powerpc/83xx: gianfar_ptp: select 1588 clock source through dts file
Currently IEEE 1588 timer reference clock source is determined through hard-coded value in gianfar_ptp driver. This patch allows to select ptp clock source by means of device tree file node. For instance: fsl,cksel = <0>; for using external (TSEC_TMR_CLK input) high precision timer reference clock. Other acceptable values: <1> : eTSEC system clock <2> : eTSEC1 transmit clock <3> : RTC clock input When this attribute isn't used, eTSEC system clock will serve as IEEE 1588 timer reference clock.
