Major differences are as follows. OMAP5 has one main interrupt and one misc interrupt Aegis has four main interrupts and one misc interrupt. Miscellanous Interrupt offsets are changed. UTMI OTG Control and Status Registers offsets are changed. DEBUG Configuration and Status Registers are changed. The main intend of the patch is to re-use the same wrapper driver for both OMAP5 and AM437x, by using the x_major in revision register and adjusting the offsets. This patch adds the register map offsets and adds offset variables in struct dwc3_omap to cache the offsets Signed-off-by: George Cherian --- drivers/usb/dwc3/dwc3-omap.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/drivers/usb/dwc3/dwc3-omap.c b/drivers/usb/dwc3/dwc3-omap.c index 34638b9..a354b4c 100644 --- a/drivers/usb/dwc3/dwc3-omap.c +++ b/drivers/usb/dwc3/dwc3-omap.c @@ -122,6 +122,12 @@ struct dwc3_omap { void __iomem *base; u32 utmi_otg_status; + u32 utmi_otg_offset; + u32 irqmisc_offset; + u32 irq_eoi_offset; + u32 debug_offset; + u32 irq0_offset; + u32 revision; u32 dma_status:1; }; -- 1.8.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
