[PATCH v2 0/3] ARM: Initial devicetree for Kobo Aura

[Jonathan Neuschäfer]

This series adds a devicetree for the i.MX507-based Kobo Aura e-book
reader, and fixes a few things in imx50.dtsi along the way.

v1: https://lore.kernel.org/lkml/20190319152421.16179-1-j.neuschaefer@gmx.net/

Changes in v2:
- Various cleanups, as suggested by Shawn Guo
- Patch "dt-bindings: arm: fsl: Add i.MX50 based boards" is new
- Squashed patch "ARM: dts: imx50-kobo-aura: Enable USB support" into
	patch 3 ("ARM: dts: imx50: Add Kobo Aura DTS")
- Dropped patch "ARM: dts: imx50: Add PHY node for usbotg and adjust
	clocks" because it was already merged into the imx tree
- Dropped patch "ARM: dts: imx50: Fix the numbering of the I2C
	controllers", because a similar one was merged into the imx tree
- Added Rob Herring's Reviewed-by tag to patch 1 ("dt-bindings: Add
	vendor prefix for Rakuten Kobo, Inc.")

A lot of functionality is still missing:
- poweroff/reboot, RTC, and battery monitoring support, as well as a PWM
  channel for the display backlight are provided by a custom embedded
  controller, which will be supported by a future patchset.
  The EC driver will also tell the EC to keep the board powered on;
  otherwise the EC will power the board off after about ten seconds
  (presumably to avoid battery drain if the OS is missing or corrupted)
- The touchscreen controller, eKTF2132, currently doesn't have a
  mainline driver.
- The e-paper display controller (EPDC) embedded in the i.MX50 SoC will
  need a whole new DRM driver, devicetree bindings, etc.
- The TPS65185 PMIC, which generates the voltages necessary for driving
  the E Ink panel, also needs a driver
- The backlight doesn't quite fit the existing pwm-backlight DT binding,
  because it uses an additional GPIO to boost the brightness. This
  requires some devicetree work
- Linux doesn't currently support suspend-to-ram on i.MX50

In order to keep the system running when CONFIG_PM is enabled, the
following fix is also required:

[PATCH v2 3/3] ARM: dts: imx50: Add Kobo Aura DTS

[Jonathan Neuschäfer]

The Kobo Aura is an e-book reader released in 2013.

With the devicetree in its current state, the kernel will boot and run
for about ten seconds. To solve this, the embedded controller needs to
be told that the system should stay powered on. This will be done in a
later patchset.

- The IOMUXC mode bits for the SD interfaces were taken from the
  vendor's U-Boot fork.
- The bus width of the eMMC is 4 bits in the vendor kernel, but I
  achieved better performance with 8 bits.
- The SDIO clock frequency for the WiFi chip is 25MHz in the vendor
  kernel, but the WiFi chip (BCM43362) supports 50MHz, which works
  reliably on this board and gives slightly better performance.
- The I2C pins' IOMUXC settings come from the vendor's U-Boot fork.

v2:
- Squash patch 4 ("ARM: dts: imx50-kobo-aura: Enable USB support")
- Sort pinctrl nodes alphabetically, as suggested by Shawn Guo
- Sort labeled nodes alphabetically, as suggested by Shawn Guo
- Make "status" the last property, as suggested by Shawn Guo
- Use KEY_RESERVED and EV_SW, as suggested by Shawn Guo
- Remove newlines between properties, as suggested by Shawn Guo

[PATCH v2 3/3] ARM: dts: imx50: Add Kobo Aura DTS

[Jonathan Neuschäfer]

The Kobo Aura is an e-book reader released in 2013.

With the devicetree in its current state, the kernel will boot and run
for about ten seconds. To solve this, the embedded controller needs to
be told that the system should stay powered on. This will be done in a
later patchset.

- The IOMUXC mode bits for the SD interfaces were taken from the
  vendor's U-Boot fork.
- The bus width of the eMMC is 4 bits in the vendor kernel, but I
  achieved better performance with 8 bits.
- The SDIO clock frequency for the WiFi chip is 25MHz in the vendor
  kernel, but the WiFi chip (BCM43362) supports 50MHz, which works
  reliably on this board and gives slightly better performance.
- The I2C pins' IOMUXC settings come from the vendor's U-Boot fork.

v2:
- Squash patch 4 ("ARM: dts: imx50-kobo-aura: Enable USB support")
- Sort pinctrl nodes alphabetically, as suggested by Shawn Guo
- Sort labeled nodes alphabetically, as suggested by Shawn Guo
- Make "status" the last property, as suggested by Shawn Guo
- Use KEY_RESERVED and EV_SW, as suggested by Shawn Guo
- Remove newlines between properties, as suggested by Shawn Guo
