[ Upstream commit 31edaa6e7fd8143085a6a60c564447c07e76ed9f ]
Signals available on both i.MX6UL and i.MX6ULL should have the same name because it is the case of all others common signals, it avoids to make mistakes (use the wrong ones) and it makes writing device tree files less complicated. For example:
imx6ul-imx6ull-board.dtsi: ... pinctrl_uart5: uart5grp { fsl,pins = < MX6UL_PAD_UART5_TX_DATA__UART5_DCE_TX 0x1b0b1 MX6UL_PAD_UART5_RX_DATA__UART5_DCE_RX 0x1b0b1 >; };
imx6ul-board.dts: #include <imx6ul.dtsi> #include <imx6ul-imx6ull-board.dtsi> ...
imx6ull-board.dts: #include <imx6ull.dtsi> #include <imx6ul-imx6ull-board.dtsi> ...
Without this patch, the imx6ull-board.dtb will use MX6UL_PAD_UART5_RX_DATA__UART5_DCE_RX instead of MX6ULL_PAD_UART5_RX_DATA__UART5_DCE_RX and the uart5 will be misconfigured.
