD20, the bit 5 of the offset 0x200c turned out to be a USB3 reset. The hardware document says it is the GIO reset despite LD20 has no GIO bus, confusingly. Also, fix confusing comments for PXs3.

2017-08-11reset: uniphier: do not use per-SoC macro for system reset blockMasahiro Yamada
This macro turned out not so useful as I had expected. Hardware engineers said they would change reset bit assignments for every SoC going forward. This means we can not share the macros among SoCs. Just use primitive macros. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

2016-10-22reset: uniphier: rename MIO reset to SD reset for Pro5, PXs2, LD20 SoCsMasahiro Yamada
I made a mistake as for naming for this block. The MIO block is not implemented for these 3 SoCs in the first place. The current naming will be a trouble if an SoC with both MIO and SD-ctrl blocks appear in the future. This driver has just been merged in the previous merge window. Rename it before the release.
