Colibri modules need to be powered using the power pins 3V3 and AVDD_AUDIO. Add fixed regulators which represent this power rails. Potentially, those power rails could be switched on a carrier board. A carrier board device tree could add a own regulator with a GPIO, and reference that regulator in a vin-supply property of those new module level system regulators. This also synchronize the name of the +3.3V regulator with the one used in the Colibri VF50/VF61 device tree.

Only i.MX 7Dual SoC supports CPU frequencies of up to 1GHz. The i.MX 7Solo can run with up to 800MHz and does so without making use of DVFS usually. While the device tree clearly specified a too fast operating point for i.MX 7Solo, the kernel did not used it in practise so far because the CPUfreq driver does not get loaded on i.MX 7Solo devices (since the fsl,imx7s compatible string is not in the list of devices making use of the cpufreq-dt driver...).

bc677ff4 adds a device-tree property to specify that an external watchdog reset is used to reset other portions of the board and not just the IMX6 SoC. This adds the property to the proper watchdog as well as the pinmux for the Gateworks Ventana boards that use this external watchdog reset to reset the PMIC which will reset all the PMIC power rails and not just a chip-level IMX6 reset. This helps to work around various system issues that can cause a hang when coming out of reset. Signed-off-by: Tim Harvey <tharvey@gateworks.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

The dma-mapping core and the implementations do not change the DMA attributes passed by pointer. Thus the pointer can point to const data. However the attributes do not have to be a bitfield. Instead unsigned long will do fine: 1. This is just simpler. Both in terms of reading the code and setting attributes. Instead of initializing local attributes on the stack and passing pointer to it to dma_set_attr(), just set the bits. 2. It brings safeness and checking for const correctness because the attributes are passed by value. Semantic patches for this change (at least most of them): virtual patch virtual context @r@ identifier f, attrs; @@ f(..., - struct dma_attrs *attrs + unsigned long attrs , ...) { ... } @@ identifier r.f; @@ f(..., - NULL + 0 ) and // Options: --all-includes virtual patch virtual context @r@ identifier f, attrs; type t;...
