2018-11-21ARM: 8809/1: proc-v7: fix Thumb annotation of cpu_v7_hvc_switch_mmArd Biesheuvel1-1/+1
commit 6282e916f774e37845c65d1eae9f8c649004f033 upstream. Due to what appears to be a copy/paste error, the opening ENTRY() of cpu_v7_hvc_switch_mm() lacks a matching ENDPROC(), and instead, the one for cpu_v7_smc_switch_mm() is duplicated. Given that it is ENDPROC() that emits the Thumb annotation, the cpu_v7_hvc_switch_mm() routine will be called in ARM mode on a Thumb2 kernel, resulting in the following splat: Internal error: Oops - undefined instruction: 0 [#1] SMP THUMB2 Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.18.0-rc1-00030-g4d28ad89189d-dirty #488 Hardware name: QEMU KVM Virtual Machine, BIOS 0.0.0 02/06/2015 PC is at cpu_v7_hvc_switch_mm+0x12/0x18 LR is at flush_old_exec+0x31b/0x570 pc : [<c0316efe>] lr : [<c04117c7>] psr: 00000013 sp : ee899e50 ip : 00000000 fp : 00000001 r10: eda28f34 r9 : eda31800 r8 : c12470e0 r7 : eda1fc00 r6 : eda53000 r5 : 00000000 r4 : ee88c000 r3 : c0316eec r2 : 00000001 r1 : eda53000 r0 : 6da6c000 Flags: nzcv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Note the 'ISA ARM' in the last line.

2018-11-21ARM: dts: imx6ull: keep IMX6UL_ prefix for signals on both i.MX6UL and i.MX6ULLSébastien Szymanski1-5/+13
[ Upstream commit 31edaa6e7fd8143085a6a60c564447c07e76ed9f ] Signals available on both i.MX6UL and i.MX6ULL should have the same name because it is the case of all others common signals, it avoids to make mistakes (use the wrong ones) and it makes writing device tree files less complicated. For example: imx6ul-imx6ull-board.dtsi: ... pinctrl_uart5: uart5grp { fsl,pins = < MX6UL_PAD_UART5_TX_DATA__UART5_DCE_TX 0x1b0b1 MX6UL_PAD_UART5_RX_DATA__UART5_DCE_RX 0x1b0b1 >; }; imx6ul-board.dts: #include <imx6ul.dtsi> #include <imx6ul-imx6ull-board.dtsi> ... imx6ull-board.dts: #include <imx6ull.dtsi> #include <imx6ul-imx6ull-board.dtsi> ... Without this patch, the imx6ull-board.dtb will use MX6UL_PAD_UART5_RX_DATA__UART5_DCE_RX instead of MX6ULL_PAD_UART5_RX_DATA__UART5_DCE_RX and the uart5 will be misconfigured.

commit 672f33198bee21ee91e6af2cb8f67cfc8bc97ec1 upstream. The cooling device properties, like "#cooling-cells" and "dynamic-power-coefficient", should either be present for all the CPUs of a cluster or none. If these are present only for a subset of CPUs of a cluster then things will start falling apart as soon as the CPUs are brought online in a different order. For example, this will happen because the operating system looks for such properties in the CPU node it is trying to bring up, so that it can register a cooling device. Add such missing properties. Fix other missing properties (clocks, OPP, clock latency) as well to make it all work.

[ Upstream commit 3a58ac65e2d7969bcdf1b6acb70fa4d12a88e53e ] IO_SPACE_LIMIT is the ending address of the PCI IO space, i.e something like 0xfffff (and not 0x100000). Therefore, when offset = 0xf0000 is passed as argument, this function fails even though the offset + SZ_64K fits below the IO_SPACE_LIMIT. This makes the last chunk of 64 KB of the I/O space not usable as it cannot be mapped. This patch fixes that by substracing 1 to offset + SZ_64K, so that we compare the addrss of the last byte of the I/O space against IO_SPACE_LIMIT instead of the address of the first byte of what is after the I/O space.

I have one device that hits this error almost on every boot, and another one that hits it only rarely with the other ones I've used behave without problems. I'm not sure if the issue is related to a particular eMMC card model, but in case it is, both of the machines with issues have: # cat /sys/class/mmc_host/mmc1/mmc1:0001/manfid \ /sys/class/mmc_host/mmc1/mmc1:0001/oemid \ /sys/class/mmc_host/mmc1/mmc1:0001/name 0x000045 0x0100 SEM16G and the working ones have: 0x000011 0x0100 016G92 Note that "ti,non-removable" is different as omap_hsmmc_reg_get() does not call omap_hsmmc_disable_boot_regulators() if no_regulator_off_init is set. And currently we set no_regulator_off_init only for "ti,non-removable" and not for "non-removable". It seems that we should have "non-removable" with some other mmc generic property behave in the same way instead of having to use a non-generic property. But let's fix the issue first.

