* ARM: pxa: Transition pxa25x, pxa27x, pxa3xx to clk frameworkRobert Jarzmik2015-05-121-86/+0Star
| | | | | | | | | | | | | Transition the PXA25x, PXA27x and PXA3xx CPUs to the clock framework. This transition still enables legacy platforms to run without device tree as before, ie relying on platform data encoded in board specific files. This is the last step of clock framework transition for pxa platforms. It was tested on lubbock (pxa25x), mioa701 (pxa27x) and zylonite (pxa3xx).

* ARM: Consolidate clks_register() and similarRussell King2010-02-121-8/+0Star
| | | | | | | | | | | | | 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: make second argument of clk_add_alias a name instead of the deviceDmitry Eremin-Solenikov2009-03-191-2/+2
| | | | | | | | | | clk_add_alias is commonly called for platform devices that are not yet registered in the device tree. Thus the clock alias is associated with NULL device name. Fix this by passing the device name instead of just device pointer. Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Eric Miao <eric.miao@marvell.com>

* / [ARM] pxa: allow clk aliasesRussell King2008-07-091-0/+3
|/ | | | | | | | | We need to support more than one name+device for a struct clk for a small number of peripherals. We do this by re-using struct clk alias to another struct clk - IOW, if we find that the entry we're using is an alias, we return the aliased entry not the one we found.

* [ARM] pxa: separate GPIOs and their mode definitions to pxa2xx-gpio.heric miao2008-04-191-0/+1
| | | | | | | | | | | | | two reasons: 1. GPIO namings and their mode definitions are conceptually not part of the PXA register definitions 2. this is actually a temporary move in the transition of PXA2xx to use MFP-alike APIs (as what PXA3xx is now doing), so that legacy code will still work and new code can be added in step by step Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
