[PATCH v4 0/7] arm64: dts: exynos: Add E850-96 board support

[PATCH v4 0/7] arm64: dts: exynos: Add E850-96 board support

[Sam Protsenko]

WinLink's E850-96 is a dev board based on Exynos850 SoC [1]. The board's
design follows 96boards specifications, hence it's compatible with
96boards mezzanines [2].

This patch series adds the initial support for E850-96 board and
Exynos850 SoC, along with corresponding bindings. Only basic platform
components are enabled at the moment (like serial, I2C, eMMC, RTC, WDT,
clock driver, etc). Right now with this patch series it's possible to
run the kernel with BusyBox rootfs as a RAM disk. More features are
coming soon.

Changes in v4:
  - Removed slew_rate pin nodes
  - Moved rtcclk clock to board dts file

Changes in v3:
  - Ordered the pinctrl_alive phandle alphabetically (patch 7/7)
  - No other changes in v3

Changes in v2:
  - Rebased on krzk/linux.git (for-next), to account for Exynos7885
    changes
  - Added missing and new tags (R-b and Ack)
  - Addressed all comments for v1

[PATCH v4 1/7] dt-bindings: clock: exynos850: Add bindings for Exynos850 sysreg clocks

[Sam Protsenko]

System Register is used to configure system behavior, like USI protocol,
etc. SYSREG clocks should be provided to corresponding syscon nodes, to
make it possible to modify SYSREG registers.

While at it, add also missing PMU and GPIO clocks, which looks necessary
and might be needed for corresponding Exynos850 features soon.

Sam,

The clock is used in the DTSI, so since this was applied, there are only
two choices now:
1. wait for next cycle with DTSI and DTS,
2. Resubmit with replacing the newly added clocks in DTSI/DTS with
numbers and a TODO note.

Best regards,
Krzysztof

But why? I thought because Sylwester applied my clock patches, those
will get into v5.17, and so DTSI/DTS might rely on those clocks? If I
get it wrong, please let me know why, and I'll go with item (2) you
suggested.

If I apply the DTSI+DTS, all my builds will start failing. The
linux-next (since Sylwester's tree is included) should build fine, but
my tree won't be buildable anymore. Then arm-soc pulls my tree and gets
said because it does not build. Later, Linus will be unhappy if he pulls
arm-soc (thus mine) before clock tree.

Other solution, instead of using raw numbers, is to copy-paste the clock
macros you use directly in DTSI and do not include the clock header.
This actually might be cleaner choice - changes will be limited to one
place in DTSI.

Best regards,
Krzysztof

[PATCH v4 2/7] clk: samsung: exynos850: Add missing sysreg clocks

[Sam Protsenko]

System Register is used to configure system behavior, like USI protocol,
etc. SYSREG clocks should be provided to corresponding syscon nodes, to
make it possible to modify SYSREG registers.

While at it, add also missing PMU and GPIO clocks, which looks necessary
and might be needed for corresponding Exynos850 features soon.

[PATCH v4 2/7] clk: samsung: exynos850: Add missing sysreg clocks

[Sam Protsenko]

System Register is used to configure system behavior, like USI protocol,
etc. SYSREG clocks should be provided to corresponding syscon nodes, to
make it possible to modify SYSREG registers.

While at it, add also missing PMU and GPIO clocks, which looks necessary
and might be needed for corresponding Exynos850 features soon.

[PATCH v4 6/7] arm64: dts: exynos: Add initial Exynos850 SoC support

[Sam Protsenko]

Samsung Exynos850 is ARMv8-based mobile-oriented SoC. This patch adds
initial SoC support. It's not comprehensive yet, some more devices will
be added later. Right now only crucial system components and most needed
platform devices are defined.

Crucial features (needed to boot Linux up to shell with serial console):

  * Octa cores (Cortex-A55), supporting PSCI v1.0
  * ARM architected timer (armv8-timer)
  * Interrupt controller (GIC-400)
  * Pinctrl nodes for GPIO
  * Serial node

Basic platform features:

  * Clock controller CMUs
  * OSCCLK clock
  * MCT timer
  * ARM PMU (Performance Monitor Unit)
  * Chip-id
  * RTC
  * Reset
  * Watchdog timers
  * eMMC
  * I2C
  * HSI2C
  * USI

All those features were already enabled and tested on E850-96 board with
minimal BusyBox rootfs.

