2020-09-15ARM: 9006/1: uncompress: Wait for ready and busy in debug printsLinus Walleij
For some platforms such as Qualcomm we need to wait for the UART to be ready before writing characters to the UART in the same manner as the macro in debug.S used with the main "Uncompressing Linux ..." text. Pass an extra temporary variable to writeb and make it call waituarttxrdy and busyuart just like the other decomression messages. Optionally it will also call waituartcts if and only if CONFIG_DEBUG_UART_FLOW_CONTROL is selected. After this the decompression debug messages work fine on Qualcomm platforms if you compile head.S with -DDEBUG.

2020-09-15ARM: 9005/1: debug: Select flow control for all debug UARTsLinus Walleij
Instead of a flow control selection mechanism specifically for 8250, make this available for all debug UARTs. If the debug UART supports waiting for CTS to be asserted, then this code can be activated for terminals that need it. We keep the defaults for EBSA110, Footbridge, Gemini and RPC so that this still works as expected for these older platforms: they assume that flow control shall be enabled for debug prints. I switch the location of the check for ifdef CONFIG_DEBUG_UART_FLOW_CONTROL from the actual debug UART drivers: the code would get compiled-out for 8250 and Tegra unless their custom config (or passing -DFLOW_CONTROL in the Tegra case) was not set. Instead this is conditional at the three places where we print debug messages. The idea is that debug UARTs can be implemented without this ifdef boilerplate so they look cleaner, alas the ifdef has to be somewhere.

2020-09-15ARM: 9004/1: debug: Split waituart to CTS and TXRDYLinus Walleij
This patch was triggered by a remark from Russell that introducing a call to the waituart (needed to fix debug prints on the Qualcomm platforms) was dangerous because in some cases this will involve waiting for a modem CTS (clear to send) signal, and debug messages would maybe not work on platforms with no modem connected to the UART port: they will just hang waiting for the modem to assert CTS and this might never happen. Looking through all UART debug drivers implementing the waituart macro I discovered that all users except two actually use this macro to check if the UART is ready for TX, let's call this TXRDY. Only two debug UART drivers actually check for CTS: - arch/arm/include/debug/8250.S - arch/arm/include/debug/tegra.S The former is very significant since the 8250 is possibly the most common UART on the planet. We have the following problem: the semantics of waituart are ambiguous making it dangerous to introduce the macro to debug code fixing debug prints for Qualcomm. To start to pry this problem apart, this patch does the following: - Convert all debug UART drivers to define two macros: - waituartcts with the clear semantic to wait for CTS to be asserted - waituarttxrdy with the clear semantic to wait for the TX capability of the UART to be ready - When doing this take care to assign the right function to each drivers macro, so they now do exactly the above. - Update the three sites in the kernel invoking the waituart macro to call waituartcts/waituarttxrdy in sequence, so that the functional impact on the kernel should be zero. After this we can start to change the code sites using this code to do the right thing.

2020-09-15ARM: 9003/1: uncompress: Delete unused debug macrosLinus Walleij
The debug macros debug_reloc_start and debug_reloc_end were rendered unused in commit 6d7d0ae51574943bf571d269da3243257a2d15db "ARM: 6750/1: improvements to compressed/head.S". Later on a different debug macro named dbgkc was introduced in commit f3c899927e19d1be39818145efc39ea27b8efc69 "ARM: 8786/1: Debug kernel copy by printing". Delete the dead debug code.

This is commit fdfeff0f9e3d ("arm64: hw_breakpoint: Handle inexact watchpoint addresses") but ported to arm32, which has the same problem. This problem was found by Android CTS tests, notably the "watchpoint_imprecise" test [1]. I tested locally against a copycat (simplified) version of the test though.

2020-09-14ARM: dts: hisilicon: Fix SP805 clocksAndre Przywara
The SP805 DT binding requires two clocks to be specified, but Hisilicon platform DTs currently only specify one clock. In practice, Linux would pick a clock named "apb_pclk" for the bus clock, and the Linux and U-Boot SP805 driver would use the first clock to derive the actual watchdog counter frequency. Since currently both are the very same clock, we can just double the clock reference, and add the correct clock-names, to match the binding.

