Subject: [PATCH] drivers: net: Mark functions as static in stmmac_platform.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch marks the function stmmac_pltfr_freeze() and
stmmac_pltfr_restore() in stmmac_platform.c as static because they are
not used outside this file.
Thus, it also removes the following warnings in
ethernet/stmicro/stmmac/stmmac_platform.c:
drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c:222:5: warning: no previous prototype for ‘stmmac_pltfr_freeze’ [-Wmissing-prototypes]

Subject: [PATCH] net: stmmac: support max-speed device tree property
This patch adds support to "max-speed" property which is a standard
Ethernet device tree property. max-speed specifies maximum speed
(specified in megabits per second) supported the device.
Depending on the clocking schemes some of the boards can only support
few link speeds, so having a way to limit the link speed in the mac
driver would allow such setups to work reliably.
Without this patch there is no way to tell the driver to limit the
link speed.

This patch moves dma resource allocation to a new function
alloc_dma_desc_resources, the reason for moving this to a new function
is to keep the memory allocations in a separate function. One more reason
it to get suspend and hibernation cases working without releasing and
allocating these resources during suspend-resume and freeze-restore
cases.

Subject: [PATCH] net: stmmac: move hardware setup for stmmac_open to new
function
This patch moves hardware setup part of the code in stmmac_open to a new
function stmmac_hw_setup, the reason for doing this is to make hw
initialization independent function so that PM functions can re-use it to
re-initialize the IP after returning from low power state.
This will also avoid code duplication across stmmac_resume/restore and
stmmac_open.

Subject: [PATCH] net: stmmac: fix power management suspend-resume case
The driver PM resume assumes that the IP is still powered up and the
all the register contents are not disturbed when it comes out of low
power suspend case. This assumption is wrong, basically the driver
should not consider any state of registers after it comes out of low
power. However driver can keep the part of the IP powered up if its a
wake up source. But it can not assume the register state of the IP. Also
its possible that SOC glue layer can take the power off the IP if its
not wake-up source to reduce the power consumption.
This patch re initializes hardware by calling stmmac_hw_setup function in
resume case.

Subject: [PATCH] net: stmmac: use suspend functions for hibernation
In hibernation freeze case the driver just releases the resources like
dma buffers, irqs, unregisters the drivers and during restore it does
register, request the resources. This is not really necessary, as part
of power management all the data structures are intact, all the
previously allocated resources can be used after coming out of low
power.
This patch uses the suspend and resume callbacks for freeze and
restore which initializes the hardware correctly without unregistering
or releasing the resources, this should also help in reducing the time
to restore.
Also this patch fixes a bug in stmmac_pltfr_restore and
stmmac_pltfr_freeze where it tries to get hold of platform data via
dev_get_platdata call, which would return NULL in device tree cases and
the next if statement would crash as there is no NULL check.

Subject: [PATCH] net: stmmac: restore pinstate in pm resume.
This patch adds code to restore default pinstate of the pins when it
comes back from low power state. Without this patch the state of the
pins would be unknown and the driver would not work.
This patch also adds code to put the pins in to sleep state when the
driver enters low power state.

Subject: [PATCH] net: stmmac: notify the PM core of a wakeup event.
In PM_SUSPEND_FREEZE and WOL(Wakeup On Lan) case, when the driver gets a
wakeup event, either the driver or platform specific PM code should notify
the pm core about it, so that the system can wakeup from low power.
In cases where there is no involvement of platform specific PM, it
becomes driver responsibility to notify the PM core to wakeup the
system.
Without this WOL with PM_SUSPEND_FREEZE does not work on STi based SOCs.

The stmmac driver does not enable the main clock during the probe phase.
If the clock was not enabled by the boot loader or was disabled by the
kernel, hardware features and the MDIO bus would not be probed properly.

Subject: [PATCH] net: stmmac: Add support for optional reset control
The DWMAC has a reset assert line, which is used on some SoCs. Add an
optional reset control to stmmac driver core.
To support reset control deferred probing, this patch changes the driver
probe function to return the actual error, instead of just -EINVAL.

Subject: [PATCH] net: stmmac: Allocate and pass soc/board specific data to
callbacks
The current .init and .exit callbacks requires access to driver
private data structures. This is not a good seperation and abstraction.
Instead, we add a new .setup callback for allocating private data, and
pass the returned pointer to the other callbacks.

address
The snps,phy-addr device tree property is non-standard, and should be
removed in favor of proper phy node support. Remove it from the binding
documents and warn if the property is still used.
Most PHYs respond to address 0, but a few don't, so auto-detect PHY
address by default, to make up for the lack of explicit address selection.

