[U-Boot] [PATCH v2] mx6: clock: Fix the calculation of PLL_ENET frequency

[U-Boot] [PATCH 0/2] i.MX6 (DQ/DLS): use macros for mux and pad declarations
by Eric Nelson 17 Dec '13

17 Dec '13

Updates i.MX6DQ and i.MXDLS mux/pad declarations to be declared using macros to allow their use in a binary supporting all four variants of the pin-compatible processors. This patch set was broken into two parts to allow validation using "git show --word-diff". The patches apply to u-boot-imx/master with commit a31d3efa (a previous and superfluous white-space change) reverted. Compile-tested against all mx6 boards. Run-time tested against nitrogen6q.
