* ARM: dts: s5pv210: Correct interrupt name for bluetooth in AriesJonathan Bakker2022-06-061-1/+1
| | | | | | | | | | | | | | commit 3f5e3d3a8b895c8a11da8b0063ba2022dd9e2045 upstream. Correct the name of the bluetooth interrupt from host-wake to host-wakeup.

* arm: use fallback for random_get_entropy() instead of zeroJason A. Donenfeld2022-05-301-0/+1
| | | | | | | | | | | | | | | | | | | commit ff8a8f59c99f6a7c656387addc4d9f2247d75077 upstream. In the event that random_get_entropy() can't access a cycle counter or similar, falling back to returning 0 is really not the best we can do. Instead, at least calling random_get_entropy_fallback() would be preferable, because that always needs to return _something_, even falling back to jiffies eventually. It's not as though random_get_entropy_fallback() is super high precision or guaranteed to be entropic, but basically anything that's not zero all the time is better than returning zero all the time.

* arm[64]/memremap: don't abuse pfn_valid() to ensure presence of linear mapMike Rapoport2022-05-182-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 260364d112bc822005224667c0c9b1b17a53eafd upstream. The semantics of pfn_valid() is to check presence of the memory map for a PFN and not whether a PFN is covered by the linear map. The memory map may be present for NOMAP memory regions, but they won't be mapped in the linear mapping. Accessing such regions via __va() when they are memremap()'ed will cause a crash. On v5.4.y the crash happens on qemu-arm with UEFI [1]: <1>[ 0.084476] 8<--- cut here --- <1>[ 0.084595] Unable to handle kernel paging request at virtual address dfb76000 <1>[ 0.084938] pgd = (ptrval) <1>[ 0.085038] [dfb76000] *pgd=5f7fe801, *pte=00000000, *ppte=00000000 ... <4>[ 0.093923] [<c0ed6ce8>] (memcpy) from [<c16a06f8>] (dmi_setup+0x60/0x418) <4>[ 0.094204] [<c16a06f8>] (dmi_setup) from [<c16a38d4>] (arm_dmi_init+0x8/0x10) <4>[ 0.094408] [<c16a38d4>] (arm_dmi_init) from [<c0302e9c>] (do_one_initcall+0x50/0x228) <4>[ 0.094619] [<c0302e9c>] (do_one_initcall) from [<c16011e4>] (kernel_init_freeable+0x15c/0x1f8) <4>[ 0.094841] [<c16011e4>] (kernel_init_freeable) from [<c0f028cc>] (kernel_init+0x8/0x10c) <4>[ 0.095057] [<c0f028cc>] (kernel_init) from [<c03010e8>] (ret_from_fork+0x14/0x2c) On kernels v5.10.y and newer the same crash won't reproduce on ARM because commit b10d6bca8720 ("arch, drivers: replace for_each_membock() with for_each_mem_range()") changed the way memory regions are registered in the resource tree, but that merely covers up the problem. On ARM64 memory resources registered in yet another way and there the issue of wrong usage of pfn_valid() to ensure availability of the linear map is also covered. Implement arch_memremap_can_ram_remap() on ARM and ARM64 to prevent access to NOMAP regions via the linear mapping in memremap().

Problem is, this change was only validated with an am437x-based board, where the clocks are effectively correctly defined and referenced. But on am33xx, the ADC clock is also correctly defined but is not referenced with a clock phandle as it ought to be. The touchscreen bindings clearly state that the clocks/clock-names properties are mandatory, but they have been forgotten in one DTSI. This was probably not noticed in the first place because of the clock actually existing and the clk_get() call going through all the tree anyway.

| | | | | | | | | | | | | | | | | [ Upstream commit 0e486fe341fabd8e583f3d601a874cd394979c45 ] The MCLK of the WM8731 on the AT91SAM9G20-EK board is connected to the PCK0 output of the SoC and is expected to be set to 12MHz. Previously this was mapped using pre-common clock API calls in the audio machine driver but the conversion to the common clock framework broke that so describe things in the DT instead.

The TRM "Table 12-348. VPE_SYSCONFIG" says that the value for SMART_IDLE is "0x2: Same behavior as bit-field value of 0x1". But if the SMART_IDLE value is used, PM_VPE_PWRSTST LASTPOWERSTATEENTERED bits always show value of 3. Let's fix the issue by dropping SMART_IDLE for vpe.

* clocksource/drivers/timer-ti-dm: Fix regression from errata i940 fixDrew Fustini2022-04-082-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit bceaae3bac0ce27c549bb050336d8d08abc2ee54 ] The existing fix for errata i940 causes a conflict for IPU2 which is using timer 3 and 4. From arch/arm/boot/dts/dra7-ipu-dsp-common.dtsi: &ipu2 { mboxes = <&mailbox6 &mbox_ipu2_ipc3x>; ti,timers = <&timer3>; ti,watchdog-timers = <&timer4>, <&timer9>; }; The conflict was noticed when booting mainline on the BeagleBoard X15 which has a TI AM5728 SoC: remoteproc remoteproc1: 55020000.ipu is available remoteproc remoteproc1: powering up 55020000.ipu remoteproc remoteproc1: Booting fw image dra7-ipu2-fw.xem4 omap-rproc 55020000.ipu: could not get timer platform device omap-rproc 55020000.ipu: omap_rproc_enable_timers failed: -19 remoteproc remoteproc1: can't start rproc 55020000.ipu: -19 This change modifies the errata fix to instead use timer 15 and 16 which resolves the timer conflict.
