2019-12-17ARM: defconfig: u8500: activate cpufreqLinus Walleij
This activates the device tree-based cpufreq driver that Ux500 is using and enables the schedutil and ondemand governors with schedutil as default. This works fine in the setups I have tested.

2019-07-23ARM: defconfig: u8500: Add new driversLinus Walleij
This enables the new or updates driver options for U8500 that got merged into v5.3-rc1: - CMA, MCDE driver, LIMA driver and the Samsung S6D16D0 driver enabled by default bringing up the new graphics support. Include the LOGO so we can see when the graphics are live. - We use the IIO hwmon bridge for reflecting temperature in the system. - Set MUSB to PIO mode as this is the one working most stable for the time being. - HWSPINLOCK needs to be set to get the hardware semaphore driver to compile and link properly.

2019-06-19ARM: configs: Remove useless UEVENT_HELPER_PATHKrzysztof Kozlowski
Remove the CONFIG_UEVENT_HELPER_PATH because: 1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was made default to 'n', 2. It is not recommended (help message: "This should not be used today [...] creates a high system load") and was kept only for ancient userland, 3. Certain userland specifically requests it to be disabled (systemd README: "Legacy hotplug slows down the system and confuses udev").

In order to utilise all of the memory located on ux500 based devices we have to enable HIGHMEM.

So is the AB5500 driver. - CPU_IDLE selected explicitly. - LP5521 Kconfig has been moved around. - AB8500 core is default-selected, as is the AB8500 USB transciever. - The battery and charging management drivers for the AB8500 are not selected again. - Select the crypto devices that have been shaped up to work properly.

2012-08-23ARM: ux500: don't select LEDS_GPIO for snowballArnd Bergmann
Using 'select' in Kconfig is hard, a platform cannot just enable a driver without also making sure that its subsystem is there. Also, there is no actual code dependency between the platform and the gpio leds driver. Without this patch, building without LEDS_CLASS esults in: drivers/built-in.o: In function `create_gpio_led.part.2': governor_userspace.c:(.devinit.text+0x5a58): undefined reference to `led_classdev_register' drivers/built-in.o: In function `gpio_led_remove': governor_userspace.c:(.devexit.text+0x6b8): undefined reference to `led_classdev_unregister' This reverts 8733f53c6 "ARM: ux500: Kconfig: Compile in leds-gpio support for Snowball" that introduced the regression and did not provide a helpful explanation. In order to leave the GPIO LED code still present in normal builds, this also enables the symbol in u8500_defconfig, in addition to the other LED drivers that are already selected there.