Subject: [PATCH] net: stmmac: Use driver data and callbacks tied with
compatible strings
The stmmac driver core allows passing feature flags and callbacks via
platform data. Add a similar stmmac_of_data to pass flags and callbacks

layers for different SoCs.

Subject: [PATCH] net: stmmac: sunxi platform extensions for GMAC in Allwinner
A20 SoC's
The Allwinner A20 has an ethernet controller that seems to be
an early version of Synopsys DesignWare MAC 10/100/1000 Universal,
which is supported by the stmmac driver.
Allwinner's GMAC requires setting additional registers in the SoC's
clock control unit.
The exact version of the DWMAC IP that Allwinner uses is unknown,
thus the exact feature set is unknown.

+* Allwinner GMAC ethernet controller
+
+This device is a platform glue layer for stmmac.
+Please see stmmac.txt for the other unchanged properties.
+
+Required properties:
+ - compatible: Should be "allwinner,sun7i-a20-gmac"
+ - clocks: Should contain the GMAC main clock, and tx clock
+ The tx clock type should be "allwinner,sun7i-a20-gmac-clk"
+ - clock-names: Should contain the clock names "stmmaceth",
+ and "allwinner_gmac_tx"
+
+Optional properties:
+- phy-supply: phandle to a regulator if the PHY needs one
+
+Examples:
+
+ gmac: ethernet@01c50000 {
+ compatible = "allwinner,sun7i-a20-gmac";
+ reg = <0x01c50000 0x10000>,
+ <0x01c20164 0x4>;
+ interrupts = <0 85 1>;
+ interrupt-names = "macirq";
+ clocks = <&ahb_gates 49>, <&gmac_tx>;

In various cases errors may be expected, ie probe-deferral or a call to
phy_get from a driver where the use of a phy is optional.
Rather then adding all sort of complicated checks for this, and/or adding
special functions like devm_phy_get_optional, simply don't log an error,
and let deciding if get_phy returning an error really should result in a
dev_err up to the caller.

Subject: [PATCH] phy-core: Don't allow building phy-core as a module
include/phy/phy.h has stub code in there for when building without the
phy-core enabled. This is useful for generic drivers such as ahci-platform,
ehci-platoform and ohci-platform which have support for driving an optional
phy passed to them through the devicetree.
Since on some boards this phy functionality is not needed, being able to
disable the phy subsystem without needing a lot of #ifdef magic in the
driver using it is quite useful.
However this breaks when the module using the phy subsystem is build-in and
the phy-core is not, which leads to the build failing with missing symbol
errors in the linking stage of the zImage.
Which leads to gems such as this being added to the Kconfig for achi_platform:
depends on GENERIC_PHY || !GENERIC_PHY
Rather then duplicating this code in a lot of places using the phy-core,
I believe it is better to simply not allow the phy-core to be built as a
module. The phy core is quite small and has no external dependencies, so
always building it in when enabling it should not be an issue.

Subject: [PATCH] libahci: Allow drivers to override start_engine
Allwinner A10 and A20 ARM SoCs have an AHCI sata controller which needs a
special register to be poked before starting the DMA engine.
This register gets reset on an ahci_stop_engine call, so there is no other
place then ahci_start_engine where this poking can be done.
This commit allows drivers to override ahci_start_engine behavior for use by
the Allwinner AHCI driver (and potentially other drivers in the future).

From 98601575da5276173233dd575bdd61cccdeb861a Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>
Date: Mon, 20 Jan 2014 14:58:04 +0100
Subject: [PATCH] ahci-platform: "Library-ise" ahci_probe functionality
ahci_probe consists of 3 steps:
1) Get resources (get mmio, clks, regulator)
2) Enable resources, handled by ahci_platform_enable_resouces
3) The more or less standard ahci-host controller init sequence
This commit refactors step 1 and 3 into separate functions, so the platform
drivers for AHCI implementations which need a specific order in step 2,
and / or need to do some custom register poking at some time, can re-use
ahci-platform.c code without needing to copy and paste it.
Note that ahci_platform_init_host's prototype takes the 3 non function
members of ahci_platform_data as arguments, the idea is that drivers using
the new exported utility functions will not use ahci_platform_data at all,
and hopefully in the future ahci_platform_data can go away entirely.

