From: Vasily Khoruzhick Date: Thu, 14 Jun 2018 06:19:34 +0000 (-0700) Subject: usb: sunxi: access ahb_reset0_cfg in CCM using its offset X-Git-Tag: v2018.07-rc2~47^2 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=b9f34757db5dcde9ccfa6ce35705b025bc4843fc;p=oweals%2Fu-boot.git usb: sunxi: access ahb_reset0_cfg in CCM using its offset struct sunxi_ccm_reg doesn't have ahb_reset0_cfg on sun4i and sun5i, thus compilation fails with: drivers/usb/host/ohci-sunxi.c:96:26: error: 'struct sunxi_ccm_reg' has no member named 'ahb_reset0_cfg' Access this reg using its offset to fix this issue. Fixes commit 1ed9c1118 ("usb: sunxi: ehci: get rid of ifdefs") and commit 56830cee3 ("usb: sunxi: ohci: get rid of ifdefs") Signed-off-by: Vasily Khoruzhick --- diff --git a/drivers/usb/host/ehci-sunxi.c b/drivers/usb/host/ehci-sunxi.c index 35fbe03331..97d06d5975 100644 --- a/drivers/usb/host/ehci-sunxi.c +++ b/drivers/usb/host/ehci-sunxi.c @@ -22,14 +22,19 @@ #define AHB_CLK_DIST 1 #endif +#define SUN6I_AHB_RESET0_CFG_OFFSET 0x2c0 +#define SUN9I_AHB_RESET0_CFG_OFFSET 0x5a0 + struct ehci_sunxi_cfg { bool has_reset;
