| * | soc: fsl: dpio: add frame list format supportHoria Geantă2018-09-211-0/+242
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for dpaa2_fd_list format, i.e. dpaa2_fl_entry structure and accessors. Frame list entries (FLEs) are similar, but not identical to FDs: + "F" (final) bit - FMT[b'01] is reserved - DD, SC, DROPP bits (covered by "FD compatibility" field in FLE case) - FLC[5:0] not used for stashing Signed-off-by: Horia Geantă <horia.geanta@nxp.com> Acked-by: Li Yang <leoyang.li@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* | soc: fsl: qbman: add APIs to retrieve the probing statusLaurentiu Tudor2018-09-272-0/+16
|/ | | | | | | | | | | | | | | | | Add a couple of new APIs to check the probing status of qman and bman: 'int bman_is_probed()' and 'int qman_is_probed()'. They return the following values. * 1 if qman/bman were probed correctly * 0 if qman/bman were not yet probed * -1 if probing of qman/bman failed Drivers that use qman/bman driver services are required to use these APIs before calling any functions exported by qman or bman drivers or otherwise they will crash the kernel. The APIs will be used in the following couple of qbman portal patches and later in the series in the dpaa1 ethernet driver.

* staging: fsl-mc: Move DPIO from staging to drivers/soc/fslRoy Pledge2018-07-243-0/+730
| | | | | | | | | | | | | | Move the NXP DPIO (Datapath I/O Driver) out of the drivers/staging directory and into the drivers/soc/fsl directory. The DPIO driver enables access to Queue and Buffer Manager (QBMAN) hardware on NXP DPAA2 devices. This is a prerequisite to moving the DPAA2 Ethernet driver out of staging.

* net/wan/fsl_ucc_hdlc: add hdlc-bus supportHolger Brunck2017-05-181-0/+5
| | | | | | | | | | | | | | | | | | This adds support for hdlc-bus mode to the fsl_ucc_hdlc driver. This can be enabled with the "fsl,hdlc-bus" property in the DTS node of the corresponding ucc. This aligns the configuration of the UPSMR and GUMR registers to what is done in our ucc_hdlc driver (that only support hdlc-bus mode) and with the QuickEngine's documentation for hdlc-bus mode. GUMR/SYNL is set to AUTO for the busmode as in this case the CD signal is ignored. The brkpt_support is enabled to set the HBM1 bit in the CMXUCR register to configure an open-drain connected HDLC bus.

Plus a few changes from Scott which came in a bit late. And then various fixes, mostly minor. Summary highlights: - rework the Linux page table geometry to lower memory usage on 64-bit Book3S (IBM chips) using the Hash MMU. - support for a new device tree binding for discovering CPU features on future firmwares. - Freescale updates from Scott: "Includes a fix for a powerpc/next mm regression on 64e, a fix for a kernel hang on 64e when using a debugger inside a relocated kernel, a qman fix, and misc qe improvements."
