[PATCH 0/1] meson-gxl: improve support for the P212 board

[PATCH 0/1] meson-gxl: improve support for the P212 board

[Martin Blumenstingl]

The P212 board is a reference design and re-used by other boards (similar
to the meson-gxbb-p20x.dtsi which is inherited by the Wetek boards).
Until now only very basic functionality was supported, but most of the
interesting things (wifi, SD, eMMC, IR, etc.) are not enabled yet - which
changes with this patch.

I have tested this with a Khadas VIM board (patch for this will follow)
as I don't have a P212 board itself. Thus it would be nice if someone
could test it on an actual P212 board.

Please also specifically review the copyright statements in
meson-gxl-s905x-p212.dtsi - I want to make sure I didn't mess anything
up there.

[PATCH 1/1] ARM64: dts: meson-gxl: improve support for the P212 reference design

[Martin Blumenstingl]

The Amlogic P212 reference design is used by other devices as well, such
as (for example) the Khadas VIM boards. Thus this patch adds and moves
all common entries from meson-gxl-s905x-p212.dts to a new, separate
meson-gxl-s905x-p212.dtsi (which can be re-used on boards such as the
Khadas VIM).
Support for all boards based on the P212 reference design includes:
- enabling IR support
- enabling the SAR ADC (SARADC_CH1 is connected to a resistor which
  indicates the hardware revision, a similar design is found on the
  Khadas VIM boards)
- all MMC controllers (which means that SDIO wifi, the SD card and the
  eMMC are now supported)
- pwm_ef as dependency for the SDIO wifi module
- uart_A which is connected to the bluetooth module (the bluetooth
  module itself is not enabled yet due to missing devicetree bindings
  for the Broadcom serial bluetooth devices)
- uart_AO is moved to the .dtsi (as all known devices use it as their
  boot-console)

Specific to the P212 board:
- this also enables the CVBS connector (which is not available on the
  Khadas VIM boards for example)

[PATCH 1/1] ARM64: dts: meson-gxl: improve support for the P212 reference design

[Martin Blumenstingl]

The Amlogic P212 reference design is used by other devices as well, such
as (for example) the Khadas VIM boards. Thus this patch adds and moves
all common entries from meson-gxl-s905x-p212.dts to a new, separate
meson-gxl-s905x-p212.dtsi (which can be re-used on boards such as the
Khadas VIM).
Support for all boards based on the P212 reference design includes:
- enabling IR support
- enabling the SAR ADC (SARADC_CH1 is connected to a resistor which
  indicates the hardware revision, a similar design is found on the
  Khadas VIM boards)
- all MMC controllers (which means that SDIO wifi, the SD card and the
  eMMC are now supported)
- pwm_ef as dependency for the SDIO wifi module
- uart_A which is connected to the bluetooth module (the bluetooth
  module itself is not enabled yet due to missing devicetree bindings
  for the Broadcom serial bluetooth devices)
- uart_AO is moved to the .dtsi (as all known devices use it as their
  boot-console)

Specific to the P212 board:
- this also enables the CVBS connector (which is not available on the
  Khadas VIM boards for example)

[PATCH 1/1] ARM64: dts: meson-gxl: improve support for the P212 reference design

[Martin Blumenstingl]

The Amlogic P212 reference design is used by other devices as well, such
as (for example) the Khadas VIM boards. Thus this patch adds and moves
all common entries from meson-gxl-s905x-p212.dts to a new, separate
meson-gxl-s905x-p212.dtsi (which can be re-used on boards such as the
Khadas VIM).
Support for all boards based on the P212 reference design includes:
- enabling IR support
- enabling the SAR ADC (SARADC_CH1 is connected to a resistor which
  indicates the hardware revision, a similar design is found on the
  Khadas VIM boards)
- all MMC controllers (which means that SDIO wifi, the SD card and the
  eMMC are now supported)
- pwm_ef as dependency for the SDIO wifi module
- uart_A which is connected to the bluetooth module (the bluetooth
  module itself is not enabled yet due to missing devicetree bindings
  for the Broadcom serial bluetooth devices)
- uart_AO is moved to the .dtsi (as all known devices use it as their
  boot-console)

Specific to the P212 board:
- this also enables the CVBS connector (which is not available on the
  Khadas VIM boards for example)

[PATCH v2 0/1] meson-gxl: improve support for the P212 board

[Martin Blumenstingl]

The P212 board is a reference design and re-used by other boards (similar
to the meson-gxbb-p20x.dtsi which is inherited by the Wetek boards).
Until now only very basic functionality was supported, but most of the
interesting things (wifi, SD, eMMC, IR, etc.) are not enabled yet - which
changes with this patch.

