This is SoC specific, not board specific, so you could check for "fsl,p2020-esdhc" for example. 1010 and 2020-rev1 would need proper compatibles as well. > For eSDHC, after suspending, the power of esdhc controller will shutdown, we > need to save the value of some registers before suspending, wich will used to > restore the context after resuming. > For eSDHC, the bit DCR[DMA__AHB2MAG_IRQ_BYPASS] can't be set automatically, > so we need to set it manually If this is true for all revisions (be careful about the imx users), you don't need properties, but could simply set it. -- Pengutronix e.K. | Wolfram Sang | Industrial Linux Solutions | http://www.pengutronix.de/ |