2020-09-14ARM: dts: hisilicon: Fix SP804 usersAndre Przywara
The SP804 binding only specifies one or three clocks, but does not allow just two clocks. The HiSi 3620 .dtsi specified two clocks for the two timers, plus gave one "apb_pclk" clock-name to appease the primecell bus driver. Extend the clocks by duplicating the first clock to the end of the clock list, and add two dummy clock-names to make the primecell driver happy. I don't know what the real APB clock for the IP is, but with the current DT the first timer clock was used for that, so this change keeps the current status.

Update the Integrator defconfig to the changes from the recent kernel cycles and especially the v5.9-rc1 changes. - Move options around as a result of Kconfig changes. - Drop the ZBOOT_ROM* stuff that doesn't exist anymore. - Add the syscon LEDs as used on the board for heartbeat and MMC traffic indication. - Add fixed voltage regulator support, this is used by the MMC controller for card voltage. - Select CONFIG_DRM_DISPLAY_CONNECTOR=y, the CONFIG_DRM_SIMPLE_BRIDGE was renamed when renaming the driver, but the simple bridge requires another bridge, the display connector bridge, in order to work, so this is required to have graphics working properly in kernel v5.9-rc1+ Link: https://lore.kernel.org/r/20200901082558.80388-1-linus.walleij@linaro.org Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net>

https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into arm/soc Samsung S3C24xx and S3C64xx machine code cleanup for v5.10 Big cleanup for the Samsung S3C24xx and S3C64xx platforms, although it also touches files shared with S5Pv210 and Exynos. This is mostly Arnd Bergmann work which Krzysztof Kozlowski took over, rebased and polished. The goal is to cleanup, merge and finally make the Samsung S3C24xx and S3C64xx architectures multiplatform. The multiplatform did not happen yet here - just cleaning up and merging into one arch/arm/mach-s3c directory. However this is step forward for multiplatform or at least to keep this code still maintainable. This pulls also branch with changes for Samsung SoC sound drivers from broonie/sound because the cleanups there were part of this series and all further patches depend on them. * tag 'samsung-soc-s3c-5.10' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: (62 commits) ARM: s3c: Avoid naming clash of S3C24xx and S3C64xx timer setup ARM: s3c: Cleanup from old plat-samsung include ARM: s3c: make headers local if possible ARM: s3c: move into a common directory ARM: s3c24xx: stop including mach/hardware.h from mach/io.h cpufreq: s3c24xx: move low-level clk reg access into platform code cpufreq: s3c2412: use global s3c2412_cpufreq_setrefresh ARM: s3c: remove cpufreq header dependencies cpufreq: s3c24xx: split out registers fbdev: s3c2410fb: remove mach header dependency ARM: s3c24xx: bast: avoid irq_desc array usage ARM: s3c24xx: spi: avoid hardcoding fiq number in driver ARM: s3c24xx: include mach/irqs.h where needed ARM: s3c24xx: move s3cmci pinctrl handling into board files ARM: s3c24xx: move iis pinctrl config into boards ARM: s3c24xx: move spi fiq handler into platform ARM: s3c: adc: move header to linux/soc/samsung ARM: s3c24xx: move irqchip driver back into platform ARM: s3c24xx: move regs-spi.h into spi driver ARM: s3c64xx: remove mach/hardware.h ...

2020-09-13ARM: Allow IPIs to be handled as normal interruptsMarc Zyngier
In order to deal with IPIs as normal interrupts, let's add a new way to register them with the architecture code. set_smp_ipi_range() takes a range of interrupts, and allows the arch code to request them as if the were normal interrupts. A standard handler is then called by the core IRQ code to deal with the IPI. This means that we don't need to call irq_enter/irq_exit, and that we don't need to deal with set_irq_regs either. So let's move the dispatcher into its own function, and leave handle_IPI() as a compatibility function. On the sending side, let's make use of ipi_send_mask, which already exists for this purpose. One of the major difference is that we end up, in some cases (such as when performing IRQ time accounting on the scheduler IPI), end up with nested irq_enter()/irq_exit() pairs. Other than the (relatively small) overhead, there should be no consequences to it (these pairs are designed to nest correctly, and the accounting shouldn't be off).
