Subject: [PATCH 01/16] ARM: dts: at91: sama5d2: Fix the label numbering for
flexcom functions
From: Tudor Ambarus <tudor.ambarus@...rochip.com>
The sama5d2 SoC has the following IPs: [uart0, uart4], {spi0, spi1}, {i2c0, i2c1}.
Label the flexcom functions in order:
flx0: uart5, spi2, i2c2
flx1: uart6, spi3, i2c3
flx2: uart7, spi4, i2c4
flx3: uart8, spi5, i2c5
flx4: uart9, spi6, i2c6
Some boards respected this scheme, others not. Fix the ones that didn't.
