QE: Move QE from arch/powerpc to drivers/soc

2015-12-22T23:12:56+00:00

ls1 has qe and ls1 has arm cpu. move qe from arch/powerpc to drivers/soc/fsl to adapt to powerpc and arm Signed-off-by: Zhao Qiang Signed-off-by: Scott Wood

QE: use subsys_initcall to init qe

2015-12-22T23:10:18+00:00

Use subsys_initcall to init qe to adapt ARM architecture. Remove qe_reset from PowerPC platform file. Signed-off-by: Zhao Qiang Signed-off-by: Scott Wood

QE/CPM: move muram management functions to qe_common

2015-12-22T23:10:18+00:00

QE and CPM have the same muram, they use the same management functions. Now QE support both ARM and PowerPC, it is necessary to move QE to "driver/soc", so move the muram management functions from cpm_common to qe_common for preparing to move QE code to "driver/soc" Signed-off-by: Zhao Qiang Signed-off-by: Scott Wood

irqdomain: Use irq_domain_get_of_node() instead of direct field access

2015-10-13T17:01:23+00:00

The struct irq_domain contains a "struct device_node *" field (of_node) that is almost the only link between the irqdomain and the device tree infrastructure. In order to prepare for the removal of that field, convert all users to use irq_domain_get_of_node() instead.

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help! Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu

genirq/irqdomain: Allow irq domain aliasing

2015-07-29T22:14:36+00:00

It is not uncommon (at least with the ARM stuff) to have a piece of hardware that implements different flavours of "interrupts". A typical example of this is the GICv3 ITS, which implements standard PCI/MSI support, but also some form of "generic MSI". So far, the PCI/MSI domain is registered using the ITS device_node, so that irq_find_host can return it. On the contrary, the raw MSI domain is not registered with an device_node, making it impossible to be looked up by another subsystem (obviously, using the same device_node twice would only result in confusion, as it is not defined which one irq_find_host would return). A solution to this is to "type" domains that may be aliasing, and to be able to lookup an device_node that matches a given type. For this, we introduce irq_find_matching_host() as a superset of irq_find_host: struct irq_domain *irq_find_matching_host(struct device_node *node, enum irq_domain_bus_token bus_token); where bus_token is the "type" we want to match the domain against (so far, only DOMAIN_BUS_ANY is defined). This result in some moderately invasive changes on the PPC side (which is the only user of the .match method). This has otherwise no functionnal change.

powerpc: Constify irq_domain_ops

powerpc: don't export static symbol

2015-04-01T03:23:18+00:00

The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // @r@ type T; identifier f; @@ static T f (...) { ... } @@ identifier r.f; declarer name EXPORT_SYMBOL; @@ -EXPORT_SYMBOL(f); // Furthermore, the function is never used, so its definition is dropped as well.

powerpc/qe: drop unused ucc_slow_poll_transmitter_now

2015-03-16T07:50:17+00:00
