ARM: imx6: gpc: always enable PU domain if CONFIG_PM is not set

2015-07-08T14:52:08+00:00

If CONFIG_PM is not set the PU power domain needs to be enabled always, otherwise there are two failure scenarios which will hang the system if one of the devices in the PU domain is accessed. 1. New DTs (4.1+) drop the "always-on" property from the PU regulator, so if it isn't properly enabled by the GPC code it will be disabled at the end of boot. 2. If the bootloader already disabled the PU domain the GPC explicitly needs to enable it again, even if the kernel doesn't do any power management. This is a bit hypothetical, as it requires to boot a mainline kernel on a downstream bootloader, as no mainline bootloader disables the PM domains.

genalloc: rename dev_get_gen_pool() to gen_pool_get()

2015-07-01T02:45:01+00:00

To be consistent with other genalloc interface namings, rename dev_get_gen_pool() to gen_pool_get(). The original omitted "dev_" prefix is removed, since it points to argument type of the function, and so it does not bring any useful information.

ARM: imx: imx7d requires anatop

2015-06-03T06:52:31+00:00

Like i.MX6, the i.MX7 code calls into the anatop driver, which fails if that is disabled: arch/arm/mach-imx/built-in.o: In function `imx7d_init_machine': arch/arm/mach-imx/mach-imx7d.c:24: undefined reference to `imx_anatop_init' arch/arm/mach-imx/built-in.o: In function `imx7d_init_irq': arch/arm/mach-imx/mach-imx7d.c:29: undefined reference to `imx_init_revision_from_anatop' This patch ensures that for an imx7-only build, we still get anatop built-in, matching what we do for imx6. We also need to select HAVE_IMX_MMDC, as that is needed by the anatop code. Signed-off-by: Arnd Bergmann Signed-off-by: Shawn Guo
