Subject: mach-ipq40xx: import GPIO header from mach-snapgradon
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=a2830931490952b3130c22fd3259123b27ee9889;p=u-boot.git

mach-ipq40xx: import GPIO header from mach-snapgradon

Pinctrl driver was refactored and moved, but the required header that
it depends on was not included.

Fixes: 24d2908e987a ("pinctrl: qcom: move ipq4019 driver from mach-ipq40xx")
