This series adds :
_ update existing sdhci driver to use reset framework
_ add usb phy driver
_ add ehci support
_ add ohci support
_ add xhci support
_ add fastboot support
With all this feature enable, it's now possible to
_ boot on usb mass storage device
_ boot from kernel image and dtb previously loaded using tftp
_ update mmc partiton using fastboot
v3: _ remove reset driver (already applied on u-boot-dm tree by Simon
Glass)
_ patch 4: add new USB PHY uclass requested by Simon Glass
_ patch 5: convert STi usb phy driver to new USB PHY uclass
_ patch 6/7: update echi/ohci drivers to use USB PHY uclass
_ patch 8/9: rework xhci-sti.c and dwc3-sti.c. Previously, xhci-sti driver binded
dwc3-sti (STi glue driver) which was not correct. Now we respect the device
tree hierarchy, ie the STi dwc3 glue driver is first probed, then bind the
xhci-sti driver.
v2: _ add Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com> in patches 2,3 and 4
_ fix remarks done by Marek Vasut :
_ patch 5 : replace bitfield_replace() by clrsetbits_le32()
_ patch 6 : update error messages and add remove callback
_ patch 8 : put board specific defines in a separate patch
_ patch 7: use setbits_le32() instead of read, modify, write
sequence and add missing parenthesis
_ squash previous patches 7,9,11,12,14,16,17,18,19,20 and 21
in patch 14

This to prepare to use the reset framework.

+ST STiH407 USB PHY controller
+
+This file documents the dt bindings for the usb picoPHY driver which is the PHY for both USB2 and USB3
+host controllers (when controlling usb2/1.1 devices) available on STiH407 SoC family from STMicroelectronics.
+
+Required properties:
+- compatible : should be "st,stih407-usb2-phy"
+- st,syscfg : phandle of sysconfig bank plus integer array containing phyparam and phyctrl register offsets
+- resets : list of phandle and reset specifier pairs. There should be two entries, one
+ for the whole phy and one for the port
+- reset-names : list of reset signal names. Should be "global" and "port"
+See: Documentation/devicetree/bindings/reset/st,sti-powerdown.txt
+See: Documentation/devicetree/bindings/reset/reset.txt
+
+Example:
+
+usb2_picophy0: usbpicophy at f8 {
+ compatible = "st,stih407-usb2-phy";
+ #phy-cells = <0>;
+ st,syscfg = <&syscfg_core 0x100 0xf4>;
+ resets = <&softreset STIH407_PICOPHY_SOFTRESET>,
+ <&picophyreset STIH407_PICOPHY0_RESET>;

Add support for on-chip DWC3 controller available
on STMicrolectronics STiH407 family SoCs.
On B2260 board, the type AB USB connector is managed
by a DWC3 IP. As USB3 signals are not wired, only USB2
is supported.
Signed-off-by: Patrice Chotard <patrice.chotard@st.com>

v3: _ update to use the new USB PHY uclass
_ previously, xhci-sti driver binded dwc3-sti (STi glue driver) which was not correct.
Now we respect the device tree hierarchy, ie the STi dwc3 glue driver is first probed,
then bind the xhci-sti driver.

This patch adds the ST glue logic to manage the DWC3 HC
on STiH407 SoC family. It configures the internal glue
logic and syscfg registers.
Part of this code been extracted from kernel.org driver
(drivers/usb/dwc3/dwc3-st.c)
Signed-off-by: Patrice Chotard <patrice.chotard@st.com>

v3: _ rename dwc3-sti.c to dwc3-sti-glue.c
_ respect device tree hierarchy, this driver is now responsible
for xhci-sti binding (done in sti_dwc3_glue_bind())
v2: _ use setbits_le32() instead of read, modify, write sequence
_ add missing parenthesis

