| * | soc/fsl/qe: fix err handling of ucc_of_parse_tdmWen Yang2019-01-041-55/+0
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there are some issues with the ucc_of_parse_tdm function: 1, a possible null pointer dereference in ucc_of_parse_tdm, detected by the semantic patch deref_null.cocci, with the following warning: drivers/soc/fsl/qe/qe_tdm.c:177:21-24: ERROR: pdev is NULL but dereferenced. 2, dev gets modified, so in any case that devm_iounmap() will fail even when the new pdev is valid, because the iomap was done with a different pdev. 3, there is no driver bind with the "fsl,t1040-qe-si" or "fsl,t1040-qe-siram" device. So allocating resources using devm_*() with these devices won't provide a cleanup path for these resources when the caller fails. This patch fixes them.

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.

Leading to a 27% speedup for our context switch benchmark on Power9. - Improvements to our handling of SLB multi-hit errors. We now print more debug information when they occur, and try to continue running by flushing the SLB and reloading, rather than treating them as fatal. - Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9). - Add support for physical memory up to 2PB in the linear mapping on 64-bit Book3S. We only support up to 512TB as regular system memory, otherwise the percpu allocator runs out of vmalloc space. - Add stack protector support for 32 and 64-bit, with a per-task canary. - Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP. - Support recognising "big cores" on Power9, where two SMT4 cores are presented to us as a single SMT8 core. - A large series to cleanup some of our ioremap handling and PTE flags. - Add a driver for the PAPR SCM (storage class memory) interface, allowing guests to operate on SCM devices (acked by Dan). - Changes to our ftrace code to handle very large kernels, where we need to use a trampoline to get to ftrace_caller(). And many other smaller enhancements and cleanups.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This doesn't work without the previous ARM SoC device-tree pull, because the R8A77970 driver is missing a header file that came from that pull.

| | | | | | | | | | | | | | | | | | | | | | Rework portal mapping for PPC and ARM. The PPC devices require a cacheable coherent mapping while ARM will work with a non-cachable/write combine mapping. This also eliminates the need for manual cache flushes on ARM. This also fixes the code so sparse checking is clean.
