[PATCH 01/23] ARM: zii-common: Gate rdu_i210_invm() call with CONFIG_PCI_IMX6

[Andrey Smirnov]

There's no reason to have rdu_i210_invm() inicalli if CONFIG_PCI_IMX6
is not selected. Add appropriate ifdef to handle that.

Hmm, not sure I understand what you mean. I210 card and its INVM won't
appear if PCIe is not enabled, that's why there's no reason to have
rdu_i210_invm() initcall if CONFIG_PCI_IMX6 is _not_ selected. Did I
miss something?

Erm, no. It was me who missed something, I had a knot in my brain :-|

[PATCH 03/23] ARM: zii-imx7d-dev: Fix compatible name

[Andrey Smirnov]

Fix compatible name use in zii_imx7d_rpu2_coredevices_init(). Upstream
uses "zii,imx7d-rpu2" and so should we.

[PATCH 05/23] i2c: Port of_find_i2c_device_by_node() from Linux

[Andrey Smirnov]

Port of_find_i2c_device_by_node() from Linux in order to allow looking
i2c_client up by corresponding DT node. Useful for interacting with
identical raw/driverless I2C devices that are not found on the same
bus between board variants.

Can we have a sanity check if this is actually a I2C device? At least
a test for dev->bus == &i2c_bus would be nice.

Subject: [PATCH] i2c: Port of_find_i2c_device_by_node() from Linux

Port of_find_i2c_device_by_node() from Linux in order to allow looking
i2c_client up by corresponding DT node. Useful for interacting with
identical raw/driverless I2C devices that are not found on the same
bus between board variants.

The zii-vf610 doesn't set CONFIG_MACH_ZII_COMMON, so the common env is not
compiled in which results in a linker error. What's the correct way to
fix that? Specify CONFIG_MACH_ZII_COMMON for the vf610 board?

Ugh, sorry about that. I always select all of those boards at the same
time, so I missed that. Yes, I think CONFIG_MACH_ZII_COMMON for VF610
would be the way to go. Let me know if you want me to re-spin this

That shouldn't be necessary, thanks. I added a select to
CONFIG_MACH_ZII_COMMON, it compiles without errors now.

[PATCH 12/23] ARM: zii-imx6q-rdu2: Register SD card slot with BBU

Register SD card slot with BBU. This is really useful for development
since this allows to update the bootloader on SD card without having
to take it out of the device.
