[PATCH 2/6] ARM: dts: keystone-k2g-evm: Fix botched up merge

[Vignesh R]

spi1 and ecap0 pinmuxes ended up under root node instead of k2g_pinctrl
node. Fix this by moving them under k2g_pinctrl node.

[PATCH 3/6] ARM: dts: keystone-k2g: Move ti,non-removable property to board dts

[Vignesh R]

On 66AK2G EVM mmc1 is connected to emmc whereas 66AK2G ICE baord has SD
card slot connected to mmc1. Therefore move emmc specific
ti,non-removable property from SoC file to EVM's dts file.

[PATCH 6/6] ARM: configs: keystone_defconfig: Enable few peripheral drivers

Please submit a patch also to enable all these peripherals
in multi-v7 config. Just enable all remainder
options enabled in keystone config also in multi-v7.

Am pushing this series to next now.

Series applied. Please submit the follow up patch for
multi-v7 config.

K2 Platforms don't boot out of multi_v7_defconfig by default, because K2
platforms require CONFIG_ARM_LPAE(which is disabled in multi-v7).

If the intention is to just have all drivers enabled in
keystone_defconfig to be added to multi_v7, I can prepare a patch for
that and test with local patch to enable LPAE.

Yes. Please send a patch for it.
