[PATCH AUTOSEL 6.4 01/17] arm64: dts: rockchip: correct wifi interrupt flag in eaidk-610

[Sasha Levin]

From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

[ Upstream commit 8183bb7e291b7818f49ea39687c2fafa01a46e27 ]

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning: GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE.

Correct the interrupt flags, assuming the author of the code wanted same
logical behavior behind the name "ACTIVE_xxx", this is:
  ACTIVE_HIGH  => IRQ_TYPE_LEVEL_HIGH

[PATCH AUTOSEL 6.4 11/17] ARM: dts: integrator: fix PCI bus dtc warnings

[Sasha Levin]

From: Lin Yujun <linyujun809@huawei.com>

[ Upstream commit 42ff49a1967af71772b264009659ce181f7d2d2a ]

An warning is reported when allmodconfig is used to compile the kernel of the ARM architecture:

arch/arm/boot/dts/arm/integratorap.dts:161.22-206.4: Warning (pci_bridge): /pciv3@62000000: node name is not "pci" or "pcie"

Change the node name to pci to clear the build warning.

[PATCH AUTOSEL 6.4 13/17] i2c: imx-lpi2c: return -EINVAL when i2c peripheral clk doesn't work

[Sasha Levin]

From: Carlos Song <carlos.song@nxp.com>

[ Upstream commit b610c4bbd153c2cde548db48559e170905d7c369 ]

On MX8X platforms, the default clock rate is 0 if without explicit
clock setting in dts nodes. I2c can't work when i2c peripheral clk
rate is 0.

Add a i2c peripheral clk rate check before configuring the clock
register. When i2c peripheral clk rate is 0 and directly return
-EINVAL.
