usb: xhci: Add virt_to_phys() to support mapped platforms

2020-08-05T07:30:46Z

Some platforms, like MIPS Octeon, use mapped addresses (virtual address != physical address). On these platforms we need to make sure, that the local virtual addresses are converted to physical (DMA) addresses for the xHCI controller. This patch adds the missing virt_to_phys() calls, so that the correct addresses are used. Signed-off-by: Stefan Roese Reviewed-by: Bin Meng Tested-by: Bin Meng Cc: Bin Meng Cc: Marek Vasut

usb: usb-uclass.c: Drop le16_to_cpu() as values are already swapped

2020-08-05T07:30:46Z

These values are already swapped to CPU endianess, so swapping them again is a bug. Let's remove the swap here instead. Signed-off-by: Stefan Roese Reviewed-by: Bin Meng Tested-by: Bin Meng Cc: Bin Meng Cc: Marek Vasut

usb: xhci: xhci_mem_init: Use cpu_to_le64() and not xhci_writeq()

2020-08-05T07:30:46Z

xhci_writeq() makes the CPU->LE swapping only when addressing registers in the xHCI controller address range and not in the local memory (RAM). We need to use cpu_to_le64() here to ensure that the conversion is done correctly. Signed-off-by: Stefan Roese Reviewed-by: Bin Meng Tested-by: Bin Meng Cc: Bin Meng Cc: Marek Vasut

usb: xhci: Add missing endian conversions (cpu_to_leXX / leXX_to_cpu)

2020-08-05T07:30:46Z

While trying to use the U-Boot xHCI driver on the MIPS Octeon platform, which is big endian, I noticed that the driver is missing a few endian conversion calls. This patch adds these missing endian conversion calls. Signed-off-by: Stefan Roese Reviewed-by: Bin Meng Tested-by: Bin Meng Cc: Bin Meng Cc: Marek Vasut

usb: Drop dm.h header file

2020-08-04T02:19:54Z

This header file should not be included in other header files. Remove it and use a forward declaration instead. Also move the inline function out into a C file. We should not include C code in headers. Signed-off-by: Simon Glass

treewide: convert devfdt_get_addr() to dev_read_addr()

2020-07-25T20:46:57Z

When you enable CONFIG_OF_LIVE, you will end up with a lot of conversions. To generate this commit, I used coccinelle excluding drivers/core/, include/dm/, and test/ The semantic patch that makes this change is as follows: @@ expression dev; @@ -devfdt_get_addr(dev) +dev_read_addr(dev) Signed-off-by: Masahiro Yamada

treewide: convert (void *)devfdt_get_addr() to dev_read_addr_ptr()

2020-07-25T20:46:57Z

Use the _ptr suffixed variant instead of casting. Also, convert it to dev_read_addr_ptr(), which is safe to CONFIG_OF_LIVE. One curious part is an error check like follows in drivers/watchdog/omap_wdt.c: priv->regs = (struct wd_timer *)devfdt_get_addr(dev); if (!priv->regs) return -EINVAL; devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error. So, this code does not catch any error in DT parsing. dev_read_addr_ptr() returns NULL on error, so this error check will work. I generated this commit by the following command: $ find . -name .git -prune -o -name '*.[ch]' -type f -print | \ xargs sed -i -e 's/([^*)]*\*)devfdt_get_addr(/dev_read_addr_ptr(/' I manually fixed drivers/usb/host/ehci-mx6.c Signed-off-by: Masahiro Yamada