+ST DWC3 glue logic
+
+This file documents the parameters for the dwc3-st driver.
+This driver controls the glue logic used to configure the dwc3 core on
+STiH407 based platforms.
+
+Required properties:
+ - compatible : must be "st,stih407-dwc3"
+ - reg : glue logic base address and USB syscfg ctrl register offset
+ - reg-names : should be "reg-glue" and "syscfg-reg"
+ - st,syscon : should be phandle to system configuration node which
+ encompasses the glue registers
+ - resets : list of phandle and reset specifier pairs. There should be two entries, one
+ for the powerdown and softreset lines of the usb3 IP
+ - reset-names : list of reset signal names. Names should be "powerdown" and "softreset"
+
+ - #address-cells, #size-cells : should be '1' if the device has sub-nodes
+ with 'reg' property
+
+ - pinctl-names : A pinctrl state named "default" must be defined
+
+ - pinctrl-0 : Pin control group
+
+ - ranges : allows valid 1:1 translation between child's address space and
+ parent's address space
+
+Sub-nodes:
+The dwc3 core should be added as subnode to ST DWC3 glue as shown in the
+example below.
+
+NB: The dr_mode property is NOT optional for this driver, as the default value
+is "otg", which isn't supported by this SoC. Valid dr_mode values for dwc3-st are
+either "host" or "device".
+
+Example:
+
+st_dwc3: dwc3 at 8f94000 {
+ status = "disabled";
+ compatible = "st,stih407-dwc3";
+ reg = <0x08f94000 0x1000>, <0x110 0x4>;
+ reg-names = "reg-glue", "syscfg-reg";
+ st,syscfg = <&syscfg_core>;
+ resets = <&powerdown STIH407_USB3_POWERDOWN>,
+ <&softreset STIH407_MIPHY2_SOFTRESET>;
+ reset-names = "powerdown", "softreset";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_usb3>;
+ ranges;
+
+ dwc3: dwc3 at 9900000 {
+ compatible = "snps,dwc3";
+ reg = <0x09900000 0x100000>;
+ interrupts = <GIC_SPI 155 IRQ_TYPE_NONE>;
+ dr_mode = "host";
+ phy-names = "usb2-phy", "usb3-phy";
+ phys = <&usb2_picophy2>, <&phy_port2 PHY_TYPE_USB3>;
+ };
+};

I think nobody.
Vipin Kumar <vipin.kumar@st.com> was ST custodian for STMicroelectronics
SPEAR architecture.
I tried to contact him, got no response, and not sure he was still
employed by ST.

Can you please take a look at u-boot-dm/next in generic_phy.h? Does
that uclass do what you need or is there something specific about the
USB PHY?

OK. I wonder if Tom might apply these, although I have a comment on
the PHY patch.

Few Month ago I had the next answer for vipin when I ask about ST branch :
Hello Patrick,
I used to manage u-boot on spear for the time I was at ST. As you rightly pointed,
this branch is unused and can be used by an ST employee for other projects
However, you would still have to ping Wolfgang denk to pass the ssh key
Regards
Vipin
So the ST branch is today orphan, without custodians.
In the near future ST will propose someone to take back this role for new ST projects (new chip but no for spear family).
Do you think is already time to propose a new name ?
Regards,
Patrick

> Do you think is already time to propose a new name ?
Few weeks ago, i asked if a dedicated STi U-Boot git tree was needed for
my upstream activities about STiH410-B2260, Tom didn't required it
(http://u-boot.10912.n7.nabble.com/STi-U-boot-git-tree-request-td283565.html).
Tom, Simon, tell us about your favorite choice. At STMicroelectronics,
we can propose someone for current ST platforms (STi and STM32) and for
newt projects.

This generic_phy looks ok for my needs, i will rework this series and
resubmit a v4 soon.

Well, As I was asking in private, there's no overlap between STM32 and
STi, so I don't think we need a "st" tree at this time. Thanks!

FYI a new v4 is available following remarks from Simon Glass in order to
use the new PHY uclass available on dm-next branch
