[PATCH] ARM: dts: imx6q-bx50v3/imx6q-b450v3/imx6q-b650v3: change pca953x GPIO default settings Ken Lin <yungching0725@gmail.com> - 2017-02-03 02:30 +0100

| Subject | [PATCH] ARM: dts: imx6q-bx50v3/imx6q-b450v3/imx6q-b650v3: change pca953x GPIO default settings |
| Message-ID | <t6ARj-3hn-11@gated-at.bofh.it> |
Leave pca953x P06,P07 pins on b850v3 platform and P06 pin on b450v3/b650v3 unconfigured
in the kernel space since they could be configured as DP1_RST and DP2_RST by the applications
for the DP FW update support
