* ARM: mmp: let clk_disable() return immediately if clk is NULLMasahiro Yamada2017-03-301-0/+3
| | | | | | | | | | | In many of clk_disable() implementations, it is a no-op for a NULL pointer input, but this is one of the exceptions. Making it treewide consistent will allow clock consumers to call clk_disable() without NULL pointer check.

* ARM: mmp: make all header files localArnd Bergmann2015-12-011-1/+1
| | | | | | | | | | The mach/*.h headers are now inaccessible to any external code, so we can move them all into the mach-mmp directory itself and remove the subdirectories. A few headers are not used at all, so we remove them here. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
* ARM: pxa: add clk_set_rate()Haojian Zhuang2011-07-121-0/+15
| | | | | | | | Since there're mulitple clock rates in some device controllers, enable clk_set_rate() for this usage. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
* ARM: Consolidate clks_register() and similarRussell King2010-02-121-8/+0
| | | | | | | | | | | | | Most machine classes want some way to register a block of clk_lookup structures, and most do it by implementing a clks_register() type function which walks an array, or by open-coding a loop. Consolidate all this into clkdev_add_table().

* [ARM] pxa: add base support for Marvell's PXA168 processor lineEric Miao2009-03-231-0/+83
"""The MarvellĀ® PXA168 processor is the first in a family of application processors targeted at mass market opportunities in computing and consumer devices. It balances high computing and multimedia performance with low power consumption to support extended battery life, and includes a wealth of integrated peripherals to reduce overall BOM cost .... """ See http://www.marvell.com/featured/pxa168.jsp for more information. 1. Marvell Mohawk core is a hybrid of xscale3 and its own ARM core, there are many enhancements like instructions for flushing the whole D-cache, and so on 2. Clock reuses Russell's common clkdev, and added the basic support for UART1/2. 3. Devices are a bit different from the 'mach-pxa' way, the platform devices are now dynamically allocated only when necessary (i.e. when pxa_register_device() is called). Description for each device are stored in an array of 'struct pxa_device_desc'. Now that: a. this array of device description is marked with __initdata and can be freed up system is fully up b. which means board code has to add all needed devices early in his initializing function c. platform specific data can now be marked as __initdata since they are allocated and copied by platform_device_add_data() 4. only the basic UART1/2/3 are added, more devices will come later.
