[PATCH v3 00/27] ARM: dts: exynos: Add initial support for Odroid XU

[Krzysztof Kozlowski]

Hi,

Patchset adds necessary clocks, reorganizes existing stuff and finally
adds Odroid XU support.


Changes since v2
================
1. Got global-ack from Stephen for the clock changes. I think merging
   everything through arm-soc might be the easiest but:
   a. In such case I will prepare a tag with clock changes,
   b. Anyway I will wait for response from Sylwester and Tomasz.
2. Applied comments from Javier and added his Reviewed-by.
3. Patch 22: added ack from Rob.
4. Minor improvements in existing patches.
5. Five new patches at the end: 23-27 (not reviewed yet).
   Some of them could be squashed with existing ones but existing
   changes got reviews. Although the final Odroid XU DTS works fine but
   in general this is still work-in-progress so I suspect it will grow.
   I am releasing it early following Linux concept. :)

Patchset is available at my private repo @github:
https://github.com/krzk/linux.git for-next/odroid-xu-v3

(previous version is in for-next/odroid-xu-v2 branch, if someone would
like to compare them)


Changes since v1
================
1. A lot of new patches.
2. Removed some TODO notes (eMMC 4.5 so no RCLK pin).
3. New clocks, more reorganization.
4. New common DTSI: exynos54xx.dtsi. I know, it is getting more
   and more complicated but this might help removing duplications
   and keeping everything under control.



Merging strategy
================
Complicated! The clock dt-bindings and driver changes can go to clock
tree. However there are three DTS patches in the middle.
a. This has to go in before adding "fin_pll_new" to clock driver:
   - [PATCH v2 03/22] ARM: dts: exynos: Add fin_pll node for clock driver

b. This should go in before renaming "fin_pll_new" back to original name:
   - [PATCH v2 05/22] ARM: dts: exynos: Switch MCT node to a new fin_pll clock
   - [PATCH v2 06/22] ARM: dts: exynos: Remove old fixed-clock provider on SMDK5410

The order of patches in the patchset is really how it should go in
to reduce any bisectability glitches.


Best regards,
Krzysztof

[PATCH v3 03/27] ARM: dts: exynos: Add fin_pll node for clock driver

[Krzysztof Kozlowski]

For consistency between Exynos5410 and Exynos542x/5800 switch to similar
way of defining fin_pll/oscclk. Add a node early, before implementing
this in driver to preserve bisectability.

[PATCH v3 04/27] clk: samsung: exynos5410: Provide fin_pll external fixed clock

[Krzysztof Kozlowski]

Just like clock driver for Exynos542x/5800, provide the fixed clock here
so the clock bindings and their consumers would be consistent and
similar.

However a clock named "fin_pll" is already provided by generic
fixed-clock and it is both referenced in the clock driver (by name) and
in DT (by phandle). To make the transition smooth, first introduce the
new external fixed clock here under temporary, different name and switch
internal users to it.

[PATCH v3 08/27] clk: samsung: exynos5410: Add serial3, USB and PWM clocks

[Krzysztof Kozlowski]

Just like other Exynos5 family SoCs, this one has four UARTs. Add
missing UART3 clocks to the Exynos5410 clock driver.

Add clocks for USB and PWM.

[PATCH v3 13/27] ARM: dts: exynos: Move common nodes to exynos5.dtsi

[Krzysztof Kozlowski]

Exynos5420 and Exynos5250 share some nodes: the PWM, syscon
(sysreg_system_controller) and first four I2C controllers. Move them to
parent DTSI to avoid duplication.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

Important changes since v2:
1. Move also i2c[0123] to exynos5.dtsi.

The i2c-arbitrator node in exynos5250-snow-common used absolute path to

depth of the other node may be changed (like moving it under 'soc'
node).

[Krzysztof Kozlowski]

The exynos5.dtsi is used for common nodes shared between Exynos5250 and
Exynos542x. Since Exynos5410 is very similar to Exynos5420 it can
include the common file as well to remove duplication and make
everything more consistent.

