git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into arm/soc i.MX SoC update for 5.5: - Add arm64 Kconfig option for the NXP S32 platform. - Drop imx_anatop_usb_chrg_detect_disable() function which becomes unneeded, since all the necessary charger setup is done by the USB PHY driver now. - Add serial number support for i.MX6/7 SoCs by reading 64-bit SoC unique ID from OCOTP block. - Replace i.MX machine specific coherency exit implementation using the generic v7_exit_coherency_flush() function. * tag 'imx-soc-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: ARM: imx: use generic function to exit coherency ARM: imx: Add serial number support for i.MX6/7 SoCs ARM: imx: Drop imx_anatop_usb_chrg_detect_disable() arm64: Introduce config for S32 Link: https://lore.kernel.org/r/20191105150315.15477-2-shawnguo@kernel.org Signed-off-by: Olof Johansson <olof@lixom.net>

2019-10-29ARM: tegra: Use WFE for power-gating on Tegra30Dmitry Osipenko2-3/+20
Turned out that WFI doesn't work reliably on Tegra30 as a trigger for the power-gating, it causes CPU hang under some circumstances like having memory controller running of PLLP. The TRM doc states that WFI should be used for the Big-Little "Cluster Switch", while WFE for the power-gating. Hence let's use the WFE for CPU0 power-gating, like it is done for the power-gating of a secondary cores. This fixes CPU hang after entering LP2 with memory running off PLLP.

We want to do this in small steps for the pwrdm_set_logic_retst() changes so we can identify the domain in case of unexpected issues - A series of PM changes to configure voltage controller for droid4. Eventually the voltage controller configuration should use device tree, but we want to get things working first.

2019-10-19ARM: OMAP2+: Configure voltage controller for cpcap to low-speedTony Lindgren2-6/+14
Looks like the i2c timings in high-speed mode do not work properly to allow us to clear I2C_DISABLE bits for PRM_VOLTCTRL register and the device reboots if I2C_DISABLE bits are cleared. Let's configure the voltage controller i2c for low-speed mode as done in the Motorola Mapphone Android Linux kernel. This saves us about 7mW of power during retention compared to the high-speed values. Let's also change the low-speed warning to pr_info about relying on the bootloader configured low-speed values like we currently do.

2019-10-17ARM: bcm: include local platsmp.h for bcm2836_smp_opsBen Dooks1-0/+2
Include platsmp.h for the definition of bcm2836_smp_ops to fix the following warning: arch/arm/mach-bcm/platsmp.c:334:29: warning: symbol 'bcm2836_smp_ops' was not declared. Should it be static?

2019-10-16ARM: OMAP2+: Simplify code for clkdm_clock_enable and disableTony Lindgren1-58/+20
We can make clkdm_clk_enable() usable for clkdm_hwmod_enable() by dropping the unused clock check, and drop _clkdm_clk_hwmod_enable(). And we can make clkdm_hwmod_disable() call clkdm_hwmod_disable() and drop the duplicate code in clkdm_hwmod_disable().

2019-10-16ARM: OMAP2+: Drop unused enable_wakeup and disable_wakeupTony Lindgren2-100/+0
We're only using static _enable_wakeup(), the others have no callers. Signed-off-by: Tony Lindgren <tony@atomide.com>
2019-10-16ARM: OMAP2+: Initialize voltage controller for omap4Tony Lindgren1-0/+29
We're missing initializing the PRM_VOLTCTRL register for voltage controller. Let's add omap4_vc_init_pmic_signaling() similar to what we have for omap3 and enable voltage control for retention. This brings down droid4 power consumption with mainline kernel to somewhere between 40 and 50mW from about 70 to 80 mW for the whole device when running idle with LCD and backlight off, WLAN connected, and USB and modem modules unloaded. Mostly just rmmod of omap2430, ohci-platform and phy-mapphone-mdm6600 are needed to idle USB and shut down the modem. And after that measuring idle power consumption can be done with reading sysfs entry periodically for /sys/class/power_supply/battery/power_avg. Then rmmod of phy-cpcap-usb will save few more mW, but will disable the debug UART. Note that sometimes CM_L4PER_UART1_CLKCTRL at 0x4a009540 does not idle properly after unloading of phy-mapphone-mdm6600.

2019-10-16ARM: OMAP2+: Allow core oswr for omap4Tony Lindgren1-12/+2
Commit f74297dd9354 ("ARM: OMAP2+: Make sure LOGICRETSTATE bits are not cleared") disabled oswr (open switch retention) for per and core domains as various GPIO related issues were noticed if the bootloader had configured the bits for LOGICRETSTATE for per and core domains. With the recent gpio-omap fixes, mostly related to commit e6818d29ea15 ("gpio: gpio-omap: configure edge detection for level IRQs for idle wakeup"), things now behave for enabling core oswr for omap4.
