ARM: keystone: config: fix build warning when CONFIG_DMADEVICES is not set

2014-01-31T23:03:53+00:00

Drop automatic selection of TI_EDMA from Keystone Kconfig file,
as it produces build warning in case if CONFIG_DMADEVICES is not set:

warning: (ARCH_KEYSTONE) selects TI_EDMA which has unmet direct dependencies (DMADEVICES && (ARCH_DAVINCI || ARCH_OMAP || ARCH_KEYSTONE))

Instead enable TI EDMA support from defconfig.

ARM: keystone: Avoid calling of_clk_init() twice

2013-12-16T21:03:36+00:00

With commit 4178bac4f {ARM: call of_clk_init from default time_init
handler}, of_clk_init() is always called on machines using default
time_init handler.

So drop the of_clk_init() from keystone code to avoid below
boot errors because of double call.

_of_pll_clk_init: error initializing pll mainpllclk
_of_pll_clk_init: error initializing pll papllclk
_of_pll_clk_init: error initializing pll ddr3apllclk
_of_pll_clk_init: error initializing pll ddr3bpllclk
_of_pll_clk_init: error initializing pll armpllclk

ARM: keystone: Make PM bus ready before populating platform devices

2013-12-16T21:03:36+00:00

Keystone PM bus makes use of generic PM clock core backend. Since
generic PM clock core uses platform bus notifiers to track events like
ADD_DEVICE/DEL_DEVICE and to fill clock lists per each device, we need
to initialise Keystone PM domains before the platform devices have been
created.

Hence, fix it by moving keystone_pm_runtime_init() before platform
devices have been populated.

ARM: keystone: enable DMA zone for LPAE

2013-12-16T21:03:36+00:00

Keystone II peripheral devices support 32-bit DMA and hence can access only
first 2GB of the memory address space. So set the platform dma_zone_size
to handle that case.

ARM: keystone: enable big endian support

2013-12-16T21:03:35+00:00

Keystone code is big endian compatible,
so mark it as one that supports big endian.

Note this patch just allows to select Big endian build
for ARCH_KEYSTONE, but it does not enable BE by default.

Merge tag 'devicetree-for-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

2013-11-12T07:52:17+00:00

Pull devicetree updates from Rob Herring:
"DeviceTree updates for 3.13. This is a bit larger pull request than
usual for this cycle with lots of clean-up.

- Cross arch clean-up and consolidation of early DT scanning code.
- Clean-up and removal of arch prom.h headers. Makes arch specific
prom.h optional on all but Sparc.
- Addition of interrupts-extended property for devices connected to
multiple interrupt controllers.
- Refactoring of DT interrupt parsing code in preparation for
deferred probe of interrupts.
- ARM cpu and cpu topology bindings documentation.
- Various DT vendor binding documentation updates"

ARM: keystone: fix PM domain initcall to be keystone only

2013-10-14T18:10:33+00:00

initcalls need to have platform specific checks so they are not run in
multi-platform builds.

ARM: keystone: Select TI_EDMA to be able to enable SPI driver

2013-10-10T23:52:18+00:00

Select the TI EDMA to be able to enable SPI driver on Keystone
SOCs. Keystone SOCs share the EDMA IP with other TI SOCs.

Note that EDMA support hasn't been added and tested yet for
Keystone SOC data(device tree), but building it, is harmless since
driver like SPI already takes care of supporting non-dma mode
in the absence of such data.

ARM: keystone: add PM domain support for clock management

2013-10-10T23:51:19+00:00

Add runtime PM core support to Keystone SOCs by using the pm_clk
infrastructure of the PM core. Patch is based on Kevin's pm_domain
work on DaVinci SOCs.

Keystone SOC doesn't have depedency to enable clocks in early
in the boot and hence the clock and PM domain initialisation is done
at subsys_init() level.
