2016-06-28ARM: imx: rework mx27_pm_init() callArnd Bergmann1-0/+1
mx27_pm_init() uses its own initcall, unlike all of the other functions like it. Replacing the initcall with a .init_late() callback makes imx27 more like the others and lets us remove the last caller of cpu_is_mx27().

2016-04-25cpufreq: imx: Use generic platdev driverViresh Kumar1-10/+0
The cpufreq-dt-platdev driver supports creation of cpufreq-dt platform device now, reuse that and remove similar code from platform code. Note that the complete routine imx27_dt_init() is removed as of_platform_populate(NULL, of_default_bus_match_table, NULL, NULL); has same effect as a NULL .init_machine machine callback pointer.

2014-11-22ARM: imx: clean up machine mxc_arch_reset_init_dt reset initJingchang Lu1-3/+0
System restart mechanism has been changed with the introduction of "kernel restart handler call chain support". The imx2 watchdog based restart handler has been moved to the driver, and these restart can be removed from the machine layer. This patch cleans up the device tree version machine reset init with mxc_arch_reset_init_dt and removes corresponding .restart handler, for the .init_machine that can be handled by system default after removing the mxc_arch_reset_init_dt, the .init_machine is also removed.

2014-10-03cpufreq: cpu0: rename driver and internals to 'cpufreq_dt'Viresh Kumar1-1/+1
The naming convention of this driver was always under the scanner, people complained that it should have a more generic name than cpu0, as it manages all CPUs that are sharing clock lines. Also, in future it will be modified to support any number of clusters with separate clock/voltage lines. Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

2013-06-17ARM: imx: create mxc_arch_reset_init_dt() for DT bootShawn Guo1-2/+1
The mxc_arch_reset_init() uses static mapping and calls clk_get_sys() to get clock. It's suitable for non-DT boot but not for DT boot where dynamic mapping and of_clk_get() should be used instead. Create mxc_arch_reset_init_dt() as the DT variant of mxc_arch_reset_init(), and change DT platforms to use it. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-06-17ARM: imx: move clk_prepare() out from mxc_restart()Shawn Guo1-0/+3
It's inappropriate to call clk_prepare() in mxc_restart(), because the restart routine could be called in atomic context. Move clk_get() and clk_prepare() into mxc_arch_reset_init() and only have the atomic part clk_enable() be called in mxc_restart(). As a result, mxc_arch_reset_init() needs to be called after clk gets initialized. While there, it also changes printk(KERN_ERR ...) to pr_err() and adds __init annotation for mxc_arch_reset_init().

2012-12-24ARM: delete struct sys_timerStephen Warren1-10/+6
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-10-15ARM: imx: include hardware.h rather than mach/hardware.hShawn Guo1-1/+1
It moves a bunch of header files included in hardware.h and itself from mach-imx/include/mach to mach-imx, and updates users to include hardware.h rather than mach/hardware.h. The files in mach-imx/devices will need to include "../hardware.h".

2012-10-15i2c: imx: remove cpu_is_xxx by using platform_device_idShawn Guo1-2/+2
This is some amount of work left/forgot from device tree conversion. Instead of checking cpu_is_xxx to determine the controller type, the driver should use platform_device_id, which should match the device tree compatible string. The patch changes the driver to use platform_device_id rather than cpu_is_xxx to determine the controller type/version. It also updates the platform code and device tree source accordingly. As the result, mach/hardware.h inclusion gets removed from the driver.

Move irq_domain_add_legacy call from imx27-dt.c into avic init function and have the avic driver adopt irqdomain support for both DT and non-DT boot. Now avic init function calls irq_alloc_descs to get irq_base and adds a lenacy irqdomain with the irq_base, so that the mapping between avic irq and Linux irq number can be handled by irqdomain.

Move irq_domain_add_legacy call from imx*-dt.c into gpio driver and have the gpio driver adopt irqdomain support for both DT and non-DT boot. With all imx platform code converted from static gpio irq number computation to use run-time gpio_to_irq call, we can now use irq_alloc_descs and irqdomain support to dynamically get irq_base and have the mapping between gpio and irq number available without using virtual_irq_start and MXC_GPIO_IRQ_START.