Neil Armstrong kindly took take the information he had from Amlogic for
the P212 board itself and built a list of supported features and
differences with the Khadas VIM boards (which are based on the P212
reference design). This patch is a result of that.

I have tested this with a Khadas VIM board (patch for this will follow)
as I don't have a P212 board itself. Thus it would be nice if someone
could test it on an actual P212 board.

Please also specifically review the copyright statements in
meson-gxl-s905x-p212.dtsi - I want to make sure I didn't mess anything
up there.


Changes since v1:
- update the cover letter to indicate where the information about the
  P212 reference design came from
- use SPDX tags instead of including the full license text
- removed the brcmf sub-node of the sd_emmc_a node as the P212 reference
  design uses a Realtek based wifi chip (and updated the commit
  description accordingly)
- included Neil's Tested-By

[PATCH v2 1/1] ARM64: dts: meson-gxl: improve support for the P212 reference design

[Martin Blumenstingl]

The Amlogic P212 reference design is used by other devices as well, such
as (for example) the Khadas VIM boards. Thus this patch adds and moves
all common entries from meson-gxl-s905x-p212.dts to a new, separate
meson-gxl-s905x-p212.dtsi (which can be re-used on boards such as the
Khadas VIM).
Support for all boards based on the P212 reference design includes:
- enabling IR support
- enabling the SAR ADC (SARADC_CH1 is connected to a resistor which
  indicates the hardware revision, a similar design is found on the
  Khadas VIM boards)
- all MMC controllers (which means that SDIO wifi, the SD card and the
  eMMC are now supported)
- pwm_ef as dependency for the SDIO wifi modules
- uart_A which is connected to the bluetooth module (the bluetooth
  module itself is not enabled yet due to missing devicetree bindings
  for the Broadcom serial bluetooth devices)
- uart_AO is moved to the .dtsi (as all known devices use it as their
  boot-console)

Specific to the P212 board:
- this also enables the CVBS connector (which is not available on the
  Khadas VIM boards for example)
- Realtek based SDIO wifi (instead of Broadcom which most other devices
  use)

[PATCH v2 1/1] ARM64: dts: meson-gxl: improve support for the P212 reference design

[Martin Blumenstingl]

The Amlogic P212 reference design is used by other devices as well, such
as (for example) the Khadas VIM boards. Thus this patch adds and moves
all common entries from meson-gxl-s905x-p212.dts to a new, separate
meson-gxl-s905x-p212.dtsi (which can be re-used on boards such as the
Khadas VIM).
Support for all boards based on the P212 reference design includes:
- enabling IR support
- enabling the SAR ADC (SARADC_CH1 is connected to a resistor which
  indicates the hardware revision, a similar design is found on the
  Khadas VIM boards)
- all MMC controllers (which means that SDIO wifi, the SD card and the

- pwm_ef as dependency for the SDIO wifi modules
- uart_A which is connected to the bluetooth module (the bluetooth
  module itself is not enabled yet due to missing devicetree bindings
  for the Broadcom serial bluetooth devices)
- uart_AO is moved to the .dtsi (as all known devices use it as their
  boot-console)

Specific to the P212 board:
- this also enables the CVBS connector (which is not available on the
  Khadas VIM boards for example)
- Realtek based SDIO wifi (instead of Broadcom which most other devices

[PATCH v2 1/1] ARM64: dts: meson-gxl: improve support for the P212 reference design

[Martin Blumenstingl]

The Amlogic P212 reference design is used by other devices as well, such
as (for example) the Khadas VIM boards. Thus this patch adds and moves
all common entries from meson-gxl-s905x-p212.dts to a new, separate
meson-gxl-s905x-p212.dtsi (which can be re-used on boards such as the
Khadas VIM).
Support for all boards based on the P212 reference design includes:
- enabling IR support
- enabling the SAR ADC (SARADC_CH1 is connected to a resistor which
  indicates the hardware revision, a similar design is found on the
  Khadas VIM boards)
- all MMC controllers (which means that SDIO wifi, the SD card and the
  eMMC are now supported)
- pwm_ef as dependency for the SDIO wifi modules
- uart_A which is connected to the bluetooth module (the bluetooth
  module itself is not enabled yet due to missing devicetree bindings
  for the Broadcom serial bluetooth devices)
- uart_AO is moved to the .dtsi (as all known devices use it as their
  boot-console)

Specific to the P212 board:
- this also enables the CVBS connector (which is not available on the
  Khadas VIM boards for example)
- Realtek based SDIO wifi (instead of Broadcom which most other devices
  use)

I also gave this a spin on P212 board and it's working well.

Applied to v4.12/dt64
