From: Stephen Warren <[email protected]> Tegra's clock driver now provides an implementation of the common reset API (include/linux/reset.h). Use this instead of the old Tegra- specific API; that will soon be removed.

I'm looking for an ack so that I can take the entire series through the Tegra and arm-soc trees. The series will be part of a stable branch that can be merged into other subsystems if needed to avoid/resolve dependencies. --- drivers/input/keyboard/tegra-kbc.c | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) diff --git a/drivers/input/keyboard/tegra-kbc.c b/drivers/input/keyboard/tegra-kbc.c index 8508879f6faf..9757a58bc897 100644 --- a/drivers/input/keyboard/tegra-kbc.c +++ b/drivers/input/keyboard/tegra-kbc.c @@ -31,7 +31,7 @@ #include <linux/clk.h> #include <linux/slab.h> #include <linux/input/matrix_keypad.h> -#include <linux/clk/tegra.h> +#include <linux/reset.h> #include <linux/err.h> #define KBC_MAX_KPENT 8 @@ -116,6 +116,7 @@ struct tegra_kbc { u32 wakeup_key; struct timer_list timer; struct clk *clk; + struct reset_control *rst; const struct tegra_kbc_hw_support *hw_support; int max_keys; int num_rows_and_columns; @@ -373,9 +374,9 @@ static int tegra_kbc_start(struct tegra_kbc *kbc) clk_prepare_enable(kbc->clk); /* Reset the KBC controller to clear all previous status.*/ - tegra_periph_reset_assert(kbc->clk); + reset_control_assert(kbc->rst); udelay(100); - tegra_periph_reset_deassert(kbc->clk); + reset_control_assert(kbc->rst); udelay(100); tegra_kbc_config_pins(kbc); @@ -663,6 +664,12 @@ static int tegra_kbc_probe(struct platform_device *pdev) return PTR_ERR(kbc->clk); } + kbc->rst = devm_reset_control_get(&pdev->dev, "kbc"); + if (IS_ERR(kbc->rst)) { + dev_err(&pdev->dev, "failed to get keyboard reset\n"); + return PTR_ERR(kbc->rst); + } + /* * The time delay between two consecutive reads of the FIFO is * the sum of the repeat time and the time taken for scanning -- 1.8.1.5 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
