2020-06-15soc: ti: Replace zero-length array with flexible-arrayGustavo A. R. Silva
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

It integrates pm_runtime in the core for keeping resources active while the remote is booted and holds a wake source while recoverying a remote processor after a firmware crash. It refactors the remoteproc device's allocation path to simplify the logic, fix a few cleanup bugs and to not clone const strings onto the heap.

Pull ARM SoC updates from Arnd Bergmann: "One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. There is ongoing cleanup for the integrator, tegra, imx, and omap2 platforms, with integrator getting very close to the goal of having zero code in arch/arm/, and omap2 moving more of the chip specifics from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well.

The Texas Instruments K3 Multicore SoC platforms have chipid module which is represented by CTRLMMR_xxx_JTAGID register and contains information about SoC id and revision. Bits: 31-28 VARIANT Device variant 27-12 PARTNO Part number 11-1 MFG Indicates TI as manufacturer (0x17) 1 Always 1 This patch adds corresponding driver to identify the TI K3 SoC family and revision, and registers this information with the SoC bus. It is available under /sys/devices/soc0/ for user space, and can be checked, where needed, in Kernel using soc_device_match(). Identification is done by: - checking MFG to be TI ID - retrieving Device variant (revision) - retrieving Part number and convert it to the family - retrieving machine from DT "/model" Example J721E: # cat /sys/devices/soc0/{machine,family,revision} Texas Instruments K3 J721E SoC J721E SR1.0 Example AM65x: # cat /sys/devices/soc0/{machine,family,revision} Texas Instruments AM654 Base Board AM65X SR1.0 Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Reviewed-by: Lokesh Vutla <lokeshvutla@ti.com> Reviewed-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@oracle.com>
2020-05-26cpuidle: Convert Qualcomm SPM driver to a generic CPUidle driverStephan Gerhold
The Qualcomm SPM cpuidle driver seems to be the last driver still using the generic ARM CPUidle infrastructure. Converting it actually allows us to simplify the driver, and we end up being able to remove more lines than adding new ones: - We can parse the CPUidle states in the device tree directly with dt_idle_states (and don't need to duplicate that functionality into the spm driver). - Each "saw" device managed by the SPM driver now directly registers its own cpuidle driver, removing the need for any global (per cpu) state. The device tree binding is the same, so the driver stays compatible with all old device trees.

2020-05-22soc: fsl: qe: Replace one-element array and use struct_size() helperGustavo A. R. Silva
The current codebase makes use of one-element arrays in the following form: struct something { int length; u8 data[1]; }; struct something *instance; instance = kmalloc(sizeof(*instance) + size, GFP_KERNEL); instance->length = size; memcpy(instance->data, source, size); but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. So, replace the one-element array with a flexible-array member. Also, make use of the new struct_size() helper to properly calculate the size of struct qe_firmware. This issue was found with the help of Coccinelle and, audited and fixed _manually_.
