Subject: [PATCH v2 1/2] ARM: dts: imx25-pinfunc: Use consistent naming for eSDHC
This file had several naming inconsistencies for eSDHC:
- the instances were named sometimes SDn, sometimes SDHCn, whereas they
are named ESDHCn in the reference manual, e.g.:
MX25_PAD_SD1_CMD__SD1_CMD
MX25_PAD_D15__SDHC1_DAT7
- the data ports were named sometimes DATAn, sometimes DATn like in the
reference manual, e.g.:
MX25_PAD_SD1_DATA0__SD1_DATA0
MX25_PAD_D15__SDHC1_DAT7
- in one case, the clock port was named DAT_CLK instead of CLK:
MX25_PAD_CSI_D7__SDHC2_DAT_CLK
This change:
- introduces new definitions using the naming from the reference
manual,
- keeps definitions using the legacy naming in order not to break
compatibility for out-of-tree users (they can be removed later),
- updates the in-tree files that were using the legacy naming.