Subject: [PATCH] libahci: Add a pre ahci_start_engine hook
Allwinner A10 and A20 ARM SoCs have an AHCI sata controller which need a
special register to be poked before starting the DMA engine.
This register gets reset on an ahci_stop_engine call, so there is no other
place then ahci_start_engine where this poking can be done.
This commit adds a pre ahci_start_engine hook for use by the Allwinner AHCI
driver (and potentially other drivers in the future).

Subject: [PATCH] ARM: sunxi: Add support for Allwinner SUNXi SoCs sata to
ahci_platform
This patch adds support for the ahci sata controler found on Allwinner A10
and A20 SoCs to the ahci_platform driver.
Orignally written by Olliver Schinagl using the approach of having a platform
device which probe method creates a new child platform device which gets
driven by ahci_platform.c, as done by ahci_imx.c .
Refactored by Hans de Goede to add most of the non sunxi specific functionality
to ahci_platform.c and use a platform_data pointer from of_device_id for the
sunxi specific bits.

Subject: [PATCH] ARM: sunxi: Add ahci-sunxi driver for the Allwinner SUNXi
SoCs sata
This patch adds support for the ahci sata controler found on Allwinner A10
and A20 SoCs.
Orignally written by Olliver Schinagl using the approach of having a platform
device which probe method creates a new child platform device which gets
driven by ahci_platform.c, as done by ahci_imx.c .
Given that almost all functionality already is shared through libahci /
ata-core, and that ahci_platform.c cannot cleanly handle somewhat more complex
platform specific ahci cases, such as the sunxi case, it was refactored into
a stand-alone platform driver by Hans de Goede.

Subject: [PATCH] ata: ahci_platform: runtime resume the device before use
On OMAP platforms the device needs to be runtime resumed before
it can be accessed. The OMAP HWMOD framework takes care of
enabling the module and its resources based on the
device's runtime PM state.
In this patch we runtime resume during .probe() and runtime suspend
after .remove().
We also update the runtime PM state during .resume().

Subject: [PATCH] sunxi-mmc: Simplify clk delay setting
clk_sunxi_mmc_phase_control() does its own locking, so there is no need to
lock at the host. Without the locking having a separate sunxi_mmc_set_clk_dly()
makes no sense, so simply call clk_sunxi_mmc_phase_control() directly.

Subject: [PATCH] sunxi-mmc: Don't set mmc clk in low power mode
The android driver uses an io-flag to descern whether a controller is
hooked up to a sdcard slot, or to an onboard sdio dev. And for sdcard slots
it sets the clock in a low-power mode.
This is causing transmission errors when talking to the sdio-wifi on the
cubietruck, and this may be the cause of problems with some type sdcards
too. This patch fixes things by simply never setting the clk in low power
mode.

UHS requires a regulator to set the signaling voltage, as well as special
code to handle the signal voltage switching. We've never added the code
for this from the android driver to the upstream driver, so stop claiming
support for this.

Subject: [PATCH] sunxi-mmc: Or in caps, rather then overriding them
Now that we use mmc_of_parse() there are already some caps set by mmc_of_parse,
so or in our driver caps, rather then using an assignment. This fixes the
card running only in 1 bit mode instead of 4 bit mode problem we've had
since we switched to using mmc_of_parse().

mmc_of_parse registers an irq handler for the gpio pins for cd, this irq
handler will reference host->ops, so don't call mmc_of_parse until we're
done setting everything up.

Subject: [PATCH] sunxi-mmc: fixup: revert "add host initialization for when
the sdio irq is enabled"
This is not necessary since when the host is not initialized at this point
yet the irq line from the mmc controller is not enabled, so writing the
host controller interrupt mask cannot cause interrupts at this point.
More over doing this is wrong, as it leads to unbalanced calling of
clk_prepare_enable and regulator_power_on.

Subject: [PATCH] ARM: sun4i: dt: Fixup mmc bindings
1) Now that we're no longer overriding the caps set by mmc_of_parse we need
to set cd-inverted for our card detection to work.
2) Now that we no longer claim UHS modes support we will never use any DDR
modes, so drive-strength 2 is enough for the mmc data pins.

3) mmc1 on the A13 is not routed to any pins, and thus unusable, remove it
from the dtsi
