2021-07-27ARM: dts: omap4-l4-abe: Add McASP configurationPeter Ujfalusi1-16/+19
OMAP4 has a single McASP instance with single serializer and locked for DIT mode. To be able to enable the support the following fixes needed: - Add the DAT port ranges to the target module's ranges We can already fill in the op-mode and serial-dir for McASP as it only supports this configuration, but keep the module disabled as there is no known device available where it is used.

2021-07-27omap5-board-common: remove not physically existing vdds_1v8_main fixed-regulatorH. Nikolaus Schaller1-8/+1
This device tree include file describes a fixed-regulator connecting smps7_reg output (1.8V) to some 1.8V rail and consumers (vdds_1v8_main). This regulator does not physically exist. I assume it was introduced as a wrapper around smps7_reg to provide a speaking signal name "vdds_1v8_main" as label. This fixed-regulator without real function was not an issue in driver code until Commit 98e48cd9283d ("regulator: core: resolve supply for boot-on/always-on regulators") introduced a new check for regulator initialization which makes Palmas regulator registration fail: [ 5.407712] ldo1: supplied by vsys_cobra [ 5.412748] ldo2: supplied by vsys_cobra [ 5.417603] palmas-pmic 48070000.i2c:palmas@48:palmas_pmic: failed to register 48070000.i2c:palmas@48:palmas_pmic regulator The reason is that the supply-chain of regulators is too long and goes from ldo3 through the virtual vdds_1v8_main regulator and then back to smps7. This adds a cross-dependency of probing Palmas regulators and the fixed-regulator which leads to probe deferral by the new check and is no longer resolved. Since we do not control what device tree files including this one reference (either &vdds_1v8_main or &smps7_reg or both) we keep both labels for smps7 for compatibility.

2021-07-27ARM: dts: am43x-epos-evm: Reduce i2c0 bus speed for tps65218Dave Gerlach1-1/+1
Based on the latest timing specifications for the TPS65218 from the data sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206 from November 2014, we must change the i2c bus speed to better fit within the minimum high SCL time required for proper i2c transfer. When running at 400khz, measurements show that SCL spends 0.8125 uS/1.666 uS high/low which violates the requirement for minimum high period of SCL provided in datasheet Table 7.6 which is 1 uS. Switching to 100khz gives us 5 uS/5 uS high/low which both fall above the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low. Without this patch occasionally a voltage set operation from the kernel will appear to have worked but the actual voltage reflected on the PMIC will not have updated, causing problems especially with cpufreq that may update to a higher OPP without actually raising the voltage on DCDC2, leading to a hang.

2021-07-26printk: remove NMI trackingJohn Ogness1-2/+2
All NMI contexts are handled the same as the safe context: store the message and defer printing. There is no need to have special NMI context tracking for this. Using in_nmi() is enough. There are several parts of the kernel that are manually calling into the printk NMI context tracking in order to cause general printk deferred printing: arch/arm/kernel/smp.c arch/powerpc/kexec/crash.c kernel/trace/trace.c For arm/kernel/smp.c and powerpc/kexec/crash.c, provide a new function pair printk_deferred_enter/exit that explicitly achieves the same objective. For ftrace, remove the printk context manipulation completely. It was added in commit 03fc7f9c99c1 ("printk/nmi: Prevent deadlock when accessing the main log buffer in NMI"). The purpose was to enforce storing messages directly into the ring buffer even in NMI context. It really should have only modified the behavior in NMI context. There is no need for a special behavior any longer. All messages are always stored directly now. The console deferring is handled transparently in vprintk().

2021-07-26ARM: dts: meson8: Use a higher default GPU clock frequencyMartin Blumenstingl1-0/+5
We are seeing "imprecise external abort (0x1406)" errors during boot (which then cause the whole board to hang) on Meson8 (but not Meson8m2). These are observed while trying to access the GPU's registers when the MALI clock is running at it's default setting of 24MHz. The 3.10 vendor kernel uses 318.75MHz as "default" GPU frequency. Using that makes the "imprecise external aborts" go away. Add the assigned-clocks and assigned-clock-rates properties to also bump the MALI clock to 318.75MHz before accessing any of it's registers.

2021-07-23signal: Verify the alignment and size of siginfo_tEric W. Biederman1-0/+2
Update the static assertions about siginfo_t to also describe it's alignment and size. While investigating if it was possible to add a 64bit field into siginfo_t[1] it became apparent that the alignment of siginfo_t is as much a part of the ABI as the size of the structure. If the alignment changes siginfo_t when embedded in another structure can move to a different offset. Which is not acceptable from an ABI structure. So document that fact and add static assertions to notify developers if they change change the alignment by accident.

2021-07-23Revert "ARM: dts: imx6: Use correct SDMA script for SPI cores"Robin Gong1-4/+4
There are two ways for SDMA accessing SPBA devices: one is SDMA->AIPS ->SPBA(masterA port), another is SDMA->SPBA(masterC port). Please refer to the 'Figure 58-1. i.MX 6Dual/6Quad SPBA connectivity' of i.mx6DQ Reference Manual. SDMA provide the corresponding app_2_mcu/mcu_2_app and shp_2_mcu/mcu_2_shp script for such two options. So both AIPS and SPBA scripts should keep the same behaviour, the issue only caught in AIPS script sounds not solide. The issue is more likely as the ecspi errata ERR009165(http://www.nxp.com/docs/en/errata/IMX6DQCE.pdf): eCSPI: TXFIFO empty flag glitch can cause the current FIFO transfer to be sent twice So revert commit 'dd4b487b32a3' firstly.

2021-07-21drivers/firmware: consolidate EFI framebuffer setup for all archesJavier Martinez Canillas1-4/+1
The register_gop_device() function registers an "efi-framebuffer" platform device to match against the efifb driver, to have an early framebuffer for EFI platforms. But there is already support to do exactly the same by the Generic System Framebuffers (sysfb) driver. This used to be only for X86 but it has been moved to drivers/firmware and could be reused by other architectures. Also, besides supporting registering an "efi-framebuffer", this driver can register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers on non-X86 EFI platforms. For example, on aarch64 these drivers can only be used with DT and doesn't have code to register a "simple-frambuffer" platform device when booting with EFI. For these reasons, let's remove the register_gop_device() duplicated code and instead move the platform specific logic that's there to sysfb driver.

2021-07-21bus: Make remove callback return voidUwe Kleine-König3-8/+3
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.