2018-10-04ARM: OMAP2+: Fix module address for modules using mpu_rt_idxTony Lindgren1-0/+37
[ Upstream commit 1dbcb97c656eed1a244c960b8b3a469c3d20ce7b ] If we use device tree data for a module interconnect target we want to map the control registers from the module start. Legacy hwmod platform data however is using child IP offsets for cpsw module with mpu_rt_idx. In cases where we have the interconnect target module already using device tree data with legacy hwmod platform data still around, the sysc register area is not adjusted for mpu_rt_idx causing wrong registers being accessed. Let's fix the issue for mixed dts and platform data mode by ioremapping the module registers using child IP offset if mpu_rt_idx is set. For device tree only data there's no reason to use mpu_rt_idx.

2018-10-04ARM: mvebu: declare asm symbols as character arrays in pmsu.cEthan Tuttle1-3/+3
[ Upstream commit d0d378ff451a66e486488eec842e507d28145813 ] With CONFIG_FORTIFY_SOURCE, memcpy uses the declared size of operands to detect buffer overflows. If src or dest is declared as a char, attempts to copy more than byte will result in a fortify_panic(). Address this problem in mvebu_setup_boot_addr_wa() by declaring mvebu_boot_wa_start and mvebu_boot_wa_end as character arrays. Also remove a couple addressof operators to avoid "arithmetic on pointer to an incomplete type" compiler error. See commit 54a7d50b9205 ("x86: mark kprobe templates as character arrays, not single characters") for a similar fix. Fixes "detected buffer overflow in memcpy" error during init on some mvebu systems (armada-370-xp, armada-375): (fortify_panic) from (mvebu_setup_boot_addr_wa+0xb0/0xb4) (mvebu_setup_boot_addr_wa) from (mvebu_v7_cpu_pm_init+0x154/0x204) (mvebu_v7_cpu_pm_init) from (do_one_initcall+0x7c/0x1a8) (do_one_initcall) from (kernel_init_freeable+0x1bc/0x254) (kernel_init_freeable) from (kernel_init+0x8/0x114) (kernel_init) from (ret_from_fork+0x14/0x2c) Signed-off-by: Ethan Tuttle <ethan@ethantuttle.com> Tested-by: Ethan Tuttle <ethan@ethantuttle.com> Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

[ Upstream commit 6d609b35c815ba20132b7b64bcca04516bb17c56 ] When the RTC lock and unlock functions were introduced it was likely assumed that they would always be called from irq enabled context, hence the use of local_irq_disable/enable. This is no longer true as the RTC+DDR path makes a late call during the suspend path after irqs have been disabled to enable the RTC hwmod which calls both unlock and lock, leading to IRQs being reenabled through the local_irq_enable call in omap_hwmod_rtc_lock call. To avoid this change the local_irq_disable/enable to local_irq_save/restore to ensure that from whatever context this is called the proper IRQ configuration is maintained.

[ Upstream commit cd4806911cee3901bc2b5eb95603cf1958720b57 ] For most of Exynos SoCs, Power Management Unit (PMU) address space is mapped into global variable 'pmu_base_addr' very early when initializing PMU interrupt controller. A lot of other machine code depends on it so when doing iounmap() on this address, clear the global as well to avoid usage of invalid value (pointing to unmapped memory region). Properly mapped PMU address space is a requirement for all other machine code so this fix is purely theoretical. Boot will fail immediately in many other places after following this error path.

commit 6e1811900b6fe6f2b4665dba6bd6ed32c6b98575 upstream. On all versions of Tegra30 Cardhu, the reset signal to the NXP PCA9546 I2C mux is connected to the Tegra GPIO BB0. Currently, this pin on the Tegra is not configured as a GPIO but as a special-function IO (SFIO) that is multiplexing the pin to an I2S controller. On exiting system suspend, I2C commands sent to the PCA9546 are failing because there is no ACK. Although it is not possible to see exactly what is happening to the reset during suspend, by ensuring it is configured as a GPIO and driven high, to de-assert the reset, the failures are no longer seen. Please note that this GPIO is also used to drive the reset signal going to the camera connector on the board. However, given that there is no camera support currently for Cardhu, this should not have any impact.