Changes in v4:
  - Removed fast slew rate nodes from pinctrl dtsi
  - Added R-b tag by Chanho Park
  - Moved "rtcclk" clock to board dts file
    - Specified "rtc_src" clock for rtc node in board dts file
    - Specified "rtcclk" clock for cmu_hsi node in board dts file

Changes in v3:
  - (none)

Changes in v2:
  - Merged spi*_cs_func_pins nodes (Chip Select pin) into spi*_pins
    nodes
  - Removed spi*_cs_pins nodes (GPIO configuration for SPI CS pins)
  - Sorted pinctrl_peri "pins" nodes  by name
  - Removed USI aliases
  - Added TODO comment for RTC clock (needs to be implemented in PMIC)
  - Sorted cmu nodes by unit address
  - Sorted pinctrl nodes by unit address

[PATCH v4 6/7] arm64: dts: exynos: Add initial Exynos850 SoC support

[Sam Protsenko]

Samsung Exynos850 is ARMv8-based mobile-oriented SoC. This patch adds
initial SoC support. It's not comprehensive yet, some more devices will
be added later. Right now only crucial system components and most needed
platform devices are defined.

Crucial features (needed to boot Linux up to shell with serial console):

  * Octa cores (Cortex-A55), supporting PSCI v1.0
  * ARM architected timer (armv8-timer)
  * Interrupt controller (GIC-400)
  * Pinctrl nodes for GPIO
  * Serial node

Basic platform features:

  * Clock controller CMUs
  * OSCCLK clock
  * MCT timer
  * ARM PMU (Performance Monitor Unit)
  * Chip-id
  * RTC
  * Reset
  * Watchdog timers
  * eMMC
  * I2C
  * HSI2C
  * USI

All those features were already enabled and tested on E850-96 board with
minimal BusyBox rootfs.

Changes in v4:
  - Removed fast slew rate nodes from pinctrl dtsi
  - Added R-b tag by Chanho Park
  - Moved "rtcclk" clock to board dts file
    - Specified "rtc_src" clock for rtc node in board dts file
    - Specified "rtcclk" clock for cmu_hsi node in board dts file

Changes in v3:
  - (none)

Changes in v2:
  - Merged spi*_cs_func_pins nodes (Chip Select pin) into spi*_pins
    nodes
  - Removed spi*_cs_pins nodes (GPIO configuration for SPI CS pins)
  - Sorted pinctrl_peri "pins" nodes  by name
  - Removed USI aliases
  - Added TODO comment for RTC clock (needs to be implemented in PMIC)
  - Sorted cmu nodes by unit address
  - Sorted pinctrl nodes by unit address

[PATCH v4 7/7] arm64: dts: exynos: Add initial E850-96 board support

[Sam Protsenko]

E850-96 is a 96boards development board manufactured by WinLink. It
incorporates Samsung Exynos850 SoC, and is compatible with 96boards
mezzanine boards [1], as it follows 96boards standards.

This patch adds minimal support for E850-96 board. Next features are
enabled in board dts file and verified with minimal BusyBox rootfs:

 * User buttons
 * LEDs
 * Serial console
 * Watchdog timers
 * RTC
 * eMMC

Changes in v4:
  - Moved "rtcclk" clock to board dts file
    - Specified "rtc_src" clock for rtc node in board dts file
    - Specified "rtcclk" clock for cmu_hsi node in board dts file
  - Improved comment for RAM memory node

Changes in v3:
  - Ordered the pinctrl_alive phandle alphabetically (forgot to do so in
    v2)

Changes in v2:
  - Removed board_id and board_rev properties
  - Removed BOARD_ID and BOARD_REV constants
  - Put dtb in alphabetical order in Makefile
  - Added "color" and "function" properties to LED nodes
  - Sorted all phandle overrides by phandle name
  - Removed 'broken-cd' property in eMMC node
  - Added memory node
