2016-07-01phy: miphy28lp: Inform the reset framework that our reset line may be sharedLee Jones1-1/+2
On the STiH410 B2120 development board the MiPHY28lp shares its reset line with the Synopsys DWC3 SuperSpeed (SS) USB 3.0 Dual-Role-Device (DRD). New functionality in the reset subsystems forces consumers to be explicit when requesting shared/exclusive reset lines.

2015-12-03phy: miphy28lp: add missing of_node_putJulia Lawall1-5/+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>

The phy_ops variables are never modified after initialized in these drivers, so make them const. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Patrice Chotard <patrice.chotard@st.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

2015-03-04phy: miphy28lp: Avoid calling of_get_child_count() multiple timesAxel Lin1-5/+6
Currently, of_get_child_count() is called in each iteration of the for loop in miphy28lp_xlate(). This patch stores the return value of of_get_child_count() in miphy_dev->nphys and call of_get_child_count() once in miphy28lp_probe().

2015-01-21phy: miphy28lp: Pass sysconfig register offsets via syscfg dt property.Gabriel FERNANDEZ1-29/+32
Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161, update the miphy28lp 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 miphy28lp. This change then also aligns us to how other platforms such as keystone and bcm7445 pass there syscon offsets via DT. I have updated the miphy28lp phy driver same way as Peter's implementation.

2014-11-12phy: miphy28lp: Add SSC support for PCIEGabriel FERNANDEZ1-0/+44
SSC is the technique of modulating the operating frequency of a signal slightly to spread its radiated emissions over a range of frequencies. This reduction in the maximum emission for a given frequency helps meet radiated emission requirements. These settings are applicable for PCIE with Internal clock.
