[PATCH v1 00/11] arm64: dts: freescale: Add SPI aliases to Toradex SoMs

[Francesco Dolcini <francesco@dolcini.it>]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Toradex SoM families (Verdin, Apalis, Colibri, Aquila, Lino) and the
SMARC and OSM standards define the interfaces available to the carrier
board and their numbering or naming as part of the module pinout. The
Linux SPI bus number instead follows the SoC dtsi aliases where they
exist (i.MX8MM, i.MX8MP, i.MX8QM, i.MX8QXP) or is assigned dynamically
(i.MX91, i.MX93, i.MX95), so the bus number in sysfs and the spidev
device name do not match the module interface.

Add spiN aliases to the SoM dtsi files so the Linux bus number follows
the module interface numbering, zero-based like the existing
serial and can aliases: SPI_1 is spi0 and SPI_2 is spi1, SMARC SPI0 and
SPI1 map directly, OSM SPI_A is spi0 and SPI_B is spi1, the single
Colibri SPI is spi0. Where the SoC dtsi already gives the same
controller another alias, that inherited alias is deleted so each
controller carries a single one. SPI controllers that are not part of
the module pinout get no alias of their own.
