v5 cover ARM: imx: add imx7ulp support

The i.MX 7ULP family of processors represents NXP?s latest achievement in ultra-low-power processing for use cases demanding long battery life. Targeted towards the growing market of portable devices, the i.MX 7ULP family of processors features NXP's advanced implementation of the Arm? Cortex-A7 core, the Arm Cortex-M4 core, as well as a 3D and 2D Graphics Processing Units (GPUs). The i.MX 7ULP family provides up to 32-bit LPDDR2/LPDDR3 memory interface and a number of other interfaces for connecting peripherals, such as WLAN, Bluetooth, GPS, displays, and camera sensors.

This patch series adds the basic support for imx7ulp. It includes machine level support code and device tree.
Note: it depends on clk driver which is still under review.

v4->v5:
* dts add input clocks for PCC module
* update pad setting due to missing pull up enabled
(formerly auto done by driver generic pinconfg)
* gpio and pinctrl patches were merged by Linus W, so dropped in this series
dt-bindings: gpio: vf610: add optional clocks property
gpio: vf610: add optional clock support
dt-bindings: pinctrl: imx7ulp: back to imx legacy binding for
consistency
pinctrl: fsl: imx7ulp: change to use imx legacy binding

v3->v4:
* add comments about fixed soc version
* add iounmap
v2->v3:
* back to old pinctrl binding according to SoC maintainer's suggestions
* use generic node name
* error checking updated according to Russell's suggestion:
ptr == ERR_PTR(-EPROBE_DEFER)

v1->v2:
* switch to SPDX license
* rebase to latest tree
* pad name update
* add gpio clk support
* minor fix

+The Multi-System Mode Controller (MSMC) is responsible for sequencing
+the MCU into and out of all stop and run power modes. Specifically, it
+monitors events to trigger transitions between power modes while
+controlling the power, clocks, and memories of the MCU to achieve the
+power consumption and functionality of that mode.
+
+The WFI or WFE instruction is used to invoke a Sleep, Deep Sleep or
+Standby modes for either Cortex family. Run, Wait, and Stop are the
+common terms used for the primary operating modes of Kinetis
+microcontrollers.
+
+Required properties:
+- compatible:	Should be "fsl,imx7ulp-smc1".
+- reg:		Specifies base physical address and size of the register sets.
+
+Example:

PATCH v5 3/6 ARM: imx: add initial support for imx7ulp

In reply to A.s. Dong

The i.MX 7ULP family of processors features NXP's advanced implementation of the Arm Cortex-A7 core, the Arm Cortex-M4 core, as well as a 3D and 2D Graphics Processing Units (GPUs).

This patch aims to add an initial support for imx7ulp. Note that we need configure power mode to Partial Stop mode 3 with system/bus clock enabled first as the default enabled STOP mode will gate off system/bus clock when execute WFI in MX7ULP SoC.

And there's still no MXC_CPU_IMX7ULP IDs read from register as ULP has no anatop as before. So we encode one with 0xff in reverse order in case new ones will be in the future.

* add input clocks for PCC module
v3->v4:
* no changes
v2->v3:
* change to generic node names
* remove arch timer due to:
1) arch timer is fixed to 1Mhz which is lower accurate than TPM timer (3Mhz).
2) no firmware progrem CNTFREQ
3) cpuidle driver is still not in tree will may cause system hang
v1->v2:
* update clk part due to binding change
* separate soc.dtsi from board.dts

PATCH v5 5/6 dts: fsl: add imx7ulp evk support

In reply to A.s. Dong

The NXP i.MX 7ULP Evaluation Kit (EVK) provides a platform for rapid evaluation of the i.MX 7ULP, which features NXP's advanced implementation of the Arm Cortex-A7 core, the Arm Cortex-M4 core, as well as a 3D and 2D Graphics Processing Units (GPUs).

The EVK enables HDMI output for simple out-of-the-box to bring up but allows reconfiguration for MIPI displays. The EVK is designed as a System-On-Module(SOM) board that connects to an associated baseboard. The SOM provides 1 GB LPDDR3, 8 MB Quad SPI flash, Micro SD 3.0 card socket, WiFi/ Bluetooth capability, USB 2.0 OTG with Type C connector and an NXP PF1550 power management IC (PMIC). The baseboard provides additional capabilities including a full SD/MMC 3.0 card socket, audio codec, multiple sensors, an HDMI connector, and an alternate MIPI display connector. Additionally, the EVK facilitates software development with the ultimate goal of faster time to market through the support of both Linux OS and AndroidTM rich operating systems, as well as FreeRTOS.

This patch aims to support the preliminary booting up features as follows:
GPIO
LPUART
FEC
SD/MMC

Hi Shawn,

Can you help pick up imx7ulp support series?
The clk patch set is already in clk tree now.
https://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git/log/?h=clk-imx7ulp

Please let me know if you need me to resend.

Regards

Subject: [PATCH V5 0/6] ARM: imx: add imx7ulp support

The i.MX 7ULP family of processors represents NXP’s latest achievement in ultra-low-power processing for use cases demanding long battery life. Targeted towards the growing market of portable devices, the i.MX 7ULP family of processors features NXP's advanced implementation of the Arm® Cortex-A7 core, the Arm Cortex-M4 core, as well as a 3D and 2D Graphics Processing Units (GPUs). The i.MX 7ULP family provides up to 32-bit LPDDR2/LPDDR3 memory interface and a number of other interfaces for connecting peripherals, such as WLAN, Bluetooth, GPS, displays, and camera sensors.

This patch series adds the basic support for imx7ulp. It includes machine level support code and device tree.
Note: it depends on clk driver which is still under review.

v4->v5:
* dts add input clocks for PCC module
* update pad setting due to missing pull up enabled
(formerly auto done by driver generic pinconfg)
* gpio and pinctrl patches were merged by Linus W, so dropped in this series
dt-bindings: gpio: vf610: add optional clocks property
gpio: vf610: add optional clock support
dt-bindings: pinctrl: imx7ulp: back to imx legacy binding for
consistency
pinctrl: fsl: imx7ulp: change to use imx legacy binding

v3->v4:
* add comments about fixed soc version
* add iounmap
v2->v3:
* back to old pinctrl binding according to SoC maintainer's suggestions
* use generic node name
* error checking updated according to Russell's suggestion:

   ptr == ERR_PTR(-EPROBE_DEFER)

v1->v2:
* switch to SPDX license
* rebase to latest tree
* pad name update
* add gpio clk support
* minor fix
