Subject: mfd: Add support for X-Powers AC200
The X-Powers AC200 is a mixed signal multi-purpose chip, which provides
audio DAC/ADCs, a CVBS video encoder, a 100Mbit/s Ethernet PHY and a
real-time clock. Its control registers can be accessed via I2C or
Allwinner's RSB bus.
Beside this chip being used on some older boards (for instance the Remix
Mini PC), it is quite wide spread due to its die being co-packaged on the
Allwinner H6 and H616 SoCs, which use its audio, video and PHY
functionality.
Aside from the RTC, the other functions do not need constant
hand-holding via the I2C registers, but rather need to be configured and
enabled only once.
We model the control side of this chip using the MFD subsystem. This
driver here just provides the parent device for the various subfunctions,
and takes care of enabling clocks and reset, but also provides the regmap,
which the respective child drivers will use.

Subject: net: phy: Add support for AC200 EPHY
The X-Powers AC200 mixed signal chip contains a 100Mbit/s Ethernet PHY.
While its sporting a usable default setup, and can be controlled by the
generic IEEE802.3-C22 PHY driver, the BSP sets up some extra registers,
which this driver here covers.
Add a PHY driver matching the AC200 EPHY ID registers, and which
programs some PHY registers according to the BSP code.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: driver: allwinner h618 emac
Subject: drv:net:stmmac:sun8i: Add H618 EMAC support
Add GMAC (sunxi-gmac) driver for Allwinner H618 and related SoCs,
along with the internal EPHY driver (sunxi-ephy) and GPIO enhancements
for PHY reset control.
The GMAC driver supports the Allwinner Ethernet MAC controller with
RMII/RGMII interfaces and works with both internal EPHY and external
PHYs including the AC200.
