* phy: miphy365x: add missing of_node_putJulia Lawall2015-12-031-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | for_each_child_of_node performs an of_node_get on each iteration, so a return from the middle of the loop requires an of_node_put. A simplified version of the semantic patch that finds this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression root,e; local idexpression child; @@ for_each_child_of_node(root, child) { ... when != of_node_put(child) when != e = child ( return child; | * return ...; ) ... } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

| * phy: miphy365x: Use the generic phy type constants in dt-bindings/phy/phy.hPeter Griffin2015-04-031-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now there are generic phy type constants declared in phy.h, migrate over to using them rather than defining our own. This change has been done as one atomic commit to be bisectable. Note: The values of the defines are the same, so there is no ABI breakage with this patch.

* | phy: miphy365x: Avoid calling of_get_child_count() multiple timesAxel Lin2015-03-041-5/+6
|/ | | | | | | | | Currently, of_get_child_count() is called in each iteration of the for loop in miphy365x_xlate(). This patch stores the return value of of_get_child_count() in miphy_dev->nphys and call of_get_child_count() once in miphy365x_probe().

* phy: miphy365x: Pass sysconfig register offsets via syscfg dt property.Peter Griffin2015-01-111-19/+10
| | | | | | | | | | | | | | | | | | | | Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161, update the miphy365 phy driver to access sysconfig register offsets via syscfg dt property. This is because the reg property should not be mixing address spaces like it does currently for miphy365. This change then also aligns us to how other platforms such as keystone and bcm7445 pass there syscon offsets via DT. This patch breaks DT compatibility, but this platform is considered WIP, and is only used by a few developers who are upstreaming support for it. This change has been done as a single atomic commit to ensure it is bisectable.

| | | | | | | | | | | | | | | We index the RX/TX speed select values in the following way: rx_tx_spd[miphy_phy->sata_gen]; However rx_tx_spd[] starts at index zero and the SATA_GENx's start at one. In this patch we pad out the first element in rx_tx_spd[] in an attempt to realign the values.
