2014-02-06ARM: qcom: Split Qualcomm support into legacy and multiplatformKumar Gala1-6/+0
Introduce a new mach-qcom that will support SoCs that intend to be multiplatform compatible while keeping mach-msm to legacy SoC/board support that will not transition over to multiplatform. As part of this, we move support for MSM8X60, MSM8960 and MSM8974 over to mach-qcom. Signed-off-by: Kumar Gala <galak@codeaurora.org>
2014-02-04clocksource: qcom: Move clocksource code out of mach-msmKumar Gala1-1/+0
We intend to share the clocksource code for MSM platforms between legacy and multiplatform supported qcom SoCs. Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Kumar Gala <galak@codeaurora.org>
2014-02-04ARM: msm: kill off hotplug.cKumar Gala1-1/+0
Right now hotplug.c only really implements msm_cpu_die as a wfi. Just move that implementation into platsmp.c. At the same time we use the existing wfi() instead of inline asm. Signed-off-by: Kumar Gala <galak@codeaurora.org>

2014-01-09ARM: msm: Only build timer.c if requiredStephen Boyd1-1/+1
The MSM timer is only used on MSM devices that don't have the architected timers. Introduce a hidden Kconfig option for this driver so that we don't build it on the platforms that don't need it. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Olof Johansson <olof@lixom.net>
2014-01-09ARM: msm: Only build clock.c on proc_comm based platformsStephen Boyd1-1/+1
The functionality provided by clock.c in mach-msm is only needed on proc_comm based platforms. Only build the file if proc_comm is enabled. This prevents compile failures for platforms that are part of the multi-platform kernel. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Olof Johansson <olof@lixom.net>

2013-08-06ARM: msm: Only compile io.c on platforms that use itStephen Boyd1-4/+4
Only the non-dt based MSM platforms need to map memory from their machine descriptor. Unfortunately it is always compiled if ARCH_MSM=y and the file also has mach/ includes in it. Since dt-based MSM platforms aren't actually using anything in this file just compile io.c on the non-dt based MSM platforms. This allows the dt-based platforms to participate in the multi-platform kernel. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
2013-08-06ARM: msm: Remove devices-iommu.cStephen Boyd1-1/+0
The iommu devices are registered in software, when they should really be part of the DT. Since we don't currently have DT bindings in place for the MSM iommu driver just remove this file for the time being. This is not removing any functionality anyway because these devices aren't probing today due to missing clocks.

2013-06-24ARM: msm: Migrate to common clock frameworkStephen Boyd1-1/+0
Move the existing clock code in mach-msm to the common clock framework. We lose our capability to set the rate of and enable a clock through debugfs. This is ok though because the debugfs features are mainly used for testing and development of new clock code. To maintain compatibility with the original MSM clock code we make a wrapper for clk_reset() that calls the struct msm_clk specific reset function. This is necessary for the usb and sdcc devices on MSM until a better suited API is made available.

In the near future we'll be moving clock-pcom to a platform driver, in which case these two users of clk_get() in mach-msm need to be updated. Have board-trout-panel.c make the proc_comm call directly so that we don't have to port this board specific code to the driver right now and reorder the initcall order of dma.c so that it initializes after the clock driver probes but before any drivers use dma APIs.

From David Brown: These patches migrate both the 8660 and 8960 targets on msm to be devicetree only. This also sets most of the frame in place necessary to build both targets into the same image. There's a couple of cleanups in here that are kept in this series because they are intimately tied to the changes necessary to support the devicetree conversions.

2011-02-28msm: clock: Remove references to clk_ops_pcomStephen Boyd1-5/+1
Not all devices use proc_comm and determining if a clock is local vs. remote is fragile when done by comparing clk_ops pointers. Instead, implement an is_local() function for all clk_ops to determine if the clock is local. Doing this allows us to remove the last references to clk_ops_pcom from clock.c and compile it for targets with CONFIG_MSM_PROC_COMM=n. We don't need to set the clk_ops at runtime until 7x30 local clock detection comes in. Right now it's just complicating things so just set the ops pointer statically.

2011-01-07msm: Secure Channel Manager (SCM) supportStephen Boyd1-0/+1
SCM is the protocol used to communicate between the secure and non-secure code executing on the applications processor. The non-secure side uses a physically contiguous buffer to pass information to the secure side; where the buffer conforms to a format that is agreed upon by both sides. The use of a buffer allows multiple pending requests to be in flight on the secure side. It also benefits use cases where the command or response buffer contains large chunks of data.

2010-10-06msm: add gpiomux api for gpio multiplex & configuration.Gregory Bean1-0/+3
Add the 'gpiomux' api, which addresses the following shortcomings of existing tlmm api: - gpio power-collapse, which is managed by a peripheral processor on other targets, must be managed by the application processor on the 8x60. - The enable/disable flag of the legacy gpio_tlmm_config api is not applicable on the 8x60, and causes confusion. - The gpio 'direction' bits are meaningless for all func_sel configurations except for generic-gpio mode (func_sel 0), in which case the gpio_direction_* functions should be used. Having these bits in the tlmm api leads to confusion and misuse of the gpiolib api, and they have been removed in gpiomux. - The functional api of the legacy system ran contrary to the typical use-case, which is a single massive configuration at boot. Rather than forcing hundreds of 'config' function calls, the new api allows data to be configured with a single table. gpiomux_get and gpiomux_put are meant to be called automatically when gpio_request and gpio_free are called, giving automatic gpiomux/tlmm control to those drivers/lines with simple power profiles - in the simplest cases, an entry in the gpiomux table and the correct usage of gpiolib is all that is required to get proper gpio power control.
