Many changes were done in drivers/pinctrl/bcm/pinctrl-bcm2835.c between
5.4.171 and 5.4.179.
The following 3 patches do not apply any more:
* target/linux/bcm27xx/patches-5.4/950-0316-pinctrl-bcm2835-Add-support-for-BCM2711-pull-up-func.patch
This was already integrated in kernel v5.4-rc1, it was never needed.
* target/linux/bcm27xx/patches-5.4/950-0328-Revert-pinctrl-bcm2835-Pass-irqchip-when-adding-gpio.patch
* target/linux/bcm27xx/patches-5.4/950-0362-pinctrl-bcm2835-Change-init-order-for-gpio-hogs.patch
I think these were done to fix the problem which was really fixed in
commit 75278f1aff5e ("pinctrl: bcm2835: Change init order for gpio
hogs") from v5.4.175
target/linux/generic/backport-5.4/716-v5.5-net-sfp-move-fwnode-parsing-into-sfp-bus-layer.patch
Move fwnode_device_is_available to the same position as in kernel 5.10.
target/linux/layerscape/patches-5.4/302-dts-0083-arm64-ls1028a-qds-correct-bus-of-rtc.patch
Applied in commit 65816c1034769e714edb70f59a33bc5472d9e55f ("arm64: dts:
ls1028a-qds: move rtc node to the correct i2c bus")

Subject: [PATCH] PCI: aardvark: Fix initialization with old Marvell's Arm

Old ATF automatically power on pcie phy and does not provide SMC call for
|
|
phy power on functionality which leads to aardvark initialization failure:
|
|
|
|
[ 0.330134] mvebu-a3700-comphy d0018300.phy: unsupported SMC call, try updating your firmware
|
|
[ 0.338846] phy phy-d0018300.phy.1: phy poweron failed --> -95
|
|
[ 0.344753] advk-pcie d0070000.pcie: Failed to initialize PHY (-95)
|
|
[ 0.351160] advk-pcie: probe of d0070000.pcie failed with error -95
|
|
|
|
This patch fixes above failure by ignoring 'not supported' error in
|
|
aardvark driver. In this case it is expected that phy is already power on.
