Thanx for your ACK.
I didn't look carefully at the others, but the dwc3-core patch (4/32)
definitely seemed wrong.
I don't find any wrong in the code.
Really ? Look more carefuly
static int dwc3_probe(struct platform_device *pdev)
{
struct device *dev = &pdev->dev;
struct dwc3_platform_data *pdata = dev_get_platdata(dev);
struct device_node *node = dev->of_node;
struct resource *res;
struct dwc3 *dwc;
int ret;
void __iomem *regs;
void *mem;
mem = devm_kzalloc(dev, sizeof(*dwc) + DWC3_ALIGN_MASK,
GFP_KERNEL);
if (!mem)
return -ENOMEM;
dwc = PTR_ALIGN(mem, DWC3_ALIGN_MASK + 1);
dwc->mem = mem;
dwc->dev = dev;
res = platform_get_resource(pdev, IORESOURCE_IRQ, 0);
if (!res) {
dev_err(dev, "missing IRQ\n");
return -ENODEV;
}
dwc->xhci_resources[1].start = res->start;
dwc->xhci_resources[1].end = res->end;
dwc->xhci_resources[1].flags = res->flags;
dwc->xhci_resources[1].name = res->name;
res = platform_get_resource(pdev, IORESOURCE_MEM, 0);
/*
* Request memory region but exclude xHCI regs,
* since it will be requested by the xhci-plat driver.
*/
regs = devm_ioremap_resource(dev, res);
because you moved this call here...
if (IS_ERR(regs))
return PTR_ERR(regs);
dwc->xhci_resources[0].start = res->start;
dwc->xhci_resources[0].end = dwc->xhci_resources[0].start +
DWC3_XHCI_REGS_END;
dwc->xhci_resources[0].flags = res->flags;
dwc->xhci_resources[0].name = res->name;
res->start += DWC3_GLOBALS_REGS_START;
... before doing this, you're now ioremapping the entire space
*INCLUDING* the XHCI address space, which means that you have just
broken every single platform using this driver in host mode.
In that case, i will drop this patch.
Is other patches are fine except #04/32 patch..?
Can i add you Ack..? And based on which tree i need to generate the patches.?
I rebased all these patches on [1] of master branch.
