2019-07-17docs: powerpc: convert docs to ReST and rename to *.rstMauro Carvalho Chehab
Convert docs to ReST and add them to the arch-specific book. The conversion here was trivial, as almost every file there was already using an elegant format close to ReST standard. The changes were mostly to mark literal blocks and add a few missing section title identifiers. One note with regards to "--": on Sphinx, this can't be used to identify a list, as it will format it badly. This can be used, however, to identify a long hyphen - and "---" is an even longer one. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

2019-05-20soc: fsl: qbman_portals: add APIs to retrieve the probing statusLaurentiu Tudor
Add a couple of new APIs to check the probing status of the required cpu bound qman and bman portals: 'int bman_portals_probed()' and 'int qman_portals_probed()'. They return the following values. * 1 if qman/bman portals were all probed correctly * 0 if qman/bman portals were not yet probed * -1 if probing of qman/bman portals failed Portals are considered successful probed if no error occurred during the probing of any of the portals and if enough portals were probed to have one available for each cpu. The error handling paths were slightly rearranged in order to fit this new functionality without being too intrusive. Drivers that use qman/bman portal driver services are required to use these APIs before calling any functions exported by these drivers or otherwise they will crash the kernel. First user will be the dpaa1 ethernet driver, coming in a subsequent patch. Signed-off-by: Laurentiu Tudor <laurentiu.tudor@nxp.com> Signed-off-by: Li Yang <leoyang.li@nxp.com>

For example, any DPNI, bound to the dpaa2-eth driver, which is using DPIO devices will be unbound before its supplier device.

2019-01-08soc: fsl: dpio: use a cpumask to identify which cpus are unusedIoana Ciornei
The current implementation of the dpio driver uses a static next_cpu variable to keep track of the index of the next cpu available. This approach does not handle well unbinding and binding dpio devices in a random order. For example, unbinding a dpio and then binding it again with the driver, will generate the below error: $ echo dpio.5 > /sys/bus/fsl-mc/drivers/fsl_mc_dpio/unbind $ echo dpio.5 > /sys/bus/fsl-mc/drivers/fsl_mc_dpio/bind [ 103.946380] fsl_mc_dpio dpio.5: probe failed. Number of DPIOs exceeds NR_CPUS. [ 103.955157] fsl_mc_dpio dpio.5: fsl_mc_driver_probe failed: -34 -bash: echo: write error: No such device Fix this error by keeping a global cpumask of unused cpus that will be updated at every dpaa2_dpio_[probe,remove].

Let's change the function signature to return the pointer to memory or an error pointer on failure, and take an argument that lets us return the size of the aux data read. This way we can remove the cmd_db_read_aux_data_len() API entirely and also get rid of the memcpy operation from cmd_db to the caller. Updating the only user of this code shows that making this change allows us to remove a function and put the lookup where the user is.

This contains a firmware "ioctl" interface that was a little controversial at first, but the version we merged solved that by not exposing arbitrary firmware calls to user space. - The Amlogic Meson platform gains a "canvas" driver that is used for video processing and shared between different high-level drivers. The rest is more of the usual, mostly related to SoC specific power management support and core drivers in drivers/soc: - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new features related to power and reset control. - The Mediatek mt8183 and mt6765 SoC platforms gain support for their respective power management chips. - A new driver for NXP i.MX8, which need a firmware interface for power management. - The SCPI firmware interface now contains support estimating power usage of performance states - The NVIDIA Tegra "pmc" driver gains a few new features, in particular a pinctrl interface for configuring the pads. - Lots of small changes for Qualcomm, in particular the "smem" device driver. - Some cleanups for the TI OMAP series related to their sysc controller.
