2019-07-20dt-bindings: Ensure child nodes are of type 'object'Rob Herring2-0/+2
Properties which are child node definitions need to have an explict type. Otherwise, a matching (DT) property can silently match when an error is desired. Fix this up tree-wide. Once this is fixed, the meta-schema will enforce this on any child node definitions.

Mixing array constraints like 'maxItems' and string or integer value constraints like 'minimum' don't make sense. Also, with only value constraints, it is implied we have a single value.

2019-03-18spi: spi-fsl-spi: support use of the SPISEL_BOOT signal on MPC8309Rasmus Villemoes1-0/+4
The MPC8309 has a dedicated signal, SPISEL_BOOT, usually used as chip select for the flash device from which the bootloader is loaded. It is not an ordinary gpio, but is simply controlled via the SPI_CS register in the system configuration. To allow accessing such a spi slave, we need to teach fsl_spi_cs_control() how to control the SPISEL_BOOT signal. To distinguish the gpio-controlled slaves, continue to have those use chip_select values of 0..ngpios-1, and use chip_select == ngpios for the boot flash. I'm not too happy with all the ifdeffery, but it seems to be necessary for guarding the sysdev/fsl_soc.h and use of get_immrbase() (spi-fsl-lib.c already contains similar ifdeffery). Googling suggests that the MPC8306 is similar, with the SPI_CS register at the same offset. Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk> Signed-off-by: Mark Brown <broonie@kernel.org>

2019-01-07dt-bindings: spi: Adjust the bindings for the FSL QSPI driverFrieder Schrempf1-10/+8
Adjust the documentation of the new SPI memory interface based driver to reflect the new drivers settings. The "old" driver was using the "fsl,qspi-has-second-chip" property to select one of two dual chip setups (two chips on one bus or two chips on separate buses). And it used the order in which the subnodes are defined in the dt to select the CS, the chip is connected to. Both methods are wrong and in fact the "reg" property should be used to determine which bus and CS a chip is connected to. This also enables us to use different setups than just single chip, or symmetric dual chip. So the porting of the driver from the MTD to the SPI framework actually enforces the use of the "reg" properties and makes "fsl,qspi-has-second-chip" superfluous. As all boards that have "fsl,qspi-has-second-chip" set, also have correct "reg" properties, the removal of this property shouldn't lead to any incompatibilities. The only compatibility issues I can see are with imx6sx-sdb.dts and imx6sx-sdb-reva.dts, which have their reg properties set incorrectly (see explanation here: [2]), all other boards should stay compatible. Also the "big-endian" flag was removed, as this setting is now selected by the driver, depending on which SoC is in use.
