* ARM: imx: provide v7_cpu_resume() only on ARM_CPU_SUSPEND=yAhmad Fatoum2020-04-171-0/+2
| | | | | | | | | | | | | | | | | | | | | 512a928affd5 ("ARM: imx: build v7_cpu_resume() unconditionally") introduced an unintended linker error for i.MX6 configurations that have ARM_CPU_SUSPEND=n which can happen if neither CONFIG_PM, CONFIG_CPU_IDLE, nor ARM_PSCI_FW are selected. Fix this by having v7_cpu_resume() compiled only when cpu_resume() it calls is available as well. The C declaration for the function remains unguarded to avoid future code inadvertently using a stub and introducing a regression to the bug the original commit fixed.

* | ARM: imx: build v7_cpu_resume() unconditionallyAhmad Fatoum2020-02-134-16/+28
|/ | | | | | | | | | | | | | | | | | | | | | | | This function is not only needed by the platform suspend code, but is also reused as the CPU resume function when the ARM cores can be powered down completely in deep idle, which is the case on i.MX6SX and i.MX6UL(L). Providing the static inline stub whenever CONFIG_SUSPEND is disabled means that those platforms will hang on resume from cpuidle if suspend is disabled. So there are two problems: - The static inline stub masks the linker error - The function is not available where needed Fix both by just building the function unconditionally, when CONFIG_SOC_IMX6 is enabled. The actual code is three instructions long, so it's arguably ok to just leave it in for all i.MX6 kernel configurations.

If regmap fetch fails then a message is printed but regmap_read is called anyway and the system crashes. Failing to lookup ocotp regmap shouldn't be a fatal boot error so check that the pointer is valid. Only side-effect of ocotp lookup failure now is that serial number will be reported as all-zeros which is acceptable.

|/ | | | | | | | | | | | | | | | Commit 99e98d3fb100 ("cpuidle: Consolidate disabled state checks") overlooked the fact that the imx6q and tegra20 cpuidle drivers use the "disabled" field in struct cpuidle_state for quirks which trigger after the initialization of cpuidle, so reading the initial value of that field is not sufficient for those drivers. In order to allow them to implement the quirks without using the "disabled" field in struct cpuidle_state, introduce a new helper function and modify them to use it.

* ARM: imx: stop adjusting ar8031 phy tx delayAndré Draszik2019-08-241-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent changes to the Atheros at803x driver cause the approach taken here to stop working because commit 6d4cd041f0af ("net: phy: at803x: disable delay only for RGMII mode") and commit cd28d1d6e52e ("net: phy: at803x: Disable phy delay for RGMII mode") fix the AR8031 driver to configure the phy's (RX/TX) delays as per the 'phy-mode' in the device tree. In particular, the phy tx (and rx) delays are updated again as per the 'phy-mode' *after* the code in here runs. Things worked before above commits, because the AR8031 comes out of reset with RX delay enabled, and the at803x driver didn't touch the delay configuration at all when "rgmii" mode was selected. It appears the code in here tries to make device trees work that incorrectly specify "rgmii", but that can't work any more and it is imperative since above commits to have the phy-mode configured correctly in the device tree. I suspect there are a few imx7d based boards using the ar8031 phy and phy-mode = "rgmii", but given I don't know which ones exactly, I am not in a position to update the respective device trees. Hence this patch is simply removing the superfluous code from the imx7d initialisation. An alternative could be to add a warning instead, but that would penalize all boards that have been updated already.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 1e434b703248 ("ARM: imx: update the cpu power up timing setting on i.mx6sx") some characters loss is noticed on i.MX6ULL UART as reported by Christoph Niedermaier. The intention of such commit was to increase the SW2ISO field for i.MX6SX only, but since cpuidle-imx6sx is also used on i.MX6UL/i.MX6ULL this caused unintended side effects on other SoCs. Fix this problem by keeping the original SW2ISO value for i.MX6UL/i.MX6ULL and only increase SW2ISO in the i.MX6SX case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current cpuidle implementation for i.MX6q, the CPU that sets 'WAIT_UNCLOCKED' and the CPU that returns to 'WAIT_CLOCKED' are always the same. While the CPU that sets 'WAIT_UNCLOCKED' is in IDLE state of "WAIT", if the other CPU wakes up and enters IDLE state of "WFI" istead of "WAIT", this CPU can not wake up at expired time. Because, in the case of "WFI", the CPU must be waked up by the local timer interrupt. But, while 'WAIT_UNCLOCKED' is set, the local timer is stopped, when all CPUs execute "wfi" instruction. As a result, the local timer interrupt is not fired. In this situation, this CPU will wake up by IRQ different from local timer. (e.g. broacast timer) So, this fix changes CPU to return to 'WAIT_CLOCKED'.

Cleanups continue on the older mach-davinci and mach-pxa platform, to get them to be more like the modern ones. For pxa, we now remove the Raumfeld platform code as it now works with device tree based booting. i.MX adds a couple new features for the i.MX7ULP SoC Mediatek gains support for a new SoC: MT7629 is a new wireless router platform, following MT7623. Aside from those, there are the usual minor cleanups and bugfixes across several platforms" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (49 commits) MAINTAINERS: Update Ampere email address usb: ohci-da8xx: remove unused callbacks from platform data ARM: davinci: da830-evm: remove legacy usb helpers ARM: davinci: omapl138-hawk: remove legacy usb helpers usb: ohci-da8xx: add vbus and overcurrent gpios ARM: davinci: da830-evm: use gpio lookup entries for usb gpios ARM: davinci: omapl138-hawk: use gpio lookup entries for usb gpios usb: ohci-da8xx: add a helper pointer to &pdev->dev usb: ohci-da8xx: add a new line after local variables arm64: meson: enable g12a clock controller MAINTAINERS: Add entry for uDPU board ARM: davinci: da850-evm: use GPIO hogs instead of the legacy API arm: mediatek: add MT7629 smp bring up code Revert "ARM: mediatek: add MT7623a smp bringup code" dt-bindings: soc: fix typo of MT8173 power dt-bindings ARM: meson: remove COMMON_CLK_AMLOGIC selection arm64: meson: remove COMMON_CLK_AMLOGIC selection ARM: lpc32xx: remove platform data of ARM PL111 LCD controller ARM: lpc32xx: remove platform data of ARM PL180 SD/MMC controller ARM: lpc32xx: Use kmemdup to replace duplicating its implementation ...