[PATCH v3 18/27] ARM: dts: exynos: Enable UART3 on Exynos5410

[Krzysztof Kozlowski]

Just like other Exynos5 family SoCs, this one has four UARTs. Configure
clocks for UART3 and enable it.

[PATCH v3 19/27] ARM: dts: exynos: MCT is not an interrupt controller and extend length of iomap

[Krzysztof Kozlowski]

Multi-Core Timer generates interrupts but it is not really an interrupt
controller so remove the "interrupt-controller" and "interrupt-cells"
properties. Additionally extend the length of mapped memory to cover all
registers (last SFR is at 0x0A40).

[PATCH v3 20/27] ARM: dts: exynos: Move common Exynos5410/542x/5800 nodes to new DTSI

[Krzysztof Kozlowski]

The Exynos5410/542x/5800 are very similar designs. Create a new
DTSI with common nodes to remove DTS duplication. Although currently
only MCT and SysRAM are shared but in future more nodes will be added to
the common file.

The patch should not have functional impact.

[PATCH v3 21/27] ARM: dts: exynos: Add USB to Exynos5410

[Krzysztof Kozlowski]

Move USB 3.0 DWC and 2.0 EHCI/OHCI nodes from exynos5420.dtsi to
exynos54xx.dtsi common for entire family. For Exynos542x/5800 this
should not have functional impact but for Exynos5410 this effectively
adds USB support.

[PATCH v3 22/27] ARM: dts: exynos: Add initial support for Odroid XU board

[Krzysztof Kozlowski]

The Hardkernel's Odroid XU board was first design with big.LITTLE SoC
from Samsung: the Exynos5410. Comparing the board to more popular now
Odroid XU3, the differences are:
1. Exynos5410 instead of 5422,
2. MIPI DSI LCD connector,
3. Main PMIC: Maxim 77802 instead of S2MPS11,
4. USB3503+LAN9730 instead of integrated LAN9514,
5. eMMC 4.5 instead of eMMC 5.0,

This patch adds initial support for the XU board with working basic
functions, eMMC/SD and USB (including attached ethernet adapter).

[PATCH v3 23/27] dt-bindings: clock: Add I2C, HSI2C and RTC clock IDs to Exynos5410

[Krzysztof Kozlowski]

Add IDs for I2C, USI (HSI2C) and RTC clocks to Exynos5410. Use the same
number as for Exynos5420 just in case in future these drivers were
merged.

[PATCH v3 26/27] ARM: dts: exynos: Add I2C, PWM and UART pinctrl to Exynos5410

[Krzysztof Kozlowski]

Add pincontrol groups for HSI2C (USI), I2C, PWM and UART to Exynos5410.
This allows configuring these pins to specific functions.

[PATCH v3 27/27] ARM: dts: exynos: Add RTC and I2C to Exynos5410

[Krzysztof Kozlowski]

Configure Exynos5410-specific properties of RTC, I2C and HSI2C nodes.
This still does not enable them on the board level though.

I don't think these comments are needed. For each DTS, there are usually a lot of
nodes defined in higher levels of the DT hierarchy but isn't common to mention it.

Specially since the mentioned nodes are referenced here by their labels so it is
implicit that are defined in one of the included DTSI (or dtc will fail to build).

The actual change looks good to me though:

Okay, if it does not make sense to you then I'll remove them.

I have tested this branch on both an Exynos5422 Odroid XU4 board and an
Exynos5800 Peach Pi Chromebook. All the peripherals are working correctly.

So for all patches affecting Exynos54xx/5800 (9,12,13,14,16,19,20,21,25):

Since I have one of these gathering dust on my desk, it's really cool to 
see this series, thanks!

I've successfully booted that branch to a filesystem on SD card, but USB 
clearly isn't quite right - the USB 2.0 hub is powered up, but only the 
bottom right port will actually enumerate devices; the ethernet is 
nowhere to be seen. However, if I drop into the bootloader and do a "usb 
start" beforehand, it all keeps working into the kernel. As for the USB 
3.0, though, the ports report over-current conditions shortly after the 
XHCI probe despite having nothing plugged in :(
