Thanks Shawn,
I noticed that Otavio's e-mail had a bad reference for the list, and we've veered off the original topic.

There are currently 8 pads defined in U-Boot that aren't defined in the Linux kernel sources:
SD2_CLK__USDHC2_CLK SD2_CMD__USDHC2_CMD SD2_DAT0__USDHC2_DAT0 SD2_DAT1__USDHC2_DAT1 SD2_DAT2__USDHC2_DAT2 SD2_DAT3__USDHC2_DAT3
They are the following ones in kernel.
MX6QDL_PAD_SD2_CLK__SD2_CLK MX6QDL_PAD_SD2_CMD__SD2_CMD MX6QDL_PAD_SD2_DAT0__SD2_DATA0 MX6QDL_PAD_SD2_DAT1__SD2_DATA1 MX6QDL_PAD_SD2_DAT2__SD2_DATA2 MX6QDL_PAD_SD2_DAT3__SD2_DATA3
This comment was about SL, not DQ or DLS.
And my comments were wrong.
I used a tool to do a quick comparison and didn't check my work.
The reality is that U-Boot's pad declarations for SL are almost non-existent: http://git.denx.de/u-boot.git/?p=u-boot.git;a=blob;f=arch/arm/include/asm/ar...
The 8 declarations that are present all have name mis-matches with the Linux kernel (USDHC2 vs. SD2, UART1_RXD vs. UART1_RX_DATA).
They are named per IOMUXC registers description in reference manual.
UART1_RXD__UART1_RXD UART1_TXD__UART1_TXD
Yes, kernel does not define them. That's because the reference manual does not define them. The macros in kernel are generated from reference manual data source.
Cool. Thanks for your work on the kernel side. Things there are in much better shape than in the U-Boot source tree.

Eric
