Hi Andrew, Today's linux-next merge of the akpm tree got a conflict in drivers/ata/sata_mv.c between commit eee989902aab ("ARM: Orion: SATA: Add per channel clk/clkdev support") from the arm-soc tree and commit "ata/sata_mv: remove conditional compilation of clk code" from the akpm tree. I fixed it up (see below) and can carry the fix as necessary. [I used the arm-soc version with all the conditionals on CONFIG_HAVE_CLK removed.] -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx diff --cc drivers/ata/sata_mv.c index 24712ad,37503b8..0000000 --- a/drivers/ata/sata_mv.c +++ b/drivers/ata/sata_mv.c @@@ -551,10 -551,7 +551,8 @@@ struct mv_host_priv u32 irq_mask_offset; u32 unmask_all_irqs; - #if defined(CONFIG_HAVE_CLK) struct clk *clk; + struct clk **port_clks; - #endif /* * These consistent DMA memory pools give us guaranteed * alignment for hardware-accessed data structures, @@@ -4028,9 -4025,6 +4026,7 @@@ static int mv_platform_probe(struct pla struct resource *res; int n_ports = 0; int rc; - #if defined(CONFIG_HAVE_CLK) + int port; - #endif ata_print_version_once(&pdev->dev, DRV_VERSION); @@@ -4058,13 -4052,6 +4054,11 @@@ if (!host || !hpriv) return -ENOMEM; - #if defined(CONFIG_HAVE_CLK) + hpriv->port_clks = devm_kzalloc(&pdev->dev, + sizeof(struct clk *) * n_ports, + GFP_KERNEL); + if (!hpriv->port_clks) + return -ENOMEM; - #endif host->private_data = hpriv; hpriv->n_ports = n_ports; hpriv->board_idx = chip_soc; @@@ -4074,21 -4061,11 +4068,19 @@@ resource_size(res)); hpriv->base -= SATAHC0_REG_BASE; - #if defined(CONFIG_HAVE_CLK) hpriv->clk = clk_get(&pdev->dev, NULL); if (IS_ERR(hpriv->clk)) - dev_notice(&pdev->dev, "cannot get clkdev\n"); + dev_notice(&pdev->dev, "cannot get optional clkdev\n"); else - clk_enable(hpriv->clk); + clk_prepare_enable(hpriv->clk); + + for (port = 0; port < n_ports; port++) { + char port_number[16]; + sprintf(port_number, "%d", port); + hpriv->port_clks[port] = clk_get(&pdev->dev, port_number); + if (!IS_ERR(hpriv->port_clks[port])) + clk_prepare_enable(hpriv->port_clks[port]); + } - #endif /* * (Re-)program MBUS remapping windows if we are asked to. @@@ -4115,18 -4092,10 +4107,16 @@@ return 0; err: - #if defined(CONFIG_HAVE_CLK) if (!IS_ERR(hpriv->clk)) { - clk_disable(hpriv->clk); + clk_disable_unprepare(hpriv->clk); clk_put(hpriv->clk); } + for (port = 0; port < n_ports; port++) { + if (!IS_ERR(hpriv->port_clks[port])) { + clk_disable_unprepare(hpriv->port_clks[port]); + clk_put(hpriv->port_clks[port]); + } + } - #endif return rc; } @@@ -4142,24 -4111,13 +4132,20 @@@ static int __devexit mv_platform_remove(struct platform_device *pdev) { struct ata_host *host = platform_get_drvdata(pdev); - #if defined(CONFIG_HAVE_CLK) struct mv_host_priv *hpriv = host->private_data; + int port; - #endif ata_host_detach(host); - #if defined(CONFIG_HAVE_CLK) if (!IS_ERR(hpriv->clk)) { - clk_disable(hpriv->clk); + clk_disable_unprepare(hpriv->clk); clk_put(hpriv->clk); } + for (port = 0; port < host->n_ports; port++) { + if (!IS_ERR(hpriv->port_clks[port])) { + clk_disable_unprepare(hpriv->port_clks[port]); + clk_put(hpriv->port_clks[port]); + } + } - #endif return 0; }
